WhatsApp one-time code verification (OTP)
Send a 6-digit code over WhatsApp and verify it afterwards: two ready-made webhooks to validate your users phone numbers.
Everything is created inactive in a new folder of your account. Nothing runs until you activate it, and you can undo it for 24 hours.
What it does
Two workflows that together implement a one-time code verification. Request code receives a phone number, generates a random 6-digit code, stores it in a Data Store with a 5-minute expiry and sends it over WhatsApp. Verify code receives the phone and the code typed by the user, checks it exists and has not expired, deletes it so it cannot be reused and answers verified: true or verified: false.
What you need: a WhatsApp Business Cloud API account (token and phoneNumberId). Outside the 24-hour conversation window WhatsApp requires an approved template; if that is your case, swap the node for WA Send Template.
How to use it: install the template, connect WhatsApp and call both webhooks from your website or app.
Note: expired codes that nobody verifies stay in the otp Data Store; you can clean them up periodically.
