    - **Username and API Key**: Enter your credentials. For username, use the **full email address** you use to log into Jira.
-   For **API Key**, use a Harness [Text Secret](/docs/platform/secrets/add-use-text-secrets). Go to [Manage API tokens for your Atlassian account](https://support.atlassian.com/atlassian-account/docs/manage-api-tokens-for-your-atlassian-account/) from Atlassian.
+       To obtain your **API Key**: You need to create a scoped API token in Jira with the following scopes:
+     - `read:jira-user` - Allows Harness to read user information
+     - `read:jira-work` - Allows Harness to read Jira issues and related data
+     - `write:jira-work` - Allows Harness to create and update Jira issues
+     
+     To learn how to create a scoped API token, check out [Scoped API Tokens in Confluence Cloud](https://support.atlassian.com/confluence/kb/scoped-api-tokens-in-confluence-cloud/). Once you create the scoped API token, add it as a [Harness Text Secret](/docs/platform/secrets/add-use-text-secrets).

    - **Personal Access Token**: Add your Personal Access Token (PAT) to Harness as an [encrypted text](/docs/platform/secrets/add-use-text-secrets) and select the same in the Jira connector.
