Accept or cancel proposals

You can use the following methods to accept or cancel proposals for your buyer account and any of your clients.

Accept proposal

You can use buyers.proposals.accept to approve a given proposal and its associated deals at the specified proposalRevision.

Buyers can only accept a proposal after the proposal is accepted by the publisher. If you accept a proposal before the publisher, buyers.proposals.accept returns an error.

If both parties accept a proposal, the proposal’s state is FINALIZED, and the proposal's deals become eligible to start serving based on their configurations.

The following sample demonstrates how you can accept a proposal with the accept method.

Cancel negotiation

You can use the buyers.proposals.cancelNegotiation method to cancel negotiation for a given proposal.

If you cancel a proposal that has never been finalized, its state is set to TERMINATED, and negotiation with the publisher ends. If you cancel a proposal that has a previously finalized proposalRevision, the propopsal reverts to the last finalized proposalRevision instead of being terminated.

You can't cancel private auction deals with the Marketplace API. You can archive private auction deals in the Authorized Buyers Marketplace UI.

The following sample demonstrates how you can cancel negotiation for a proposal with the cancelNegotiation method.
