`contractorOps.payments.select`

Choose a contractor's default from their saved payment methods by paymentMethodId, with the paymentProfileRevision from contractorOps.payments.list as expectedRevision (null when none). Finance or an administrator can select one; no bank details pass through this call. The new default must be confirmed before a payout can be sent, approvals need review, saved funding previews expire and existing schedules are invalidated. The contractor and administrators are notified.

Fields

contractorIdstring (ID)Required
The ID of a contractor, from contractors.list.
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.
