You need an API token to integrate with Jira on Atlassian cloud. To create the API token:
Sign in to Atlassian using an account with write access to Jira projects.
The link opens the API tokens page. Alternatively, to go to this page from your Atlassian profile, select Account Settings > Security > Create and manage API tokens.
- Select Create API token.
- In the dialog, enter a label for your token and select Create.
- To copy the API token, select Copy, then paste the token somewhere safe.
You need the newly created token, and the email address you used when you created it, when you configure GitLab.
