Hi again,
Thanks for this rapid reply.
Unfortunately, I do not control both sides of the exchange - we provide a SaaS to our customers, some of which might use Jira. Therefore, I control the external application, they control their Jira.
In this context what would be the most viable solution? Also, this exchange should happen both ways - e.g. the application I control would need to create entities in the customers Jiras but also their Jiras would be able to create entities in my external app. Would this happen through a webhook? If so, can the webhook be restricted to a certain project (I didnt find such option)
