Profile Requirements

To deliver a message to a recipient over Mailjet, Courier must be provided the recipient’s email address. This value should be included in the recipient profile as email.

{
  "message": {
    // Recipient Profile
    "to": {
      "email": "example@example.com"
    }

    // ... rest of message definition
  }
}

​
Override

You can use a provider override to replace what we send to Mailjet’s Send API. For example, you can add an attachment to your request:

{
  "message": {
    "template": "ABCDEFGHIJKLMNOPQRSTUVWXYZ",
    "to": {
      "email": "example@example.com"
    },
    "providers": {
      "mailjet": {
        "override": {
          "body": {
            "Attachments": [
              {
                "ContentType": "text/plain",
                "Filename": "test.txt",
                "content": "VGhpcyBpcyB5b3VyIGF0dGFjaGVkIGZpbGUhISEK"
              }
            ]
          }
        }
      }
    }
  }
}

Everything inside of message.providers.mailjet.override will replace what we send to Mailjet’s Send API. You can see all the available options by visiting Mailjet API docs.
