HTTP Call

Connector Type HTTP Call is used to call HTTP endpoints leveraging HTTP Client Module 1.0 standard. It follows the principle of passing HTTP call input in a XML representation package into common Connector envelope:

XML

<HTTPCall>
  <csrf enabled="true" token-endpoint="/sap/opu/odata/sap/API_SALES_ORDER_SRV/" token-method="GET"/>
  <http:request xmlns:http="http://expath.org/ns/http-client" method="POST" href="/sap/opu/odata/sap/API_SALES_ORDER_SRV/A_SalesOrder">
    <http:header name="content-type" value="application/json"/>
    <http:header name="accept" value="application/json"/>
    <http:body media-type="application/json" method="text">eyJTYWxlc09yZGVyVHlwZSI6Ik9SIiwiU2FsZXNPcmdhbml6YXRpb24iOiIxNzEwIiwiRGlzdHJp
YnV0aW9uQ2hhbm5lbCI6IjEwIiwiT3JnYW5pemF0aW9uRGl2aXNpb24iOiIwMCIsIlNvbGRUb1Bh
cnR5IjoiMTcxMDAwMDIiLCJQdXJjaGFzZU9yZGVyQnlDdXN0b21lciI6IkNyZWF0ZWQgdmlhIE9E

LUZHLVIzMDAiLCJSZXF1ZXN0ZWRRdWFudGl0eSI6IjIifV19</http:body>
  </http:request>
  <auth type="OAUTH2" rfcdest="CUSTOM_DEST">
    <http:request><!-- custom request goes here --></http:request>
  </auth>
</HTTPCall>

Key values to be passed in the call:

csrf - used when CSRF protection is on on the endpoint - requires passing token-endpoint and token-method
http:request - specifies method and endpoint to be called
http:header - specifies HTTP headers to be passed to the call
http:body - BASE64 encoded HTTP body
auth - used to call Token Endpoint as part of OAuth authorization

Results of HTTP Call Connector execution are return in format as below:

XML

<HTTPCall xmlns:asx="http://www.sap.com/abapxml" xmlns:http="http://expath.org/ns/http-client">
	<http:response message="OK" status="200">
		<http:header name="~response_line" value="HTTP/1.0 200 OK"/>
		<http:header name="~server_protocol" value="HTTP/1.0"/>
		<http:header name="~status_code" value="200"/>
		<http:header name="~status_reason" value="OK"/>
		<http:header name="content-type" value="application/json; charset=utf-8"/>
		<http:header name="content-length" value="1022"/>
		<http:header name="dataserviceversion" value="2.0"/>
		<http:header name="sap-perf-fesrec" value="4075898.000000"/>
		<http:body media-type="application/json; charset=utf-8" method="">eyJkIjp7Il9fbWV0YWRhdGEiO</http:body>
	</http:response>
</HTTPCall>

Authentication:

basic - based on SM59 RFC destination
OAuth Client credentials - based on Token destination Int4 Suite Configuration

Authentication request can be customized in <HTTPCall>
