Hi Sumit,
MQTT in Cumulocity is mainly designed for upstream messages. Only Operations can be handled downstream (on devices) per default. You can define own SmartREST Templates to retrieve data but also this is limited on Inventory or Operations: [SmartREST - Cumulocity IoT Guides](https://cumulocity.com/guides/reference/smartrest-two/#querying-data-from-the-device-object)
Anything else is bound to the REST API but needs internal ID handling.
Can you describe your use case? What kind of data do you want to pull?

Hi Sumit,
if it is about sending a String/JSON to a device, the [Shell command](https://cumulocity.com/guides/reference/device-management-library/#reference) might fit best in this case. It already comes with a built-in SmartREST template. You just need to subscribe to the topic `s/ds` for your device to receive a shell operation.
You need to first announce the capabilities of your device to Cumulocity as described in the [guide](https://cumulocity.com/guides/reference/device-management-library/#announcing-capabilities). This means, you need to tell Cumulocity that your device actually supports shell command operations. You can use the static template `114` for this to publish a message on the topic `s/us`. For example: `114,c8y_Command`.
Once you have done this, the Shell tab should appear for your device.
You can also follow the discussion [here](https://community.cumulocity.com/t/how-to-send-write-data-to-a-point-device-from-cumuloicty/4076) as it is the same topic.
Best regards
Christian
