Connecting WhatsApp

Go to Apps → Caro → Support Channels → Add a channel → WhatsApp. This is the most involved of the three channel setups, since WhatsApp Business requires its own Meta Business infrastructure that isn't something Caro can create for you.

Connect WhatsApp dialog with Phone Number ID and Reply mode highlighted

What you need before you start

  • A Meta Developer app
  • A WhatsApp Business Account
  • A registered phone number
  • A permanent access token and your App Secret, generated from that Meta setup

If you don't have these yet, use the "Full WhatsApp setup guide →" link in the dialog (vosaire.com/docs/whatsapp-channel), or the "schedule a call with support" link to get help setting it up directly.

Filling in the form

FieldWhere it comes from
Phone Number IDYour WhatsApp Business Account's registered number, from Meta
Access TokenThe permanent access token you generated in your Meta app
App SecretUsed to verify inbound webhooks are really coming from Meta

Reply mode

Choose how Caro's replies actually get sent:

  • Auto-reply — sends AI replies immediately, with no human step in between.
  • Draft — a teammate reviews the reply before it sends.

For a brand-new WhatsApp connection, Draft is the safer starting point until you've confirmed Caro's replies are reliably accurate on this channel; switch to Auto-reply once you're confident.

One more step after connecting

The dialog warns that after you click Connect, you'll need to go back to your Meta App Dashboard one more time to paste in a webhook URL and verification token that Caro generates — the next step will show you exactly what to paste where.
