The function was requested almost immediately from the moment the function of checking the presence of WhatsApp on the number appeared. And finally we got there :)
The integration will check the existence of WhatsApp at the main contact of the transaction.
Based on the test:
1 trigger action option: change the switch of the field selected in the drop-down list.
2 trigger options:
Change the stage of the transaction after verification.
If there is a vatsap - change the stage of the transaction to another, or or leave the same
If there is no vatsap - change the stage of the transaction to another, or or leave the same
You can choose either both options for the trigger action, or one of them.

The widget has already been updated and these changes are available for work.

P.S. For WABA, this feature does not work, as WhatsApp detection is prohibited by Facebook and may lead to blocking FBM.
