Run the introspection query to map out all methods
Use GraphQL Voyager to display all methods
Use BatchQL or the InQL extension to test all methods for IDORs, SQLi, SSRF, etc
Definition
Query is an operation to retrieve data (read).
Mutation is an operation used to submit and write data (create, update, and delete).
Subscription is an operation used to send data (read) when an event occurs. Subscription is a way for GraphQL clients to listen to live updates from the server.
