Not Found (404)

The resource does not exist for your key. Resources that exist but belong to another partner answer exactly the same — the API never confirms other tenants' data.

Common causes

• An id from a different environment (sandbox ids never exist in production).
• A webhook endpoint that was deleted (deletion is immediate and ids are not reused).
• church_id that your key never imported.

What to do: list the parent collection (GET /v1/churches, GET /v1/webhook_endpoints) and use ids from the response.
