Deeplink for Whatsapp

This is the link that I am using for deeplink
"whatsapp://send?phone="
The issue is that when I try to follow the link in browser, I can get the WhatsApp business as an option


but from the app, I don't have it as an option

Which app ? Is this an AppInventor question ?

the app that i have built

Try using this as the DataUri for ActivityStarter:
https://wa.me/
Note After slash You have to enter your phone number, With the country code ( without the + in the start)
Also if you want a default text for the user to send add ?text=YOUR_TEXT After The phone Number.

More details about this please
to clear my use is not for a single link I am using a crud with Google sheet which has a lot of data for users and each user has his own link, so my use is only clicking the link to send WhatsApp msg.

Thank you

Are you using the custonwebview extension? This has a feature for deep links and handles non http links better than the native webviewer.

Yes, I do use customwebview with deep link enabled
