List the existing types first - most organizations already have one for each sport their clubs offer, and this endpoint will happily create a near-duplicate. `slug` is optional and derived from the name when omitted, suffixed if that is taken; an explicit slug that clashes is a 409. Supports the `Idempotency-Key` header. ## OpenAPI ````yaml /openapi-platform.json post /v1/platform/instructor-types 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. ## 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 | contact: name: 1club API Support email: support@1club.ai servers: - url: https://api.1club.ai description: Production API security: - customerApiAuth: [] tags: [] paths: /v1/platform/instructor-types: post: tags: - Instructors summary: Create an instructor type description: > Adds a kind of coach.
