API Data Schema

  • 5

Most GraphQL applications can automatically retrieve the schema via introspection and offer the following features:

  • Automatic completion for fields and arguments
  • Inline documentation for all available queries and fields
  • Validation of queries before requests are sent

Tools such as Postman, Bruno, Insomnia, and many GraphQL IDEs support this by default and display the schema documentation directly within their interfaces.
