How to assign an issue to a Jira user based on an email address from an external system

[Yong Yang]

Hi,

I need to integrate Jira Cloud with an external system and then assign an issue to a user based on an email address. Steps are:

1.Use Jira automation to call a webhook to read a user's email address from an external system.

2.Assign the issue to Jira user with this address.

I don't know how to implement the step 2. May I know if anyone has any experience? 

Thanks,

YY哥

Hi @Yong Yang 

Assuming the email is identical to the one in Atlassian you can call the API to get the UserID by email. Once you got the ID you have the Account and can use that to assign it.

The Jira Cloud platform REST API (atlassian.com)

There's a great tutorial on how to use the API to lookup an account ID from an email address here:
