2026-05-24

Section titled “2026-05-24”

Notifications

Section titled “Notifications”
  • GET /v3/bidder/notifications + PUT /v3/bidder/notifications/read-all shipped (HAN-1881). Paginated notifications list with a limit=0 count-only mode for badge polling. Instagram-style bulk mark-as-read. Whitelabel-gated. See Notifications endpoint reference.

2026-05-23

Section titled “2026-05-23”

Auction GUID for realtime

Section titled “Auction GUID for realtime”
  • Every V3 response that surfaces an auction now carries guid (auction-shape responses) or auctionGuid (item-shape responses). Clients use {guid}_v2 as the Socket.IO room name to receive auction-scoped events. HAN-1878.
Section titled “Featured items backfill”
  • featuredItems[] on auction cards now always returns up to 4 items. Manager-curated items come first; backfill items follow, ranked by validated bid count. Affects /v3/auctions, /v3/auctions/{id}, /v3/auction/{id}/items, /v3/bidder/my-auctions. HAN-1877.

2026-05-22

Section titled “2026-05-22”

Real rate limiter

Section titled “Real rate limiter”
  • The previously-stubbed V3RestController::enforceRateLimit() is now a real fixed-window throttle. Per-endpoint budgets, IP-keyed anonymous, userId-keyed authenticated. Over-budget responses return 429 with both a Retry-After header and a retryAfter body field. See Rate limiting. HAN-1867.

Favorites DELETE 405 fix

Section titled “Favorites DELETE 405 fix”
  • DELETE /v3/bidder/favorite/{itemId} was returning 405 due to a verbs() map gap. Fixed; the endpoint works as documented. HAN-1876.

2026-05-19

Section titled “2026-05-19”

V3 favorites write endpoints

Section titled “V3 favorites write endpoints”
  • POST /v3/bidder/favorite/{itemId} + DELETE /v3/bidder/favorite/{itemId} shipped. Idempotent on both verbs. HAN-1864.
