How to connect GrowSurf MCP with Codex

Plan a web integration for a referral or affiliate program. Returns Markdown steps for installing the Universal Code, identifying participants, tracking referrals or sales, and verifying webhooks. Does not inspect or change a program. Use `growsurf_client_snippets` for browser JavaScript examples, `growsurf_api_library_snippets` for backend code, or `growsurf_mobile_sdk_guide` for native or React Native apps.

Generate Markdown prompts and acceptance checks for evaluating an agent's program-creation workflow: starter content, rewards, configuration, and frontend installation. Does not create a program or run the checks. Use `growsurf_program_design_advisor` to choose a program design, or `growsurf_integration_guide` to plan its web integration.

Generate program designs, benchmarks, typical rewards, and metric definitions, including participant-to-referral and lead-to-referral ratios. Read-only. Returns a short draft, complete `benchmarkFacts`, a proposed `configurationPlan`, and unresolved `decisions`. Incentive amounts and qualifying actions remain unresolved unless supplied by the customer. `detail: summary` returns a configuration draft and reward structure; `detail: full` adds detailed benchmark tables. Hosted figures describe GrowSurf's high-performing programs; without a bundle, guidance is documentation-based. `programType: AFFILIATE` selects affiliate advice. `industry: other` covers local services, pets, hospitality, and agencies. All inputs are optional.

Diagnose referral tracking and program problems. Accepts a symptom or description without requiring a program or participant ID. Covers referrals not credited, participant emails not sending, rewards not issued, participants not added, Universal Code not detected, integrations or CRMs not syncing, Zapier errors, fraud flags, and analytics discrepancies. Returns ordered diagnostic checks, likely causes, fixes, and documentation links. It does not read program or participant records. Unknown `symptom` keys return the available symptoms. A `description` matches only when it contains a symptom label or alias verbatim; otherwise the symptom list is returned.

Get Markdown implementation guidance for native iOS/Android SDK 0.10.1 or React Native SDK 0.2.0, including attribution, `shareUrl` sharing, `trackShare`, and the native GrowSurf Window. Choose `platform` and `participantState` to tailor the guide; `includeInstallSnippets` controls installation examples. Does not install an SDK or create a participant token. Use `growsurf_client_snippets` for browser JavaScript or `growsurf_api_library_snippets` for backend token-creation code.

Generate Markdown code examples for the official backend REST API libraries in TypeScript, Python, PHP, Ruby, and Java. Select `language` and `workflow`; both default to `all`. Covers setup, program lookup, participant creation, referral credit, sales, and mobile participant tokens. Returns code without executing API calls. Use `growsurf_client_snippets` for browser JavaScript or `growsurf_mobile_sdk_guide` for native or React Native app setup.

Fetch your GrowSurf campaign (program) details via REST. Embedded reward settings do not establish that an individual reward was earned, approved, or delivered. Earned reward records belong to the individual participant. Targets `campaignId` if supplied, otherwise `GROWSURF_CAMPAIGN_ID`.

List the GrowSurf programs available to the bound team, including their IDs for program selection. Deleted programs are not returned. Does not require `GROWSURF_CAMPAIGN_ID`.

Create a new GrowSurf program (campaign) with type-appropriate starter content and optional inline rewards. Starter content includes Design, Emails, Options, Installation, and GrowSurf Window defaults. Only `type` is required. The program starts in `DRAFT` status and is owned by the credential's bound team. `currencyISO` defaults to `USD` and is immutable after creation. `goal` sets the sharing settings at creation and cannot be set later. Incentives require the customer's chosen amount or commission rate. Without `rewards`, GrowSurf's starter rewards are switched off and award nothing. Editor-tab configuration is not accepted here. Does not require `GROWSURF_CAMPAIGN_ID`. The response includes the new program `id`.

Update your GrowSurf program's (campaign's) identity and lifecycle: name, companyName, companyLogoImageUrl, and status (set IN_PROGRESS to publish/resume the program, COMPLETE to end it). Only the fields you send are changed. `type`, `urlId`, and `currencyISO` are immutable (currency is chosen once at program creation), so this tool does not accept them. Editor-tab config (design, emails, options, installation) is edited with the dedicated config sub-resource tools, not here. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Clone your GrowSurf program (campaign) into a new DRAFT program. Integrations and credentials are not copied; active rewards are cloned. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

List your GrowSurf program's configured Campaign Rewards, including switched-off rewards and rewards whose group is not selected. Deleted rewards are excluded. A reward can be earned only when it also appears in the campaign response's embedded `rewards` array. These settings do not establish that a participant earned or received a reward; earned reward records belong to the individual participant. Targets `campaignId` if supplied, otherwise `GROWSURF_CAMPAIGN_ID`.

Create a new campaign reward (reward config) on your GrowSurf program. `type` must be compatible with the program type (affiliate programs support only AFFILIATE rewards; referral programs support the other types). Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Update an existing campaign reward (reward config) on your GrowSurf program. `campaignRewardId` is the reward key (e.g. crew_...). The reward `type` is immutable. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Delete a campaign reward (reward config) from your GrowSurf program. The reward is deactivated, removed from the program's reward set, and any connected upfront-discount coupons are cleaned up. `campaignRewardId` is the reward key. Returns { id, success }. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

List the participant resources configured for your GrowSurf program, including drafts. Results stay in display order. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Prepare a local file for a `FILE` Program Resource. Accepts a safe file name, matching supported MIME type, and padded base64 bytes, up to 10 MB. GrowSurf requests a one-time ticket and uploads only to the secure HTTPS destination selected by GrowSurf. Returns the original `uploadTicket` and `uploadResult` required for file resource creation or replacement. Altered upload results are not valid. The tool does not accept upload URLs or credentials and never retries an ambiguous upload. Requires `GROWSURF_UPLOAD_ALLOWED_ORIGINS` on the server; without it, only `LINK` and `TEXT` resources are available. Targets `campaignId` if supplied, otherwise `GROWSURF_CAMPAIGN_ID`.

Create a `FILE`, `LINK`, or `TEXT` resource for participants. `LINK` requires an HTTPS `url`. `TEXT` requires plain `text`. A `FILE` up to 10 MB requires a one-time `uploadTicket` and the unmodified `uploadResult` from GrowSurf's secure upload flow. New resources default to draft unless `isPublished` is set. API reference: https://docs.growsurf.com/developer-tools/rest-api/api-reference. Targets `campaignId` if supplied, otherwise `GROWSURF_CAMPAIGN_ID`.

Update at least one participant resource field, or move it to a zero-based `position`. Only supplied fields change. A replacement `FILE` requires a one-time `uploadTicket` and the unmodified `uploadResult` from GrowSurf's secure upload flow. API reference: https://docs.growsurf.com/developer-tools/rest-api/api-reference. Targets `campaignId` if supplied, otherwise `GROWSURF_CAMPAIGN_ID`.

Delete a participant resource from your GrowSurf program. This does not remove its reusable Media Center asset. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Fetch the configured design fields for your GrowSurf program, including GrowSurf Window content, colors, sharing sections, participant avatars under `participantAvatarStyle`, referred-visitor content such as the Claim Offer Popup, the website widget under `widget`, the participant Traffic report under `trafficInsights` (it starts on for new affiliate programs and hidden for referral programs, and every setting is returned with its default copy), participant sign-in copy under `login`, payout-destination confirmation page copy under `payoutDestinationConfirmation`, country-name overrides under `countryLabels`, and the participant Settings panel under `participantSettings` (its `languageSectionTitle` and `languageSectionInstructionsText` label the language picker shown when the program has more than one language). `participantAvatarStyle` is `CHARACTERS`, `INITIALS`, `ANIMALS`, or `GRADIENT`; missing or unknown values mean `INITIALS`. The confirmation section is omitted when no confirmation fields are stored. Stored `null` fields are returned as `null`; omitted and `null` fields use localized defaults. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Update the design configuration for your GrowSurf program, including participant avatars under `participantAvatarStyle`, referred-visitor content such as the Claim Offer Popup and the side content of its GrowSurf page (`referredExperience.offerPageDescription` HTML, up to 5 `offerPageSteps` of `{ text, iconKey }`, and up to 3 `offerPageLinks` of `{ text, url }` where an empty `url` links to the Share URL), the website widget under `widget` (button or card, placement, timing, and visible pages), the participant Traffic report under `trafficInsights`, participant sign-in copy under `login`, payout-destination confirmation page copy under `payoutDestinationConfirmation`, and the participant Settings panel under `participantSettings`, such as the language picker's `languageSectionTitle` and `languageSectionInstructionsText` (up to 500 characters each). `trafficInsights.isPublicDisplayed` controls visibility; its labels cannot be blank. `participantAvatarStyle` accepts `CHARACTERS`, `INITIALS`, `ANIMALS`, or `GRADIENT`. Only supplied `fields` change; omitted fields retain their existing content and arrays replace wholesale. Targets `campaignId` if supplied, otherwise `GROWSURF_CAMPAIGN_ID`.

Fetch the Emails tab configuration for your GrowSurf program, including participant and admin email templates, settings, and read-only fields. `settings.sender.fromEmail` is read-only and can be changed in the dashboard after domain verification. Sender fields can be `null` before configuration. When updating, omit unchanged sender fields; `fromName` and `replyToEmail` cannot be cleared with `null`. Targets `campaignId` if supplied, otherwise `GROWSURF_CAMPAIGN_ID`.

Update writable Emails tab fields for your GrowSurf program under `fields`, in their existing nested shape. `settings.sender.fromEmail` is read-only; sender address changes require domain verification in the dashboard. `settings.sender.fromName` and `settings.sender.replyToEmail` accept non-empty strings, not `null`. Omit either field to keep its current value, including an unset value returned by a read. The `invite` and transactional email `isEnabled` toggles are read-only. Email bodies require their template links and footer tokens. When `settings.design.layoutMode` is `INLINE`, each body must include `{{emailFooter}}`; `{{emailHeader}}` is optional. `layoutMode` is read-only. Omitted fields retain their existing content; arrays replace wholesale. Targets `campaignId` if supplied, otherwise `GROWSURF_CAMPAIGN_ID`.

Fetch the Options tab configuration for your GrowSurf program (referral triggers, anti-fraud lists and toggles, affiliate enrollment and application review, notifications, the program's languages under `languages`, and other behavior options). Returns the full object with every field and its current value, the same shape you send back on update. `autoFulfillRewards: false` permits manual fulfillment and does not prove that any reward went undelivered. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Update the Options tab configuration for your GrowSurf program under `fields`, in its existing nested shape. Only supplied fields change; omitted fields retain their existing values and arrays replace wholesale. `languages.additionalLanguages` takes the full list of extra languages; send `[]` to turn them off. The base language is dropped from that list and duplicates collapse. `languages.showFlags` shows or hides the flag next to each language name. Turning languages on, and any change while they are on (including turning them off or changing `showFlags`), requires the Business plan or higher and returns a `403` otherwise. Translations are managed in the GrowSurf dashboard, not through this tool. Targets `campaignId` if supplied, otherwise `GROWSURF_CAMPAIGN_ID`.

Fetch the Installation tab configuration for your GrowSurf program (embed/installation and tracking setup). Returns the full object with every field and its current value — the same shape you send back on update. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Update the Installation tab configuration for your GrowSurf program under `fields`. Only supplied fields change; omitted fields retain their existing values and arrays replace wholesale. `allowedUrls` includes permitted browser origins such as `http://localhost:3000`. An origin missing from both `shareUrl` and `allowedUrls` can return `403`. Referral links already shared point at the current `shareUrl`. Replacing an existing Share URL requires the customer's explicit approval and `replaceExistingShareUrl: true`; otherwise the patch is refused. Targets `campaignId` if supplied, otherwise `GROWSURF_CAMPAIGN_ID`.

Capture temporary GrowSurf preview screenshots after a draft program is saved. Returns short-lived URLs for the controlled referrer Window and referred-friend experience, with an `expiresAt` timestamp in UTC. The screenshots reflect the saved program at capture time and do not verify installation on the customer's site. A failed inline image alone does not establish that the URL expired. This tool does not accept arbitrary URLs, HTML, JavaScript, or external screenshot targets. Targets `campaignId` if supplied, otherwise `GROWSURF_CAMPAIGN_ID`.

Create a brand-new GrowSurf account and return an API key. Requires the authorized owner's explicit approval of account creation and acceptance of GrowSurf's Terms of Service (https://growsurf.com/terms) and Privacy Policy (https://growsurf.com/privacy). This is the only tool that does not require `GROWSURF_API_KEY`. The account starts a 14-day Business trial without a credit card. The new key is returned once in `apiKey`, cannot be recovered through this API, and requires durable secret storage. The hosted OAuth connector is an alternative that retains credentials with the connection. The key stays locked until the owner verifies their email; program and resource endpoints return `403` with `EMAIL_NOT_VERIFIED_ERROR` before verification. Verification unlocks the same key. The welcome email includes verification and set-password links. Unverified accounts are deleted after 7 days. The owner's first dashboard sign-in replaces the API key; the old key then returns `403` with `NOT_AUTHORIZED_ERROR`. Participant emails also require team verification. Personal and disposable email addresses are not accepted.

Fetch the team bound to the API key or OAuth connection. `verificationStatus` is `VERIFIED` once GrowSurf has verified the team, which is required before a program can email participants. Personal profiles and internal identifiers are not returned. Requires `GROWSURF_API_KEY`; does not require `GROWSURF_CAMPAIGN_ID`.

Update the display name of the team bound to the API key or OAuth connection. Personal profiles, billing, and team ownership are not editable here. Requires `GROWSURF_API_KEY`; does not require `GROWSURF_CAMPAIGN_ID`.

Ask GrowSurf to verify the team bound to the API key or OAuth connection. Verification is required before a program can email participants. Calling this again while a request is pending does not create a duplicate. Returns the team with its updated `verificationStatus`. Requires `GROWSURF_API_KEY`; does not require `GROWSURF_CAMPAIGN_ID`.

Resend the email-verification message to the bound team's owner. The response never reveals the owner's email address. A `200` with `status: SENT` is returned only when an email was sent. Returns `400` if the email is already verified and `429` if one was sent too recently. Requires `GROWSURF_API_KEY`; does not require `GROWSURF_CAMPAIGN_ID`.

Fetch analytics for your GrowSurf program: participants, referrals, impressions, per-channel shares, and affiliate revenue, commission, and payout metrics when applicable. Pass `interval` (`day`, `week`, or `month`) for a per-period `series`. Pass comma-separated `include` values for `previousPeriod`, `statusCounts`, `rates`, `email`, or `engagement`. `engagement` groups unique active, sharing, repeat, and retained participants by when portal views and share actions occurred. Its `coverageStartAt`, `state`, and `reason` distinguish measured zeroes from partial or unavailable history. Scope the timeframe with `days` (default 365, max 1825) or an explicit `startDate`/`endDate` window. Explicit dates must both be positive Unix timestamps in milliseconds, with `endDate` >= `startDate` and a maximum span of 1825 days. `timezone` and `platform` apply to engagement only. Targets `campaignId` if passed, otherwise `GROWSURF_CAMPAIGN_ID`.

Fetch strict activation for eligible participants in one enrollment cohort. Referral programs group by `enrolledAsAdvocateAt`; affiliate programs group by `approvedAsAffiliateAt`. The ordered stages are `ELIGIBLE`, `PORTAL_VIEWED`, `SHARE_ACTION`, `UNIQUE_REFERRAL_VISIT`, `LEAD`, and `CREDITED_REFERRAL`. Each participant gets the selected 7- or 30-day observation window. Omit both cohort bounds for the latest fully matured cohort. Read `coverageStartAt`, `state`, and `reason` before interpreting a null or zero; unavailable history does not mean an action never happened. Targets `campaignId` if passed, otherwise `GROWSURF_CAMPAIGN_ID`.

List the integrations available to your GrowSurf program, including Stripe, PayPal, Wise, Mailchimp, Slack, Zapier, and Webhooks. Each entry includes `connected` (credentials stored), `enabled` (working), `autoDisabled` (delivery stopped after repeated failures until the user reconnects), and `connectUrl` (dashboard connection link). Integrations that do not apply to the program type are omitted, such as Wise on a referral program. Read-only. Account connection takes place in the GrowSurf dashboard and is not available through the API. Targets `campaignId` if supplied, otherwise `GROWSURF_CAMPAIGN_ID`.

List your GrowSurf program's webhooks (secrets are never returned). Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Add a webhook to your GrowSurf program. `payloadUrl` is required. `events` is the list of events this webhook is subscribed to (omit to subscribe it to no events). `secret` is write-only — GrowSurf uses it to sign deliveries (the GrowSurf-Signature HMAC header) and never returns it. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Update a webhook on your GrowSurf program by id (`webhookId` is `primary` for the program's primary webhook). Only the fields you send are changed. `secret` is write-only and never returned. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Remove a webhook from your GrowSurf program by id. Returns { id, success }. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Send a live test event to a webhook on your GrowSurf program using its stored URL and secret. Optionally pass `event` to choose which event type to simulate; when omitted, the webhook's first enabled event is used (returns 400 if the webhook has no enabled events). Returns the mock payload and the receiving endpoint's response. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

List participants in your GrowSurf program, newest page first. `limit` is 1-100 (default 10). Pass response `nextId` into the next call to continue paging. Pass `metadata` to return only participants whose stored metadata matches every given key and value exactly, for example `{ "customerId": "12345" }` to look someone up by your own customer ID; filtered results are ordered by participant ID. Results include participant IDs. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Fetch a single participant by GrowSurf participant ID or email address. `referralStatus` describes credit to their referrer; `referralCount` counts referrals this participant generated, so zero is consistent with `CREDIT_AWARDED`. In `rewards`, `approved` records approval; `status`, `isFulfilled`, and `fulfilledAt` record fulfillment marking, not confirmation of delivery. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Add or fetch a participant by email. Existing participants are returned unchanged. This is trusted direct enrollment and bypasses the public application review flow for affiliates. For affiliate programs, set `isAffiliate` to `true` to enroll a new participant as approved or `false` to create a non-affiliate. If you omit it, a valid `referredBy` creates a referred non-affiliate; without a valid referrer, the new participant is enrolled as approved. A valid `referredBy` can be combined with `isAffiliate: true`. Targets `campaignId` if you pass it, otherwise `GROWSURF_CAMPAIGN_ID`.

Update a participant by GrowSurf participant ID or email. Only the fields you send are changed; read-only fields such as counters, `isAffiliate`, `origin`, and fraud state are rejected with a `400`. In affiliate programs, `affiliateStatus` accepts `APPROVED`, `SUSPENDED`, or `BANNED`; `APPROVED` enrolls the participant, while `SUSPENDED` and `BANNED` require an existing affiliate. Affiliate enrollment cannot be removed through REST. `notes` is freeform internal notes (never shown to participants). Targets `campaignId` if you pass it, otherwise `GROWSURF_CAMPAIGN_ID`.

Bulk delete participants from your GrowSurf program in one request. DESTRUCTIVE: deletion is permanent and cannot be undone. Successful rows lose participant access immediately; related record cleanup completes automatically, subject to required financial record retention. Each entry in `participants` is a GrowSurf participant ID or an email address (mixed lists are allowed), up to 200 entries per request — chunk larger lists across multiple calls. Returns a `summary` (total, deletedCount, notFoundCount, duplicateCount, errorCount) plus per-row `results` in request order, each with `status` DELETED, NOT_FOUND, DUPLICATE (resolves to the same participant as an earlier entry), or ERROR — both `200` and `202` responses can include NOT_FOUND or ERROR rows, and the summary reports these outcomes. A `202` response includes `analyticsErasure` when analytics erasure is pending. `DELETED` means participant access was removed; reports can retain the participant until cleanup completes. Do not repeat successful rows to finish cleanup. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Send an email to a participant (by GrowSurf participant ID or email). Provide EITHER `emailType` to trigger one of the program's configured email templates, OR `subject` + `body` for a free-form email (optionally `preheader`). For programs with `settings.design.layoutMode` set to `INLINE`, `body` must include `{{emailFooter}}`; `{{emailHeader}}` is optional. Free-form emails are sent with the same compliance handling (company name, postal address, and an unsubscribe link are added automatically, and unsubscribed participants are suppressed). Sending requires the team to be verified by GrowSurf and a verified custom email domain on the program (set up in *Program Editor > 3. Emails > Email Settings*). Returns 400 until one is verified. The email is accepted for delivery. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Fetch analytics for one participant by GrowSurf participant ID or email. The base response includes all-time engagement, rank, share, and applicable affiliate revenue, commission, and payout metrics. Add `activation` to `include` for the program-specific eligibility anchor and covered first milestones, including `firstPortalViewedAt` and `firstShareChannel`. A null milestone with a partial or unavailable `state` is unknown, not proof that the action never happened. Request both `activation` and `series` for covered `portalViews` and `shareActions` buckets. Filter optional series and email data with `days` (up to 1825) or both `startDate` and `endDate` as positive Unix timestamps in milliseconds. `endDate` must be at or after `startDate`, and the range can span at most 1825 days. These date parameters do not filter the base response or activation milestones. Targets `campaignId` if passed, otherwise `GROWSURF_CAMPAIGN_ID`.

List a participant's activity logs (by GrowSurf participant ID or email), most recent first, offset/limit paginated. `limit` is 1-100 (default 20); `offset` skips logs. The response `offset` is the cursor for the next page (null when there are no more). Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Trigger referral credit for a referred participant (use when your trigger is Sign up + Qualifying Action). Optionally pass delayInDays (1-90) to hold the credit for N days before awarding it (e.g. to cover a refund window). Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Cancel a pending delayed referral trigger for a participant before the delay elapses (e.g. on refund/cancellation). Returns { success, message }. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Get a participant's payout-destination status (by GrowSurf participant ID or email) across every payout provider enabled for the program (PayPal and/or Wise). For each provider it reports the current `status`, the confirmed payout email, the legal recipient type, and — when a delivery bounced or a recipient was invalidated — the repair reason. `activeProvider` is the provider that currently gets paid, or null until the participant confirms one. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Ask a participant to confirm their payout destination for a provider (by GrowSurf participant ID or email). Sends them a one-time confirmation link for the chosen `provider`; only the participant can open the link and confirm — this just triggers the message, and the provider must be enabled for the program. Returns { status, provider, providerDisplayName, expiresAt }. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Record a sale/transaction for an affiliate program. Use webhooks to know when commissions are added. Requires at least one transaction identifier (externalId, transactionId, orderId, paymentId, invoiceId, paymentIntentId, or chargeId) so repeated calls are de-duplicated instead of double-paying the referrer; reuse the same one when refunding. Targets `campaignId` if you pass it, otherwise GROWSURF_CAMPAIGN_ID.

Record a refund, partial refund, or chargeback for a previously recorded affiliate transaction in GrowSurf and reverse or adjust the referrer's commission. This records the amendment without sending a refund through the payment provider. Requires the same transaction identifier as the original sale. Omitted `amountRefunded` means a full refund. Already-paid commissions are not clawed back and are recorded for tax only. Targets `campaignId` if supplied, otherwise `GROWSURF_CAMPAIGN_ID`.

Create or fetch a participant, then create a participant-scoped mobile SDK token via GrowSurf REST. Participant creation is trusted direct enrollment and bypasses the public application review flow for affiliates. Targets `campaignId` if you pass it, otherwise `GROWSURF_CAMPAIGN_ID`.

Compute a SHA-256 HMAC using the caller-supplied `participantAuthSecret`. Server environment secrets are never used. Use a test secret during implementation; keep production signing in your backend. `affiliateJoin` requires permission for this signed-in user to join the affiliate program directly.

Validate/normalize a GrowSurf webhook payload and generate a best-effort idempotency key for dedupe.

Generate Markdown browser JavaScript and CSS examples for referral tracking, embeddable elements, and the GrowSurf Window, with placement guidance. Does not install code or change a program. Use `growsurf_embeddable_element_snippet` for one HTML element, `growsurf_grsf_config_snippet` for `window.grsfConfig`, or `growsurf_api_library_snippets` for backend REST code.

Generate one embeddable element's HTML as Markdown. Choose `element`; optionally include participant authentication attributes. Does not install the element or change a program. Use `growsurf_client_snippets` for a broader browser integration or `growsurf_grsf_config_snippet` for page-level participant auto authentication.

Generate the HTML code for GrowSurf Participant Auto Authentication using `window.grsfConfig`. The generated code belongs in `<head>`, before the GrowSurf Universal Code.

Return a dashboard link to an integration's connect panel in the GrowSurf Program Editor (Options > Integrations). Connecting Stripe, PayPal, Wise, or another account requires the user to complete the dashboard flow; the API cannot connect an account on their behalf. `integration` accepts supported keys, including camelCase keys such as `constantContact` and `helpScout`. The result reports whether the integration is `connected`, `enabled`, or `autoDisabled`. If the program check cannot run, `programVerified` is `false` and the result still includes a production dashboard link. Tango Card, Tremendous, and Bask Health apply only to referral programs. Wise applies only to affiliate programs. Targets `campaignId` if supplied, otherwise `GROWSURF_CAMPAIGN_ID`.
