Any way to upload files to the NetSuite FILE CABINET via SuiteTalk?

you could look at https://github.com/creecedev/NetSuite-Tools-For-WebStorm for inspiration .NET Sln here also has an example for uploading a file https://www.netsuite.com/portal/developers/resources/suitetalk-sample-applications.shtml

We ended up building a RESTlet and wrote a C# app to call it that way. We needed to attach to records while adding it to file cabinet and that seems like the easiest way for us.

Ahhh ty @Shawn Talbert and @NS Admin

it is possible though? you shouldn't needed a secondary RESTlet or anything you can even just do through raw POST with XML in whatever language you prefer, you don't necessarily need to use particular C#/Java app

Yeah, if you just want it in the file cabinet, that is possible. Our use case needed it attached to an existing record, so there needed to be logic in code to handle those use cases.

Ahh, so it is possible natively? To use SOAP API maybe? What about with REST API? Possible to upload a file to the FILE CABINET?

yah just SOAP Api in whatever implementation you choose doesn't look like File is exposed in REST Api https://system.netsuite.com/help/helpcenter/en_US/APIs/REST_API_Browser/record/v1/2022.1/index.html

also, I see no reason you can't attach a file to a record using the SOAP api.

File and attach detail how soap webservices handle uploading files and attaching them
