# Start an AWS Glue job with Step Functions
<a name="connect-glue"></a>

Learn to use Step Functions to start a job run on AWS Glue. This page lists the supported API actions and provides an example `Task` state to start a AWS Glue job.

To learn about integrating with AWS services in Step Functions, see [Integrating services](integrate-services.md) and [Passing parameters to a service API in Step Functions](connect-parameters.md).

**Key features of Optimized AWS Glue integration**  
The [Run a Job (.sync)](connect-to-resource.md#connect-sync) integration pattern is available.
The `JobName` field is extracted from the request and inserted into the response, which normally only contains `JobRunID`.

The following includes a `Task` state that starts an AWS Glue job.

```
"Glue StartJobRun": {
      "Type": "Task",
      "Resource": "arn:aws:states:::glue:startJobRun.sync",
      "Arguments": {
        "JobName": "GlueJob-JTrRO5l98qMG"
      },
      "Next": "ValidateOutput"
    },
```

**Parameters in Step Functions are expressed in PascalCase**  
Even if the native service API is in camelCase, for example the API action `startSyncExecution`, you specify parameters in PascalCase, such as: `StateMachineArn`.

## IAM policies for calling AWS Glue
<a name="glue-iam"></a>

The following example templates show how AWS Step Functions generates IAM policies based on the resources in your state machine definition. For more information, see [How Step Functions generates IAM policies for integrated services](service-integration-iam-templates.md) and [Discover service integration patterns in Step Functions](connect-to-resource.md).

AWS Glue does not have resource-based control.
