> Adds a membership plan category. Omit `sortOrder` and it goes to the end of the list, which is what you want unless you are rebuilding the whole ordering. Supports the `Idempotency-Key` header.




## OpenAPI

````yaml /openapi-platform.json post /v1/platform/plan-categories
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

    | `400` | Invalid request parameters |

    | `401` | Missing or invalid API key |

    | `404` | Resource not found (or doesn't belong to your organization) |
