This response has no body data.
Make sure to provide values for all your custom placeholders when sending the email. If any placeholder is missing a value, the send API will return an error. Supported system placeholders:
  • {{ sys.first_name }}: the user’s first name from their profile.
System placeholders (like {{ sys.first_name }}) are automatically filled in by the system using the user’s profile data. For example, “Hi {{ sys.first_name }}” will become “Hi John” when sent to a user named John.
Here’s an example of a JSON object with all the placeholders used in an email template. Subject: 
Welcome to {{ platform_name }}!
Body: 
Hi {{ user_name }},
