New user id format

[Adrien Merat]

Hello,

I've noticed that since a month or two now, when we create new users, the format of their id has changed compared to older accounts. Indeed, before it was a 24 alphanumeric characters string, but now it seems to be a 6 digits number followed by ":" and a uuid containing some dashes.

With this new format, does the user_id is still the whole text after the /people/ in the URL or does it starts after the ":" ?

Does it still work to send a comment via API with `[~accountid:<user_id>]` to ping a user ?

The documentation is quite late on these topics and doesn't mention the new id formats. Would be nice to keep it updated :)

Thank you.

I found this topic https://community.developer.atlassian.com/t/account-id-formats/41061 but it doesn't explain why Jira suddenly changed the format for us only now and not earlier since this topic is from 2020. What's the Jira internal logic to choose user_id formating ?
