I want to add inline images to my transactional email templates. I can't find on the official API a way to push attachments for a template.
I've tested with the following parameters :
{
"ContentType": "image/png",
"Filename": "image.png",
"Base64Content": "base64code"
}
The API doesn't recognize the property : Properties not supported in JSON payload
I don't to attach my image each time I send the email using Send API.
Is there any way to attach files to a Mailjet Template.
