Create an Authorization

authorizations have six states, two of which are expected: SUCCEEDED and FAILED. If an authorization has succeeded, it must be captured before the date in expires_at passes. If the date in expires_at passes, the funds get released.

Learn how to prevent duplicate authorizations by passing an idempotency ID in the payload.

warning

Authorizations on debit cards place a hold on funds in the cardholder's bank account and can lead to lower than expected balances or issues involing insufficient funds.

attention

If the transfer field of an authorization is null, it has not been captured yet.
