idempotency-key-conflict

HTTP status: 422 Unprocessable Entity Type URI: https://docs.evinor.ai/problems/idempotency-key-conflict

You reused an Idempotency-Key that was already used for a different request. A key is bound to the first request's method, path, and body; sending a different request under the same key is a conflict.

Common causes​

  • Reusing one idempotency key across unrelated operations.
  • Retrying with the same key but a changed request body.

How to resolve​

Use a fresh, unique idempotency key for each distinct operation. Only reuse a key when you are retrying the exact same request (same method, path, and body). See Idempotency.
