Create a webservice for confluence to authenticate api requests from team city, octopus etc Edited

[Andy Stavrinou]

So the end goal is to have a confluence page that contains information from external tools, such as team city, octopus  etc. 

I thought i could do this via an ajax request in a html markup module. but this is not secure and not very useful. 

ideally i would like to create a backend service for confluence, that would call the relevant api, and then call our azure keyvault api to provide the octa sign in authentication.  so we could just make a get request from the mark up module on the page, with authentication already having being done once the user has logged in to confluence. 

Is this possible to add a backend script to confluence? is there anything that already does this?
