How to get Jira issue id from issue key

[Sarangadhar.Sahani]

Zephyr apis accept issueId. How to we programmatically get the corresponding issueId for an issueKey?

If we have to use combination of Jira and Zephyr apis, then how do we authenticate programmatically for Jira api calls like we do for Zephyr through JWT.

What platform are you on?

1. Jira server
   • You can call <JIRA_BASE_URL>/rest/api/2/issue/{issueIdOrKey}
     • This api accept issue id or key as path parameter.
   • For authentication on server platform you have two options
     1. BasicAuth (base64 encoded username and password)
     2. oAuth
   • You can read more about it here https://docs.atlassian.com/software/jira/docs/api/REST/8.3.2/
2. Jira Cloud
   • You can call <SITE_URL>/rest/api/3/issue/{idOrKey}
     • similar to server this api also accept issue id or key as path parameter
   • For authentication on cloud platform you have two options
     • BasicAuth with API Key (base64 encoded email and api key)
     • oAuth 2.0
   • You can read more about this here https://developer.atlassian.com/cloud/jira/platform/rest/v3/

I am getting 404 if I try GET/rest/api/2/issue/{issueIdOrKey} even though the issue exists for that key. Any help?

HI @DPKJ There is no issue.id for Jira Cloud as Smart Value

https://support.atlassian.com/cloud-automation/docs/jira-smart-values-issues/

Although, following this doc https://confluence.atlassian.com/automation/find-the-smart-value-for-a-field-993924665.html, you can use the dot notation for whichever issue field ....

So now we can access Xray GraphQL API

I retrieved some email like API 2 and 3 are being made obsolete... I wonder, is this still going to be functional? I would say it is different endpoint to Tempo, but I am not sure...

Hi @Sarangadhar.Sahani ,

You can get it using REST API 

 /rest/api/2/issue/{issueIdOrKey}

https://community.atlassian.com/t5/Jira-questions/How-I-get-issue-id-of-particular-issue-in-Jira-Service-Desk/qaq-p/977378

If you want to get using JAVA API . You can user IssueMangaer class. From this you can get issue object using issuekey.
