Chatwoot SDK

A Kotlin Multiplatform chat SDK for Chatwoot — one Compose chat page that runs natively on Android and iOS, backed by the Chatwoot website-widget API with live messages over websocket.

ChatPage(
show = showChat,
onFinish = { showChat =false },
styleConfig =DefaultStyle, // optional theming
)

Install

Android / KMP (Maven Central):

implementation("com.chatwoot.android:sdk:0.1.0")

iOS (Swift Package Manager): add this repo as a package dependency — the ChatwootSDK binary target ships as an XCFramework attached to GitHub releases.

Setup

Create a website inbox in your Chatwoot dashboard, then configure the SDK once at startup:

Chatwoot.configure(
baseUrl ="https://app.chatwoot.com", // or your self-hosted URL
websiteToken ="<website inbox token>",
)

Or declare it statically instead:

• Android — manifest <meta-data>: com.chatwoot.android.BASE_URL and com.chatwoot.android.WEBSITE_TOKEN
• iOS — Info.plist keys: ChatwootBaseUrl and ChatwootWebsiteToken

Then show the chat. On Android/Compose, call ChatPage (above). From Swift:

ChatPageViewControllerKt.ChatPageViewController(
onFinish:{ /* dismiss */ },
styleConfig:StyleConfigKt.DefaultStyle
)

Everything else — anonymous contact creation, conversation persistence across launches, history, live agent replies, typing indicators, reconnection — is handled inside.

Permissions (voice notes)

Recording a voice note needs the microphone. The SDK requests it at first use and silently hides the mic button if it's unavailable.

• Android — RECORD_AUDIO is declared in the SDK manifest and merges into your app automatically; nothing to add.
• iOS — you must add NSMicrophoneUsageDescription (with a user-facing reason) to your app's Info.plist. iOS aborts at permission-request time if the key is missing, and the SDK cannot supply it on your behalf.

Picking image/video/file attachments needs no runtime permission on either platform.

Identifying the visitor

By default the contact is anonymous. If your app knows who the user is, identify them so agents see a named contact and conversations follow the user across reinstalls/devices. Call it any time (typically after your own login), before or while ChatPage is shown:

Chatwoot.setUser(
identifier ="your-user-id", // stable id; recognises the same person later
name ="Ada Lovelace",
email ="ada@example.com",
phoneNumber ="+15551234567",
customAttributes =mapOf("plan" to "pro"),
identifierHash = serverComputedHash, // only if the inbox enforces identity validation
)
Chatwoot.setCustomAttributes(mapOf("plan" to "enterprise")) // merge more attributes laterChatwoot.reset() // on logout — forgets the session

Identity validation (optional): if you enable it on the inbox, identifierHash is required. It must be computed on your backend as HMAC-SHA256(hmacToken, identifier) — the HMAC token is a secret and must never ship inside the app. Passing a different identifier than the active session starts a fresh contact + conversation on the next ChatPage open.

Theming

All visual customisation flows through one object:

ChatPage(show, onFinish, styleConfig =DefaultStyle.copy(
primaryColor =Color(0xFF7C3AED),
title ="Support",
))
