Gateway Ticketing System Integration with Digital Membership Card System using API

Hello everyone, We are working on an integration between the Gateway Ticketing System and a digital membership card software (Membership Anywhere) to improve member access and verification. The main goal is to use an API-based integration, possibly via Swagger/OpenAPI, so that member details can sync in real-time and digital membership cards can be validated directly during ticket scanning or entry. We would like to understand whether Gateway Ticketing System provides REST APIs suitable for this type of integration, and whether Swagger/OpenAPI definitions can be effectively used to support membership card validation workflows. We are also interested in best practices for securely syncing member data between ticketing and membership systems, along with any limitations or challenges that may arise in real-time API-based access control integration. If anyone has experience working on similar integrations, your guidance would be greatly appreciated.
