Send user and password as parameter in Jira Implementation

Send user and password as parameter in Jira Implementation

Hi, I will make a Jira integration for the service desk plus. The file Jira.xml need a user/pass for connect to the Jira over the rest api and my intention is not use and service user in jira and use the Service Desk Plus User/Pass to connect
Exists some parameter like $USER $PASSWORD that pass this parameter to the jira rest api?
