How to configure sender REST adapter with multiple GET parameters

Hi Everyone,

i have configured the REST adapter with below endpoint and I am expecting 3 variable being passed via HTTP GET.

See attached configuration

General Tab

Endpoint

REST resource

I am doing a call using the below URL

http://host:port/RESTAdapter/salesforce/DPVR?raw_id=100151104604W400☆t=20150101&end=20160101

The sender Adapter is getting selected but the Dynamic configuration does not show the custom attributes which i have configured in the channel

As i cannot find the custom attributes i am not able to read them in my mapping .

Please let me know if anyone has configured multiple GET parameters in Sender REST adapter and used them in mapping.

Thanks

Husain
