JSON 
{
  "data": {
    "subscription_id": 123,
    "subscription_event_ids": [
      901
    ],
    "todo": null,
    "state": {
      "status": "available",

    }
  }
}

Behavior and constraints

State changes reject future timestamps (422) and dates preceding newer relevant state changes (409). Omit event_date to use now. Free subscriptions have no billing and return 409. Restore final subscriptions before changing billing. The billing type cannot be changed. Each accepted billing action records history; retries with the same key replay it.

Errors

401 means the token is missing, expired, revoked, or not a customer API token. 403 means a required permission or administrator access is missing. 404 means the record or child record is unavailable in this organization. 422 identifies invalid or unsupported input; inspect the errors object when present. 409 indicates a conflicting state or concurrent change; inspect the message and refresh the record before deciding how to proceed. Reusing an idempotency key with a different method, path, or body also returns 409. 429 means a rate limit was reached. See error handling and rate limits.
