I'm not sure if this is the kind of integration you're looking for, but I created an add-on that allows to show Sharepoint data on JIRA issues. Take a look at Sharepoint Select Custom Field on the Marketplace.
Not sure if you're still searching for this, but I though it could help the people that might come into this post with the same question.
With the right set up, you can integrate Jira into MSFT Teams (built around SharePoint) and see / edit Jira tickets in Teams (doesn't seem to be the case if you want to operate from the Jira interface - which I need so we can ditch Confluence completely since the majority of our org doesn't use it). hmm.
This add-on is no longer available - it has been archived.
I am trying to find the same information. Is there anyone who knows how to integrate JIRA/Confluence/SharePoint? I installed the SharePoint Connector for Confluence, but receive error message: :This add-on couldn't be loaded. It has one or more errors that prevent it from being enabled." There is no additional information provided.
The SharePoint Connector for Confluence is only able to integrate content from SharePoint to Confluence or the other way around. It is not supposed to work with Jira. If you want to install the app in Confluence and SharePoint you may follow this guide.
When you encounter problems with the installation of this app please contact our support team.
