Must be called by the contract’s matched
worker — any other caller is rejected. Only valid while status is matched; if the Delivery Deadline has already passed, the contract auto-cancels (cancelled-absent) before this call could meaningfully succeed, and it’s rejected instead.Path Parameters
string
required
The contract ID.
Request Body
string
required
Reference (hash/URI) to the Worker’s output, encrypted the same way as Supplementary Materials.
Response
Returns the updated contract — see Get Contract for the full response shape.status becomes under-review, delivery is set. The Review Deadline set at Create Contract is unchanged — it isn’t extended or recalculated from the delivery time.
For a TokenSwap ticket (application: "tokenswap"), criteriaMet is also filled in immediately by this call — see Settlement. There’s nothing subjective left for the Client to review, so Approve Delivery resolves using this already-computed result rather than defaulting to met.
