[Request]: Document how to handle file "uploads" from the backend through services #218
Description
Summary
We currently have documentation for uploading files from REST/GQL but not internally within the backend. For example automatically fetching provider avatar/gravatars and uploading / attaching the relation to an entry (user model).
Likewise other hooks/providers that could potentially fetch external images and automatically attach them automatically.
Why is it needed?
Fundamental documentation for internal APIs within the backend stack
Suggested solution(s)
Work with engineering team to explore existing internal APIs for documentation, suggest feature request/enhancements for future development on any lacking or incomplete APIs
