# WhatsApp With Wati In DialNexa

> Configure WhatsApp with Wati in DialNexa for API key connection, session messages, approved templates, parameters, broadcast names, workflow actions, and invocation review.

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.
