The creator gets it as onboarding feedback in the app, by push, and in Discord. Nothing else changes. While a proof from the creator waits for review, the message is not sent and the request returns `409` with `code: proofs_waiting`. Approve or reject the proof instead; a rejection carries its own message to the creator. ## OpenAPI ````yaml /api-reference/openapi.json post /onboarding/{creatorId}/messages openapi: 3.0.4 info: title: Launchpoint Public API version: 1.0.0 description: >- **Private preview.** The Launchpoint Public API is in private preview and available only to trusted partners we work with directly. Access is not self-serve. Email hi@launchpointhq.com to ask about access. REST API for Launchpoint brands and agencies. Use an API key in the `x-api-key` header to authenticate. ## Requirements - Public API access must be enabled for the company. During private preview, access is limited to trusted partners. - Create and manage API keys in Dashboard → Settings → Developer. ## Creator privacy - Responses never include creator email addresses. Creator phone numbers are null when no number is stored or the workspace does not have access to creator contact details. ## Rate limits - Default: **100 requests per minute** per API key. - Approved partner accounts: **400 requests per minute**. - Every response includes `X-RateLimit-Limit`, `X-RateLimit-Remaining`, and `X-RateLimit-Reset`. Requests over the limit return `429`. ## Errors - Errors use `{ "error": "" }` with the matching HTTP status. Some endpoints also include a `code`. ## Timestamps - Timestamps are Unix timestamps in milliseconds unless a field says otherwise. ## Pagination - Most list endpoints accept `page` and `limit` and return `{ data, page, total }`. Some also return `totalPages`. - `scope=company` is the default. A parent agency key can pass `scope=agency` on supported routes to include its own data and linked brands. servers: - url: https://dashboard.launchpointhq.com/api/v1 description: Live API server security: - apiKeyAuth: [] tags: - name: Deals description: Public creator opportunities across Launchpoint - name: Programs description: Programs and campaign management - name: Posts description: Posts and social content - name: Analytics description: KPIs and performance metrics - name: Payouts description: Payouts, balances, and pending creator funds - name: Contracts description: Contracts and creator agreements - name: Creators description: Creator profiles and metrics - name: Applications description: Creator applications to Canvas programs - name: Messages description: Read and send creator messages - name: Onboarding description: 'Creator onboarding: status, messages, and proof review' - name: Media review description: >- Review the media creators send before they post: queue, status, approve, and reject paths: /onboarding/{creatorId}/messages: post: tags: - Onboarding summary: Send an onboarding message description: >- Send the creator a message about their onboarding, for example to ask them to link Instagram and send a proof.
