Hayim, We use the Expath http-client a lot. Based on the small amount of code that you have pasted below, I can share some code snippets that we might use to do something similar. The below code has been pulled from various files and has not been tested but my hope is that it is close enough to help you identify how to use the http-client library to get the results you are looking for. import module namespace http = "http://expath.org/ns/http-client"; import module namespace jx = "http://joewiz.org/ns/xquery/json-xml" at "../../../core/json-xml/modules/json-xml.xqm"; let $constructed-url := "http://52.12.26.11:8080/collatex/collate" let $headers := <http:header name="Content-Type" value="application/json"/> (: NOTE: headers should be formatted the following way (they do not use a parent tag) <http:header>...</http:header> <http:header>...</http:header> :) let $get-request := <http:request href="{$constructed-url}" method="GET"> <http:header name="Connection" value= "close"/> {$headers} </http:request> let $response := http:send-request($get-request) let $response-body-decoded := util:base64-decode($response[2]) let $parse-response-body := jx:json-to-xml(xs:string($response-body-decoded)) return $parse-response-body Does this help? If you have more questions, let me know. I am happy to help.
