This is the official API hub for UnDosTres, where you’ll find everything you need to integrate with our platform efficiently and securely.

Our APIs follow RESTful principles, featuring clear and descriptive endpoints. They accept JSON-formatted request bodies and return JSON responses, while relying on standard HTTP methods, authentication mechanisms, and response codes. However, certain endpoints may require or return data in XML format, depending on the specific operation.

UnDosTres offers two environments to support your development process:

Production: the live environment used by our customers to perform real operations.
Sandbox: a safe, no-cost testing space where you can explore and simulate our APIs without affecting real data.

Nevertheless, only the Sandbox environment URL is necessary for the purposes of this documentation.
