# WhatsApp With Wati In DialNexa

> Connect Wati to DialNexa and send WhatsApp session or template messages from voice AI workflows.

WhatsApp with Wati in DialNexa lets workflows and eligible integration actions send WhatsApp messages through a connected Wati account. Use it for reminders, confirmations, follow-ups, and template-based messages after a call or workflow branch.

<Tip>
  A WhatsApp template is only as useful as its parameters. Check the placeholders before the workflow checks them for you.
</Tip>

## Before You Begin

Connect and validate Wati, prepare a consented test number, and confirm any template is approved with the expected parameter count and broadcast name.
