How to obtain useraccountid for auth purposes

Tom Cartwright

Hello,

We are creating an Atlassian connect app that will use the rest apis to get information about the boards and epics for a given account. We have been able to use the data in the app installation callback to generate a `jwt` token, and then following this guide, create an access token to impersonate a user and obtain the data we want.

But! So far the only way we have been able to obtain the `useraccountid` to generate the `jwt` is by visiting the profile page of a user and copying the value out of the url. How do you programmatically obtain this value for a given user? Do you have to send the user who you wish to impersonate through an oauth process? Or, as an installed connect app, is there a way to find an `useraccountid` for a given user using an api?

Thanks

Follow up to this. From reading through this issue, https://ecosystem.atlassian.net/browse/AC-2442, we were able to get the app installers useraccountid and user_key from the installation callback and signing a jwt with either of these worked - we are able to find other users information on the `/rest/api/3/user/search` endpoint. But this still doesn't feel like a great flow for all users - I was expecting to ask users to perform an oauth-like flow before I would be able to impersonate them on the rest APIs.
