REST API create node with category is returning "Could not process object, invalid action 'create'"

OT does not accept Files like a share like you have shown <file>\\hoaadv3333\operations\Kofax\Export\00000504\1.pdf</file>

The proper way to send a file to CS is through a POST using multipart/form data thousands of examples exist in this forum. Find a JS example in this forum(read implementation notes specifically)

If I am not mistaken I shared a Java file in this forum as I had this same need and I found a POJO doing a file upload using multipart form data and I repurposed it. Sorry this forum is very difficult to search things so perhaps you can find a JS version and repurpose it for your coding language

re-reading I think you are sending it with the fake body but it is very susceptible to errors

here's a working Postman payload

in my blog https://appukili.wordpress.com/ I have put the java file I usually use I called it JAVA REST API EXPERIMENTS .docx the actual code file that i shared is called DocumentHelper.java I would see if that worked somehow as I think it is heavily commented

I need to move all of this resources to my own place as OT is retiring CS links

BTW I think you are almost right it may be the attribute name like file ,body etc so you can cross check with some of my code or stuff existing in this forum

The easiest method is JS search for @Ferdinand Prantl 's many many examples in this forum most of the times he puts out examples using JS and C# so it is quickly testable. He usually puts out why certain things have to be done that way as well :) or @Nizar Ghazal I had to go with POJO because for the life of me I did not know how to deploy high level REST packages in java in the application server I was working which was IBM WebSphere .

The path needs to be selectable (open /See in Windows) by POSTMAN control. If you think about it when you invoke Postman you are accessing it as the user on your logged-in computer so to upload a file you need access. To figure out your problem in classic GUI do an Add Item document use the control and select this file \\hoaadv3333\operations\Kofax\Export\00000504\1.pdf using the file selector, does it work? use the smartui and do the same that is what you are doing with the REST API.

If you store a path in a table that is a string…Livelink will accept only a File where FileName is the string…

but there are more properties to the file object than just a name.

I would check permissions to the file system rather than thinking it cannot be done😊

I trimmed our server and the file path but from the screencap, you can see that I am uploading a file that is in an azure file system…

BTW Vishnu when Postman sends a file that easily it is doing a multipart/form-data POST that is very hard for new-age developers to understand. What we all do now is use higher APIs like CURL,restsharp,java etc but all they are doing is still an HTTP POST.
