GitLab

Temp Url
https://gitlab.com/uploads/tmp/1518381932-32940-0001-7618/1.svg

Img Url
https://gitlab.com/uploads/-/system/group/avatar/1066797/first.png
https://gitlab.com/uploads/-/system/group/avatar/1066797/second.png

URL Pattern
https://gitlab.com/uploads/-/system/group/avatar/{userid}/filename.ext

Notes
Request Pattern: Single request on final submit -> file + other data in multipart, not json
History Pattern: old image not retained, but the "filename.ext" seems to be any dummy name

On button click, two APIs are sequentially executed. One for media upload, other for other data updates.
