hey @mtreacy002, I am able to create an endpoint POST /mentorship_relation/send_request which successfully establishes the relationship. If this issue is open and if you say, I can try to add other endpoints in the namespace.

@decon-harsh , this issue was already assigned to @khushishikhu and she had submitted a PR (#168) for this. Although, currently there is a block to the issue (#161). As you noticed, we need the POST feature to work first before we can successfully send GET information on mentorship relation. Currently no one is working on issues #161 (I assigned myself but yet to have time to work on it), so, would you like to work on that issue #161 instead?
