I’m developing an application similar to Confirmafy that uses the WhatsApp Business API to send messages to users. According to WhatsApp’s documentation, message templates need to be pre-approved, and line breaks are not allowed within variables.

However, I’ve noticed that Confirmafy allows users to edit the message body, including adding line breaks, and the message is sent instantly without any apparent approval process. Here’s an example of how the message configuration looks in Confirmafy

In this configuration, I can insert line breaks and any text, and the message is delivered instantly via WhatsApp. This behavior seems to contradict WhatsApp’s official documentation.

How does Confirmafy manage to send messages with line breaks in variables without needing pre-approval from WhatsApp?
Is there a specific API endpoint or method that bypasses the template approval process?
Are there any exceptions or special permissions required to achieve this functionality?

I already talked to Twilio and Meta support and they can´t help me. Someone know hoy can I do this? Thanks
