Whatsapp with twilio rejects all templates with Invalid format error

Question

I created about 10 templates and all of them were rejected with the reason Invalid format: The template content has an invalid format. Submit another template with the correct format.

What should I do, how to understand what the problem is, I even used the template that Twilio itself offers

I even used the template that Twilio itself offers

Here are a few options I have tried:

1. "Your One-Time Password code for {{1}} application is {{2}}."
2. "Your login code for {{1}} is {{2}}"
3. "Your One-Time Password code for Statfluence application is {{2}}."
4. "Your One-Time Password code for {{1}} application is {{2}}."

Answer 1

I just tested it and these templates also gets rejected. Apparently Meta changed the requirements for the templates and you cannot end a template with a placeholder.

I tried a template that doesn't end with a placeholder and that worked:

Your One-Time Password code for {{1}} application is {{2}}.
Please enter it in the web application.
