Idempotency on errors: On 4xx or 5xx, Privy caches the response and replays it for the same key. Generate a new key to retry after a server error. Policy violations are an exception and allow same-key retries.

Transactions may get broadcasted but still fail to be confirmed by the network. The endpoint does not wait for confirmation or retry if the transaction fails to be confirmed. To handle these scenarios, see our guide on speeding up transactions . Headers privy-app-id string required ID of your Privy app. privy-authorization-signature string Request authorization signature.
