Can I get the accountId from the API, when I only know the email or Display name

[Luka Simon Thies]

Hey there.

I want to automate some tasks and I need to update a pate and tag certain users.

I can mention them with their accountId, as far, as I understand, but I need to somehow get these only from their Display name or email address.

Is there a solution for this?

Hi @Luka Simon Thies Welcome to the community!

You may try below:

When I try that, I get an 400 error

Please try- https://yoursite.atlassian.net/rest/api/3/user/search?query=youremail

Thank you, this works for the email.
Would this also work when I only have a Display name for example?

I tried it with "firstname%20lastname" and with "firstname+lastname", but that returns all users that have either of those in their name.

Unfortunately, this behavior makes it difficult to retrieve a specific user if multiple users share parts of the name. There isn't a built-in way to force an exact match using this endpoint.

Okay, then I'll have to get around that somehow.

But thank you for your help.
