Amazon API Gateway

These example templates show how Amazon Step Functions generates IAM policies based on the resources in your state machine definition. For more information, see:

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>"
                    ]
                }
            }
        }
    ]
}
