# Apps on Saleschat

## What are External Apps?

External Apps let you send one-way messages to your leads through SalesChat from any external system — your CRM, marketing automation platform, notification service, or custom backend.

**Use cases:**

* Fyno / CleverTap / WebEngage sending campaign messages through SalesChat
* Your CRM triggering a follow-up template when a deal stage changes
* A custom backend sending appointment reminders or payment confirmations

**What External Apps can do:**

* Unified inbox — Messages sent from Fyno, CleverTap, or any external platform appear in the same agent inbox alongside regular conversations.
* Instant lead response — When a customer replies to a campaign or notification message, your sales agent sees it immediately and can respond in real-time. No switching between tools.
* Consistent customer experience — Whether a message originates from your CRM, notification platform, or SalesChat itself, the customer always sees it coming from your single WhatsApp business number.
* Audit trail — Every message sent through external apps is tracked with delivery status.
* The message appears in the chatroom as sent by the app's bot user, so agents can see it in context alongside their own messages.

> **Do I need to manage contact and chatroom?**\
> No. Contact and Chatroom are automatically resolved internally by Saleschat.
