An update proposal is a pending change to a media buy that awaits resolution by the sales agent. It moves from PENDING to either APPROVED or REJECTED. While a proposal is PENDING, you can poll its status or cancel it; once resolved, it is terminal. Poll the proposal until status leaves PENDING. When a proposal is REJECTED, read rejectionReason for the cause. To withdraw a change before the agent acts, cancel it. All requests use the base URL https://api.interchange.io/api/v2/buyer and a Authorization: Bearer $SCOPE3_API_KEY header.
