We used the open-source FormIO plugin for dynamically generating forms in an application. While using FormIO for file uploads, we faced a limitation; we were unable to send in custom headers as part of the request URL.

There were hacky workarounds to solve this issue in the backend. But, the ability to use custom headers is a common use case. So we requested FormIO to have an optional configuration wherein custom headers could be keyed in as a JSON. We also raised a Pull Request with changes and it was accepted and merged by the FormIO team. Thanks to this, coders can now add custom headers to URL requests in FormIO, using this new optional configuration.
