Step Function to Send Email on Error/Success

Question

Dear Sir/Madam,

We have a couple of Step Functions running on a weekly basis, and we would like to know right after a Step Function encounter an error. Hence  we place a "Send Email" Task (Amazon Pin Point Email Service) before the fail State.All the main task's  error handling will Catch any error and continue the the "Send Email" State before failing the Step Function.

in side the "Send Email" configuration,  there is one API Parameters field, and i filled it in with :

```
{
  "Content": {
    "Body": {
      "Text": {
        "Data": "ERROR"
      }
    },
    "Subject": {
      "Data": "ERROR"
    }
  },
  "Source": "source@me.com",
  "Destination": {
    "ToAddresses": [
      "notify@me.com"
    ]
  }
}
```

However, when i try to save the state machine, i got an error saying:
`The field "Body" is not supported by Step Functions`
It seems like i dont know what need to be fill inside the API Parameters for Send Email task, unfortunately i cant find any reference for it.

May i ask where to read up or refer for Step Function Send Email?

Answer

If you want to get a notification on the Step Function execution failure (or even successful runs), you can setup a CloudWatch rule to monitor the execution status and then set the target as SNS topic to send an email when the rule is triggered.

Hi, Good Question

You could probably refer to https://github.com/aws-samples/aws-step-functions-notification-workflow for Step Function to Send Email on Error/Success using Lambda (https://github.com/aws-samples/aws-step-functions-notification-workflow/blob/master/src/lambda/SendEmailNotification.zip)

Answer

You need to follow the structure of SES API V2 https://docs.aws.amazon.com/ses/latest/APIReference-V2/API_SendEmail.html

In your case you are sending a `Simple` email:
```
{
    "Content": {
        "Simple": {
            "Body": {
                "Text": {
                    "Data": "ERROR"
                }
            },
            "Subject": {
                "Data": "ERROR"
            }
        }
    },
    "Source": "source@me.com",
    "Destination": {
        "ToAddresses": [
            "notify@me.com"
        ]
    }
}
```

I ran into this today. The SES API V2 endpoint for state machines seems broken; I couldn't add Destination, which makes it pointless.  I messed around with the GUI builder and could generate *something* that worked from a step using ses v1.

```
  "SendEmail": {
    "Type": "Task",
    "Resource": "arn:aws:states:::aws-sdk:ses:sendEmail",
    "Next": "Failure",
    "Parameters": {
      "Source": "from-email",
      "Message": {
        "Body": {
          "Text": {
            "Data": "text"
          }
        },
        "Subject": {
          "Data": "subject"
        }
      },
      "Destination": {
        "ToAddresses": []
      }
    }
  }
```
