A Proposal
represents a negotiation between a buyer and a publisher. Proposals contain one
or more deals.
Buyers and their clients can use the Authorized Buyers Marketplace UI to view
and negotiate proposals. A client’s access to features in the Authorized
Buyers Marketplace UI depends on the client's
role.
Only buyers can use the Marketplace API.
To learn more about clients, and how to configure access to the Authorized Buyers Marketplace UI for one of your clients, see clients and client users.
If the buyer field is populated in a Proposal, then the publisher is
negotiating directly with you. If client is populated, then the publisher is
negotiating with one of your clients. You can negotiate on behalf of your
buyer account, or any Client associated with your account.
