Hi Community, is it possible to add additional data(hope to add server generated custom rich massages ) by nodejs server, between a chat implemented in a mobile app(both iOS & Android)?  
Could some one help me out?

Hi @asanka and welcome to the Sendbird Community!

You can send messages from your Node.js back-end ([Learn more in the docs here](https://sendbird.com/docs/chat/v3/platform-api/guides/messages#2-send-a-message)).

If you would like to differentiate these types of messages from other normal user messages, you can specify the `custom_type` or `data` fields when sending a message.

Then you have to display the message accordingly in your front-end (Android & iOS) by reading the `custom_type` or `data` field of each message before rendering.

Hope this helps.
