You can find the Roezan API docs at the link below:

Roezan API Documentation (SwaggerHub)

Note on SwaggerHub:

SwaggerHub is primarily only for documentation purposes. 

Swaggerhub allows you to test the calls directly in the browser, but we recommend testing with Postman.

Swaggerhub API urls will provide dummy data. For your real account data, you'll want to use the Roezan live API address (https://app.roezan.com/api).
