`payment.select`

Choose your default from your own saved payment methods by paymentMethodId, using paymentProfileRevision as expectedRevision (null when none). Finance must confirm the new default before sending a payout; earlier payout approvals and schedules need review. You and your employer's administrators are notified.

Fields

paymentMethodIdstring (ID)Required
The ID of the related record.
expectedRevisioninteger or nullRequired
The record's current revision, from the last time you read it. If someone changed the record since, the request is refused with a conflict so you can reload and check before trying again.
idempotencyKeystringRequired
Any unique text you generate once per intended change, so a retried request only happens once. Send it as the Idempotency-Key header instead if you prefer; if you send both they must match.
