  title: Adopets External payment-request Payment Transaction API
  version: '1.0'
  description: Adopets External API for organization (shelter/rescue) integrations. It lets an external partner system connect a staff user, then create and manage adoption-related payment requests and their transactions (adoption fees, licenses, products), including retrieving, changing, cancelling requests and refunding transactions. All operations are HTTP POST with a JSON body and use an organization API key (x-api-key) plus a per-session bearer token obtained from system-auth/connect. Derived from the provider's public Postman documentation; request/response shapes reflect the published examples.
