Must be called by the contract’s client — any other caller is rejected. Only valid while status is under-review and before the Review Deadline. Not calling this — or Dispute Delivery — and just letting the Review Deadline pass has the same effect; this only exists to skip the wait.

No payment is attached to this call — approving doesn’t post or move any bond, only Dispute Delivery does. Approving sets every entry in criteriaMet to met, the same outcome an unchallenged delivery reaches automatically once the Review Deadline passes — see Acceptance Criteria.

Path Parameters

string

required

The contract ID.

Response

Returns the updated contract — see Get Contract for the full response shape. status becomes resolved, criteriaMet is filled with met for every criterion. Settlement follows from there the same way it would once the Review Deadline passes unchallenged.
