Can I write my own OTP message text?

No. Authentication templates use Meta's fixed text. You can only add the security line, expiry time and button.

What is the difference between copy code and one-tap?

Copy code lets the user copy the OTP. One-tap autofills it in your Android app and needs your app's package name and signature hash.

The copy-code button needs the same code so it can copy it for the user.

Yes. Create an authentication template in WATick and send it through the API from your app.

Authentication templates use a fixed format set by Meta – you can't write your own body text.
