Authentication templates 🔒

You can now create and send authentication templates directly from Callbell.

These templates follow Meta's standard format and are ideal for sending one-time passwords (OTPs) to your customers.

What's included:

  • Optional security disclaimer

  • Optional expiration warning

  • Two delivery options: a Copy Code button and a One-Tap button (Android only)

If you have a WhatsApp Cloud API number with Callbell, feel free to create your authentication templates at https://dash.callbell.eu/settings/whatsapp_templates
