Welcome to the API for Paperless Transactions. We offer two tools for developer support and documentation. For additional support, please contact support@paperlesstrans.com or visit our Online Help Center.

Before testing, you will first need to obtain a "Terminal Key". To receive a demo Terminal Key, please contact support@paperlesstrans.com.


Swagger is the world’s largest framework of API developer tools for the OpenAPI Specification(OAS). Swagger UI allows you to visualize and interact with our API’s resources while providing visual documentation of the end point specfications.


Our TestClient tool allows you to build, analyze and send requests to our API endpoints and view the responses in your browser. Use the Request Builder feature to build your requests in a "wizard-like" interface. You can also save requests to your browser's local storage for ongoing testing.
