HTTP Receiver empty payload URL only

Hi All,

I need to create a URL to call out to Oanda to get exchange rates and the response returns the required data in XML.

Based on the query builder the vendor supplies on the line the URL would be similar to: https://www.oanda.com/rates/api/v1/rates/AUD.xml?xxxxxxx&decimal_places=5&date=2014-09-16&fields=averages&quote=NZD

The parameters would be built from values passed via XML payload from ECC; I found this discussion that looks like it will help me here.

Is it possible to use the HTTP receiver adapter to send a URL with no body?

If so could someone kindly point me in the right direction as to how to do this and if not what approach should I take?

Thanks in Advance

Julian
