How to add username and pwd in sender REST adapter?

Hi Expert,

I have developed Rest to proxy scenario. I created the Url as http://<server>:<port>/RESTAdapter/<pathspecifiedinthecommunicationchannel>. Client  conveyed they  don’t support either user authentication as well as certificates while trying to push data to us,As they don’t have the option of configuring WS user and requesting to disable the basic authentication on our end.

Is this possible in sender REST channel to add user and password also in above url?

Any body can please help me for above issue?

Thanks,
