# CloudIO REST API playground

CloudIO Platform offers two REST API playgrounds for the developers to make REST API calls.

The first API playground can be accessed via a URI/api for making guided REST API calls. It offers a simple UI for the developer to select a data source and enter the parameter values for performing the REST API calls. The system automatically generates the REST payload in real-time.

The second API playground can be accessed via a URI /jsontest for testing the APIs with a given REST payload. In addition to this, it offers a simple solution for load testing of the REST APIs.
