GET /trade-api/v2/communications/quotes → behaviour change

Kalshi API

Stopped working

On June 20, 2026, the GET /trade-api/v2/communications/quotes endpoint dropped support for filtering by market_ticker or event_ticker. Calls that continue using query parameter market_ticker fail. Requests can no longer use these parameters to narrow down quote communications.

Calls it hits

  • GET /trade-api/v2/communications/quotes
  • query parameter market_ticker

What to use instead of these calls

Update your calls to filter quotes by user, RFQ, status, or update time instead.

In Kalshi API's words

GET /trade-api/v2/communications/quotes no longer supports filtering by market_ticker or event_ticker, effective immediately. Requests should filter quotes by user, RFQ, status, or update time instead.
