ExaChat Overview

Real-time customer and in-app messaging from one product. Use the embeddable Live Chat widget for customer support on your website, the In-App Chat SDK to build messaging inside your own app, or both — they share the same real-time engine.

Embeddable Widget

Add a premium, customizable chat widget to any website with a single line of code.

Agent Management

Route conversations to specialized agents or support teams based on workload.

In-App SDK

1:1, group, and broadcast channels inside your own mobile or web app, with the same real-time engine.

Presence & Typing

Online/offline/away state and ephemeral typing indicators, synced in real time across clients.

AI Integration

Connect your custom AI models to handle initial customer queries automatically.

Webhooks

Server-side events for messages, agent assignment, and channel/member changes on both surfaces.

Authentication

All REST requests use HTTP Basic Auth with your dashboard Base64 token: Authorization: Basic <token>. Auth guide →

Two ways to integrate

Live Chat and the In-App Chat SDK are separate integration surfaces under the same ExaChat product — pick the one that matches your use case, or use both. They don't share conversations/channels with each other.

Live Chat Widget

The fastest way to get started — a customer-support chat widget you embed on your website, backed by a REST API and webhooks for agent routing.

Widget Setup

Drop-in script tag to enable chat on your website instantly.

Start Conversation

Open a new conversation from the REST API.

Send Message

Send messages into an active conversation.

Conversations

List, fetch, and manage conversation state.

Agents & Routing

Assign conversations to agents and support teams.

Webhooks

Real-time conversation and message events.

In-App Chat SDK

Closed-loop 1:1, group, and broadcast messaging inside your own mobile or web app. Your server mints short-lived user tokens; the client SDK handles connect, send, presence, and typing.

Which one do I need?

Live Chat

You want a support widget on your marketing site or dashboard where visitors chat with your agents — minimal integration work, no client SDK to ship.

In-App SDK

You're building messaging as a feature of your own product (marketplace DMs, group chat, broadcast channels) and need full control over the UI via the client SDK.
