@hossam For the use case you described, we recommend using our SDK. Typically, when you query channels with our API, they are sorted by ‘last active’ by default. Based on your use case, you will need to use real-time events, which our SDK supports as documented here: [Amity SDK - Realtime Events](https://docs.amity.co/amity-sdk/core-concepts/realtime-events).

Hello @hossam ,
To integrate ChatRealTime using our Chat SDK alongside your existing API for authentication, please follow these steps:
1. **Install the Chat SDK:** Refer to our [Installation and Authentication Guide](https://docs.amity.co/getting-started/installation-and-authentication) for detailed instructions on setting up the SDK.
2. **Set Up Authentication:** Ensure your authentication setup aligns with our API as detailed in the guide.
3. **Implement ChatRealTime:** For instructions on using real-time chat features, visit our [Chat SDK Documentation](https://docs.amity.co/amity-sdk/chat).

So Thank you for help , please can you provide me the steps after this
```auto
import { API_REGIONS, Client, enableCache } from '@amityco/ts-sdk';
const apiKey = 'b0e9ec5d3eddf5641f328d4a555b168ed20c8bb0bf356b7a';
const client = Client.createClient(apiKey, API_REGIONS.EU);
enableCache();
```
And when log the response in the SDK It return
```auto
{"accessTokenExpiryWatcher": [Function accessTokenExpiryWatcher], "apiKey": "b0e9ec5d3eddf5641f328d4a555b168ed20c8bb0bf356b7a", "cache": {"data": {}}, "emitter": {"all": Map {}, "emit": [Function emit], "off": [Function off], "on": [Function on]}, "getFeedSettings": [Function getFeedSettings], "getMarkerSyncConsistentMode": [Function getMarkerSyncConsistentMode], "getMessagePreviewSetting": [Function getMessagePreviewSetting], "getSocialSettings": [Function getSocialSettings], "hasPermission": [Function hasPermission$1], "http": [Function wrap], "isUnreadCountEnabled": false, "log": [Function print], "mqtt": {"connect": [Function connect], "connected": false, "disconnect": [Function disconnect], "off": [Function off], "on": [Function on], "once": [Function once], "removeAllListeners": [Function removeAllListeners], "subscribe": [Function subscribe], "unsubscribe": [Function unsubscribe]}, "sessionHandler": undefined, "sessionState": "notLoggedIn", "use": [Function use], "validateTexts": [Function validateTexts], "validateUrls": [Function validateUrls], "version": "v6.22.0-cjs", "ws": {"_callbacks": {"$connect": [Array], "$connecting": [Array], "$disconnect": [Array]}, "acks": {}, "connected": false, "disconnected": true, "flags": {}, "ids": 0, "io": {"_randomizationFactor": 0.5, "_reconnection": true, "_reconnectionAttempts": Infinity, "_reconnectionDelay": 2000, "_reconnectionDelayMax": 5000, "_timeout": 20000, "autoConnect": false, "backoff": [Backoff], "connecting": [Array], "decoder": [Decoder], "encoder": [Encoder], "encoding": false, "lastPing": null, "nsps": [Object], "opts": [Object], "packetBuffer": [Array], "readyState": "closed", "subs": [Array], "uri": "https://api.sg.amity.co"}, "json": [Circular], "nsp": "/", "receiveBuffer": [], "sendBuffer": []}}
```
But I want to connect with EU and I put this already so why?

I think you don’t answer my question I told you when I trying to connect to the SDK I got that
```auto
{"accessTokenExpiryWatcher": [Function accessTokenExpiryWatcher], "apiKey": "b0e9ec5d3eddf5641f328d4a555b168ed20c8bb0bf356b7a", "cache": {"data": {}}, "emitter": {"all": Map {}, "emit": [Function emit], "off": [Function off], "on": [Function on]}, "getFeedSettings": [Function getFeedSettings], "getMarkerSyncConsistentMode": [Function getMarkerSyncConsistentMode], "getMessagePreviewSetting": [Function getMessagePreviewSetting], "getSocialSettings": [Function getSocialSettings], "hasPermission": [Function hasPermission$1], "http": [Function wrap], "isUnreadCountEnabled": false, "log": [Function print], "mqtt": {"connect": [Function connect], "connected": false, "disconnect": [Function disconnect], "off": [Function off], "on": [Function on], "once": [Function once], "removeAllListeners": [Function removeAllListeners], "subscribe": [Function subscribe], "unsubscribe": [Function unsubscribe]}, "sessionHandler": undefined, "sessionState": "notLoggedIn", "use": [Function use], "validateTexts": [Function validateTexts], "validateUrls": [Function validateUrls], "version": "v6.22.0-cjs", "ws": {"_callbacks": {"$connect": [Array], "$connecting": [Array], "$disconnect": [Array]}, "acks": {}, "connected": false, "disconnected": true, "flags": {}, "ids": 0, "io": {"_randomizationFactor": 0.5, "_reconnection": true, "_reconnectionAttempts": Infinity, "_reconnectionDelay": 2000, "_reconnectionDelayMax": 5000, "_timeout": 20000, "autoConnect": false, "backoff": [Backoff], "connecting": [Array], "decoder": [Decoder], "encoder": [Encoder], "encoding": false, "lastPing": null, "nsps": [Object], "opts": [Object], "packetBuffer": [Array], "readyState": "closed", "subs": [Array], "uri": "https://api.sg.amity.co"}, "json": [Circular], "nsp": "/", "receiveBuffer": [], "sendBuffer": []}}
```

Hi hossam, Can you try login with this code? The login will be completely after you call `Client.login` and pass userId and displayName to the function
```auto
const client: Amity.Client = Client.createClient(apiKey, 'eu', {
apiEndpoint: { http: 'https://api.eu.amity.co' },
});
const handleConnect = async (userId: string, displayName: string) => {
const response = await Client.login(
{
userId: userId,
displayName: displayName
},
sessionHandler,
);
console.log('response:', response)
};
const sessionHandler: Amity.SessionHandler = {
sessionWillRenewAccessToken(renewal: Amity.AccessTokenRenewal) {
// for details on other renewal methods check session handler
renewal.renew();
},
};
```
