Difference between template key and template alias | Zoho ZeptoMail FAQ

What is the difference between template key and template alias?

Template key: The template key is a unique identifier assigned to each template created in ZeptoMail. It is available next to the templates in the Templates section within an Agent. This key can be passed as a parameter in the API request body to use a specific template.

Template alias: The template alias is a user-defined name for a template for quick reference. This helps them easily use the desired templates in API calls instead of copying and pasting the template key every time. 

Alert
You can use either the template key or template alias and not both.
