I'm trying to use JIRA API for creating story, task or bug on JIRA tool but account needs to be login first for performing all operations. I have my Azure AD account used for JIRA login on UI but I'm unable to find a way to login using JIRA API. Community, please help here.
Jira's REST API can't use Azure credentials for authentication. Depending on whether you're connecting to Jira Cloud or Jira Server, it uses OAuth, keys and tokens, or usernames and passwords.
