confirm_transaction_step

Confirm transaction step

Apply a prepared transaction step after the buyer said yes to you in this conversation, through the same service the website uses. It records the buyer's word only: it signs, pays, contacts, and sends nothing and changes no contingency or deadline. Refused if the task, repair request, or package changed since preparation or the prepared action expired. Reuse confirmationIdempotencyKey only for an exact retry.

Effect
Buyer decision
Required scopes
transaction:confirm
Workflow stages

Data classes

Operation cost
3 weighted units; additional domain limits may apply.
Configurations

Sensitive write. Records a consequential buyer decision against an exact prepared action. Meta makes the final classification during review.

Buyer approval and signing controls apply in addition to the scopes above. Read error and retry guidance before implementing recovery.
