Learn about API Playground - a GraphQL client you can use to explore your GraphQL API's schema and also execute GraphQL operations.
- what is API Playground and what are its main features
Overview
By default, the Webiny Admin Area application includes a tool called API Playground.
In short, the tool represents a simple GraphQL client which you can use to:

Accessing API PlaygroundDefault GraphQL APIs
By default, when you open the API Playground, you get to interact with four different GraphQL APIs.
Main API
This is the main GraphQL API, which is being utilized by all of the default Webiny applications, for example Page Builder, Headless CMS, File Manager, and so on. Of course, the GraphQL API can be extended on your behalf, if need be.
Headless CMS (Read, Preview, Manage)
The API Playground can also be used to access all three Headless CMS GraphQL API types. These GraphQL APIs can also be extended on your behalf, if need be.

The API Playground automatically performs all of the GraphQL operations as you - the currently logged in identity (user).
