How do I pass credentials to a LiveCycle REST endpoint?

[Jared_Langdon]

I would like to use a LiveCycle REST endpoint for an application-to-application integration point.  The documentation says:

"When you invoke a service using REST, you are prompted for a LiveCycle user name and password. However, if you do not want to specify a user name and password, you can disable service security."

I don't want to disable security, nor do I want to require a user to interactively enter a password.  Any guidance on how to get this done is appreciated.

A clarification.  I wish to invoke a LiveCycle REST endpoint by passing the user credentials with the request.  Perhaps in the HTTP header or as get or post parameters.  Is this possible?  Any help is appreciated.  Thanks.
