# Changelog

Changes to the partner API (`/api/v1`) and the public endpoints. Within v1, fields are added but never removed or renamed.

<Update label="October 2026" description="v1">
  The first version of the partner API and these docs.

  * Campaigns fetch winners from your URL by default, or take them by `POST`.
  * Drawings are numbered 1, 2, 3 per campaign with no gaps, given when the random value is requested. `partnerRound` carries your own round number when Prizerail reads one from your source.
  * Proofs are `prizerail-draw-proof/2`: rolls start at 0, tiers run top prize first with thresholds, and the formulas match the Prizerail contract.
  * Guarantee periods are 30 days from the campaign's start, and paused time doesn't count.
