Below the list of configured Application Links is a form to add a new Link. Fill in the details of the connection as in the example below (with your Salesforce instance name) and click Add.
You will now see your new Application Link in the list of configured Application Links, however under the Authentication column it will say Not Configured.
Authentication now needs to be configured so that JIRA can communicate with Salesforce.com. In the Actions column of the new link, click Configure Authentication and enter the Salesforce.com username and password.
Click Update. The link will now show Configured in the Authentication column.
The default Application Links interface has been replicated as part of the connector as the default interface was not accessible to all JIRA administrators.
Application Links can still be added through the default interface but this documentation will focus on the connector interface.
