Hello @narendar

Thanks for sharing your issue with the community.

Now, a 400 error means that either the endpoint or body is malformed and so not compatible with the Ubidots’ API. In that sense, can you please share the code lines where you connect to the server and build the payload? It’s likely that the error might be in any of those lines.
