Hey @OmerGafny
Great post. I know its been a while since you post and Mautic has had a number of releases since then, I went ahead and followed your directions.
However I get a 401 error in the users log card:
I have checked and there are no errors in the mautic.error log or the mautic UI system log.
I went and built the same string using curl in terminal to check if I am able to reach the endpoint and am able to send the message of via WhatsApp.
Any ideas or other ways I can try debug.
