Introduction to the API

Here’s a brief introduction to iugu's APIs.

iugu offers a web programming interface in the REST model, allowing efficient interaction with its system. With this API, you can execute commands, check configurations, and synchronize data with your own systems.

Communication is done through the base address https://api.iugu.com, always using the secure protocol https://. API versions are organized into specific directories, appended to the base address (e.g., https://api.iugu.com/v1).

Postman Collection

In addition to references at dev.iugu.com/reference, we provide a Postman Collection (for now, on PT-BR version):

Authentication

Authentication in iugu is performed via an API key, which allows the system to identify your account and grant the necessary permissions to communicate with iugu on behalf of the associated account. Learn more.

Production and Testing

The distinction between a production or testing environment is made through the api_token used during the request. Create an api_token and use it as needed.

🚧

Warning

The test endpoint is subject to a usage limit of 50 requests per minute. Requests that exceed this limit will receive a response with the HTTP 429 - Too Many Requests status code.

We recommend using Mocks in automated tests to avoid restrictions and ensure greater control over your validation flows. Learn more.
