@EkaterinaShutova welcome to the Atlassian developer community and thank you for considering the Marketplace.
At this time, it is not possible for Marketplace to act on any state outside of Atlassian. Hence, there is no way that a Marketplace install or app could know which Yva server sent the request. I work with a number of SaaS vendors and we usually have to build in some App configuration to point to the right server. For example, you might ask your customer for their “organization name” or whatever identifies them in Yva.
I think it would be pure coincidence if our data residency matched Yva but there are some new Connect data residency features that might help.
