Transitions a draft subscription to active so it becomes effective for the customer. Idempotent: activating an already-active subscription returns the current state. See the Creating a Subscription examples for the full creation flow.

Authorizations

Authorization · string · header · required

API key authentication. Pass your API key as a Bearer token.

Headers

Alguna-Version · enum<string> · required

Available options: 2026-04-01

Idempotency-Key · string

A unique string that makes a retried write safe. If you send the same request with the same key within 24 hours, the API returns the stored response and does not run the request again. A 5xx or 429 response is not stored, so a retry with that key runs the request again.

Maximum string length: 255

Example:

"ik_a1b2c3d4e5f6"
