API testers struggle to automate file-upload requests
API testers and developers need to send files in requests and include uploads in repeatable tests, but the evidence describes gaps in configuring multipart requests and running file-upload tests from a GUI or script. Some Postman users resorted to Newman, while others wanted a more integrated workflow for choosing files and defining uploads programmatically. The signals are mostly from 2018–2020, so verify whether these gaps still exist before building.
For API testers and developers. Mentioned from Sep 2018 to Apr 2026 on GitHub and Hacker News.

For those of us working alone (like students) there's literally no reason for this to not work. Instead, we're in a position where no one can use it because it won't work for shared runners
Currently, it isn't possible to programmatically upload files using Postman. There is a workaround but the inability to leverage the Postman UI when editing the file location isn't ideal – File uploads using Newman
