IAM policies for Amazon API Gateway

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 IAM Policies for integrated services and Service integration patterns.

Resources:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "execute-api:Invoke"
            ],
            "Resource": [
                "arn:[[region]]:[[accountId]]:*"
            ]
        }
    ]
}

The following code example shows a resource policy for calling API Gateway.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": "states.amazonaws.com"
            },
            "Action": "execute-api:Invoke",
            "Resource": "arn:aws:execute-api:<region>:<account-id>:<api-id>/<stage-name>/<HTTP-VERB>/<resource-path-specifier>",
            "Condition": {
                "StringEquals": {
                    "aws:SourceArn": [
                        "<SourceStateMachineArn>"
                    ]
                }
            }
        }
    ]
}
