Good morning to all of you. I need your invaluable help. Unfortunately I don't understand much about programming :-(
I would like to understand if it is possible through Google App Script to create the following:
I have a google spreadsheet where customers register by entering their phone number. At each new registration (each new line) the script automatically sends a whatsapp message to the customer indicating that the registration was successful.
I have TWILIO and its API as an active service. I have activated a specific number and everything is verified and working.
I ask for your help as I just don't know where to start. Thanks to everyone and I hope to receive your advice. Mauro
Update:
I'm trying to do it with ZAPIER also seeing a post created some time ago: How to send a whatsapp message through twilio via zapier webhook
But I have this error: The request could not be sent to Webhooks by Zapier. The app returned "A 'To' phone number is required.".
I have attached the image with the inserted configuration. Where did I go wrong? How should I correct it?
