Cognito CustomMessage_AdminCreateUser mandatory use of {username} in template

Question

I would like to use **email** or **preferred_username** in a template for *CustomMessage_AdminCreateUser*.

But it seems that Cognito requires that {username} must be present in a template, otherwise the default message is sent.

We cannot use "username" as we use this attribute to store uuid for a user. Including it in a message does not make sense.

Is there any way of preventing Cognito checking the presence of {username} in a template so the other attributes can be displayed as well?

Answer

Unfortunately, as you described, the username parameter is required. If it is missing, the default message template is used. A possible workaround is to use a HTML tags to hide the username value but this does not remove the username from the message. Again, a username parameter is required in the template.
