All communication between the MODLR Gateway and the MODLR Instances are completed over the stateless RESTfull API. The requests are made by the Gateway service to each of the MODLR Instances. Developers each have full access to this API and can make requests of their MODLR Instances.
The MODLR Gateway service Includes a page called the API Sandbox https://go.modlr.co/sandbox/ which provides a full list of API functions, descriptions and required arguments for use. This page allows API calls to be directly made against the MODLR Instance.
The API is available with 5 endpoints.
