Headers

x-idempotency-key
string<uuid>
required

Unique key (UUID) to ensure request idempotency on POST, PUT and PATCH requests.

A key is scoped to your client, the HTTP method and the path, and is remembered for 24 hours after a successful (below 400) response. Repeating the same request (same JSON body, whatever the key order or whitespace) with the same key within that window returns the original response with X-Idempotent-Replayed: true instead of executing the request again. Using the same key on the same endpoint with a different body returns 422 with problem type idempotency-key-reused; the request is not executed. Error responses (4xx and 5xx) are not remembered, so a request refused for a fixable reason can be corrected and retried under the same key. Request bodies that are not JSON (for example file uploads) are not compared.

Body

signatures
string[]

List of signatures over the intent

Cryptographic signature over the intent, base64-encoded. For an ES256 signer this is the ASN.1 DER ECDSA signature over the SHA-256 of the canonical intent. For a WEBAUTHN signer this is the base64 of the WebAuthn assertion JSON (id, rawId, type, and response.authenticatorData / clientDataJSON / signature). See the WebAuthn & Passkey Signing guide.
