GraphQL request
GraphQL APIs let clients request only the data they need through a single endpoint. It’s schema-driven, allowing clients to introspect and avoid overfetching or underfetching data. Each GraphQL request has a URL (the data endpoint) and a query (defining the data to retrieve or modify). The API schema defines available fields, and the request may include authentication, headers, and settings as needed. GraphQL requests support three operations:- Query: Retrieves data, specifying fields and optional arguments for precise results.
- Mutation: Modifies data (create, update, delete), with specified fields returned after the operation.
- Subscription: Provides real-time updates by listening for changes to specific data fields over a persistent connection.
