What is GraphQL?
GraphQL is a query language for your API, and a server-side runtime for executing queries by using a type system you define for your data. Unlike REST, GraphQL allows clients to request exactly the data they need, making it highly efficient and flexible.
Key Features of Our Client
- Schema Explorer: Automatically fetch and navigate the GraphQL schema to understand available queries, mutations, and types.
- Query Editor: Write and execute GraphQL queries, mutations, and subscriptions with ease.
- Variables Support: Pass dynamic variables to your queries using the built-in JSON variables editor.
Why Use a Dedicated Client?
Testing GraphQL APIs requires specialized tools that understand the schema and can handle complex queries and variables. Our online client provides a complete environment for interacting with any GraphQL endpoint directly from your browser, without needing to install desktop software.
Advanced Capabilities
- Subscriptions: Support for real-time data updates via GraphQL subscriptions over WebSockets.
- Custom Headers: Add authentication tokens or custom headers required by your API.
- Response Formatting: View formatted JSON responses with syntax highlighting for easy reading and debugging.
