What is wrong in my request body to the Amazon SES Api?

Question

I am a Salesforce developer, and recently I've been trying to integrate the AWS SES Api into my project. I have run into many issues along the way (you can follow here)

I have successfully managed to post to AWS SES and get emails sent however, when I try to send a request using the Templated email method I run into an issue.

JSON body

{
    "Content": {
        "Template": {
            "TemplateData": "{\"unsubscribe\":\"test\"}",
            "TemplateName": "Welcome_Email"
        }
    },
    "Destination": {
        "ToAddresses": [
            "<redacted email address>"
        ]
    },
    "FromEmailAddress": "<redacted email address>",
    "ReplyToAddresses": [
        "<redacted email address>"
    ]
}

When I send the request using this Body it responds with a Status 400 with a body of {"Message":null}

When I send an Email using the Simple method, it's successful and send the email

{
    "Content": {
        "Simple": {
            "Body": {
                "Html": {
                    "Charset": "UTF-8",
                    "Data": "Test"
                }
            },
            "Subject": {
                "Charset": "UTF-8",
                "Data": "Test"
            }
        }
    },
    "Destination": {
        "ToAddresses": [
            "<redacted email address>"
        ]
    },
    "FromEmailAddress": "<redacted email address>",
    "ReplyToAddresses": [
        "<redacted email address>"
    ]
}

Right now I am just going to create the html data and use the simple method but I would like to be able to use templates in the future.

Any help would be appreciated.

UPDATE:

Figured out the formatting of my JSON was wrong here

Incorrect:

"TemplateData": "{\"unsubscribe\":\"test\"}"

Correct:

"TemplateData": "{unsubscribe:test}"
