The adjustment lasts for the current allowance period; the next one starts from the allowance again. Supports the `Idempotency-Key` header. ## OpenAPI ````yaml /openapi-platform.json post /v1/platform/memberships/{id}/session-adjustments openapi: 3.0.0 info: title: 1club Platform API version: 1.0.0 description: >- The 1club Platform API lets you programmatically access and manage your organization's data. ## Official API Contract This documentation is the official source of truth for the 1club Platform API. If an integration relies on undocumented endpoints, fields, response shapes, or internal behavior outside this spec, we can't guarantee backward compatibility. Build against what's documented here to stay stable as the platform evolves. ## Authentication All requests require a customer API key passed as a Bearer token: ``` Authorization: Bearer 1club_sk_live_... ``` Generate API keys from the admin portal under **Settings > API Tokens**. The key is tied to your organization - all responses are scoped to your org's data. Agents and MCP connectors can instead send an OAuth access token (the `platformOAuth` scheme), requesting only the scopes the task needs. ## Rate Limiting - **100 requests per minute** per API key - When exceeded, the API returns `429 Too Many Requests` with a `Retry-After` header - Rate limit headers are included in every response: - `X-RateLimit-Limit` - max requests per window - `X-RateLimit-Remaining` - requests remaining - `X-RateLimit-Reset` - seconds until the window resets ## Errors | Status | Meaning | |--------|---------| | `400` | Invalid request parameters | | `401` | Missing or invalid API key | | `404` | Resource not found (or doesn't belong to your organization) | | `429` | Rate limit exceeded | | `500` | Internal server error | ## Versioning and deprecation The API is versioned in the path (`/v1`). Changes within a version are additive: new endpoints, new optional parameters and new response fields can appear at any time, so clients should ignore fields they do not recognise. A breaking change ships as a new version. An operation due to be removed is first marked `deprecated: true` in this spec and announced in the changelog at https://docs.1club.ai/changelog, with advance notice before it is withdrawn. contact: name: 1club API Support email: support@1club.ai servers: - url: https://api.1club.ai description: Production API security: - customerApiAuth: [] - platformOAuth: [] tags: [] paths: /v1/platform/memberships/{id}/session-adjustments: post: tags: - Memberships summary: Adjust a membership's sessions description: > Gives a pass sessions or takes some back, with a reason, recorded on the membership as staff adjustments in 1club are.
