# Loyalty auto-apply

Auto-apply loyalty cards to Revolut-card transactions. Revolut sends the partner-issued
membership and program identifiers recorded during enrolment or linking, together with the
transaction context you use to match the purchase. Revolut uses the merchant ID and
acquiring institution ID you provide during onboarding to route eligible transactions. The
acquiring institution ID is routing data and is not included in the callback request.
