GraphQL

GraphQL is a supported request type in Requesto. Write queries or mutations in a dedicated editor, send variables separately, fetch the endpoint schema for IntelliSense, and browse schema documentation without leaving the request.

Creating a GraphQL Request

Create a request from a collection or switch an open request using the request picker beside the URL.

The picker keeps HTTP methods and GraphQL transports together:

• GQL POST sends a JSON request body and supports queries and mutations.
• GQL GET sends the query and variables as URL parameters and supports queries only.

Enter the GraphQL endpoint, open Query, and write one operation.

One operation per request

Requesto supports exactly one GraphQL operation in each request. If the document contains multiple operations, the editor shows a warning and the request is not sent. Split each operation into its own saved request instead.

Query Variables

Define variables in the query, then provide their values as a JSON object in the Variables tab. Keep environment placeholders in the Variables tab rather than inserting them directly into the GraphQL document.

query GetUser($id: ID!) {
  user(id: $id) {
    id
    name
    email
    role
  }
}

{
  "id": "{{userId}}"
}

In this example, userId comes from the active environment. Requesto resolves the placeholder when the request is sent, while $id keeps the query valid GraphQL and preserves schema-aware completion and diagnostics.

Use the same pattern for queries and mutations:

1. Declare a GraphQL variable such as $id or $input in the operation.
2. Use that variable in the query or mutation fields.
3. Assign an environment placeholder such as {{userId}} in the Variables JSON or enter just enter a regular value.

The variables value must be a JSON object. Arrays and other top-level JSON values are rejected before the request is sent.

Fetching a Schema

Select the refresh icon beside the endpoint to run GraphQL introspection. Requesto uses the request's headers and authentication settings, including OAuth, API keys, bearer tokens, and active environment variables.

After a schema loads, the Query editor provides:

• Field and argument completion
• Type information
• Hover documentation
• Schema-aware diagnostics

Saved GraphQL requests fetch their schema automatically when opened. Unsaved requests remain manual so typing a draft endpoint does not trigger network traffic.

Use the book icon beside the endpoint to open the schema explorer.

The explorer includes query, mutation, and subscription root types when present, plus object fields, arguments, enums, unions, descriptions, and deprecation information. Search by type name or follow a return type to navigate through the schema.

Schema Profiles

Schema profiles let multiple requests share a schema source. Open the schema explorer and select New profile.

Source	Use case
Endpoint introspection	Fetch a live schema from a GraphQL endpoint
GraphQL SDL	Paste or import a .graphql, .graphqls, or .gql schema
Introspection JSON	Paste or import an introspection result from another tool or schema registry

A request linked to an endpoint profile loads the last local cache immediately, then refreshes it in the background. Editing a profile's source invalidates the old cache.

Storage and privacy

Requesto separates shareable schema configuration from generated endpoint data:

• Profile names, source URLs, and user-provided SDL or JSON are stored in .requesto/graphql-schemas.json and can be committed with the workspace.
• Fetched introspection results are stored in .requesto/local/graphql-schema-cache.json, which stays local and should not be committed.
• Resolved authentication credentials and environment values are never written to a schema profile or cache.

Role-specific schemas

Some GraphQL servers return a different schema depending on the authenticated user. Refresh the schema after changing authentication or environment credentials.

Responses and Errors

GraphQL may return HTTP 200 while also returning field errors. Requesto inspects GraphQL response envelopes and distinguishes:

• Successful data
• GraphQL errors
• Partial responses containing both data and errors

When errors are present, the response panel adds an Errors tab with each message, response path, and source location. The original JSON response remains available in Body.

Authentication, Headers, and Environments

GraphQL requests reuse Requesto's existing request features:

• Configure credentials in Auth.
• Add custom values in Headers.
• Use {{variableName}} placeholders in the endpoint, headers, or variables JSON.
• Run pre-request scripts and tests normally.

For endpoint introspection, Requesto sends the same effective headers and authentication as the request.

Troubleshooting

Schema fetching returns 401 or 403

Confirm the request's Auth and Headers settings. Introspection uses the same authentication as the request. Some servers expose different schema fields to different roles.

Introspection is disabled

Create an SDL or Introspection JSON schema profile and link it to the request. Query execution does not require introspection.

A mutation cannot be sent with GQL GET

Mutations have side effects and cannot use the safe HTTP GET method. Switch the request picker to GQL POST.

IntelliSense disappears after changing tabs

IntelliSense is restored when the Query editor remounts. If no suggestions appear, refresh the schema and check the schema explorer for an introspection error.

The request contains multiple operations

Move each query or mutation into a separate request. Requesto intentionally does not choose between multiple operations in one document.
