The Unit21 API enables you to integrate your systems with our services. Our API follows the REST convention and accepts and returns JSON data.
All requests should use the appropriate API URL which can be found at:
- Production: https://api.unit21.com
- Sandbox 1: https://sandbox1-api.unit21.com
- Sandbox 2: https://sandbox2-api.unit21.com
All API requests must be made over HTTPS; calls made over plain HTTP will fail. API requests without authentication will also fail - see the Authentication section for information on correctly authenticating calls to the Unit21 API.
