Postman

Postman has support for GraphQL as well. In the standalone client, there are two different ways that GraphQL can be used:

• REST request with a GraphQL body
• GraphQL request

Using GraphQL request allows for discovery of the api. No knowledge about the schema is needed; instead the input and output to the request can be chosen in the UI, but this works only when running against a local api since it currently cannot authorize with the server.
