Steps Apply to Toast's Partner Integrations program and complete certification to be listed as a loyalty provider Host a REST endpoint that Toast's POS calls directly at checkout, distinguishing request types via the Toast-Transaction-Type header Validate incoming requests using Toast's authentication method (JWT validated against a published public key, or the newer static API key auth) Return loyalty account lookup, points balance, and reward-eligibility data within Toast's required low-latency response window Handle award/redemption transaction types and confirm them back to Toast synchronously Known gotchas The integration direction is inverted from most loyalty APIs — Toast's POS calls your endpoint, you don't call Toast to push points Checkout blocks on your response, so slow or failed responses directly disrupt the guest checkout flow The JWT-based auth method is marked deprecated in favor of static API key auth — confirm which your certification uses
