# Update proposal tasks

> Per-operation reference for the buyer update proposal API

Each page below documents a single update proposal operation — request, parameters, response shape, and errors. Poll a proposal until it leaves `PENDING`, or cancel it before the sales agent resolves it. For the model, see the [Update proposals overview](/v2/buyer/update-proposals/overview).
