Hi brian_smith,
When creating a new Twilio or Twilio-WhatsApp channel in Front, we generate a unique, secure webhook for incoming messages. This is unique for every channel created and you’ll use it when configuring WhatsApp senders’ webhook URLs:

We only set this webhook in Twilio’s configuration at the time of channel creation. If for some reason you’ve lost your webhook URL, please don’t use another channel’s webhook. Instead, contact support@front.com and we can provide it!
