# GraphQL - Workflow node | Docs - nodulz

Source: https://nodulz.com/docs/nodes/graphql

Language: en

Execute GraphQL queries and mutations with variables.

## Usage and specifics

Configure a compatible credential and service query or operation. Response shape depends on the service; inspect it before mapping. Account permissions apply to reads and writes.

Technical type : `graphql`. Runtime : `nodulz`.

## Credentials and prerequisites

- [GraphQL](/docs/credentials) (`integration` / `graphql`). Bearer token for a GraphQL API. Set the URL in the node.

Create credentials in your nodulz instance’s Credentials area, then select them on the node. Availability depends on ownership and sharing. See the [credentials guide](/docs/credentials) for access and rotation.

## Parameters

Names below are technical keys. Defaults are not a ready-to-run configuration: complete fields required by your operation. Paths containing [] describe list items; some fields depend on the selected mode.

| Parameter | Type | Default | Values / limits |
| --- | --- | --- | --- |
| `credentialId` | `string` | `""` | - |
| `endpoint` | `string` | `""` | - |
| `query` | `string` | `"query { __typename }"` | - |
| `variables` | `string` | `"{}"` | - |
| `operationName` | `string` | `""` | - |
| `failOnErrors` | `boolean` | `true` | - |
| `timeout` | `number` | `30` | -; ≥ 1, ≤ 600 |

## Configuration help

| Setting | Purpose and guidance |
| --- | --- |
| `timeout`<br>Timeout (seconds) | Between 1 and 600 seconds. Cancellation interrupts the running request. |
| `failOnErrors`<br>Fail on GraphQL errors | Also fails on HTTP 200 responses containing errors. Disable to handle partial data and errors in the output. |

## Initial configuration

Initial catalog configuration example, to adapt before running. Keep secrets in credentials.

```json
{
  "credentialId": "",
  "endpoint": "",
  "query": "query { __typename }",
  "variables": "{}",
  "operationName": "",
  "failOnErrors": true,
  "timeout": 30
}
```

## Verification

Test with representative data. Check node output in the inspector and logs, then use editor mapping for downstream fields. A trigger test with a simulated payload does not validate external service delivery.
