We have teams with several projects and creating it through templates is not practically scalable, hence require an API to create JIRA integration manually
We have a base template for all of our JIRA epics. We are not able to link that to the Aha epic unless we do a copy and paste. Incredibly inefficient. We need to automate pulling over the Idea description to the base customer template before promoting over to JIRA.
We also need this for our Open Source projects integration - the number of workspaces that you have to manually update are too many for the direct interface approach. An external API is going to be essential in the era of DevOps.
If not the ability to completely configure the JIRA integration from the API, another good state would be the ability to attach the template via API to a product.
