Hey @rajeev-fas ,
in general, if you upload any attachments, a note gets created where the respective file can also be found. That is btw also the case when you create attachments through a form upload.
To get to the file/s from the API, you have to go through the associated activities to find them. There is no to_object_type called attachments or something similar.
This might sound stupid, but maybe you’re currently filtering notes in the activities when looking at the record.
Now, it is hard for us to diagnose these things at a distance. So without any more information, it will be very hard for us to help you any further. For example: How are these attachments created in the first place?
Cheers,
Chriso
