  • Not able to invoke the Resful API from Biztalk

    • I was tring to built a simlar stuff for another restful API.
      I have built an API based on the sample API shown here. .
      after hosting the API i tried browsing as 
      http://localhost/WebApiPOC/api/products/1 and it returns valid result.Now i want to call this from biztalk .I created  an schema as simlar to shown as HttpRequest and built an orchestration to invoke the restful sevcice.I configured the end uri for reqresp port as http://localhost/WebApiPOC and did the other settings as well along with selecting the endpoint behaviour as biztalkWebHttp. i am placing the below message at the folder location .
      <ns0:BiztalkWebHttpRequest method="GET" uriTemplate="/api/products/{id}" xmlns:ns0="http://InvokeWebApiPOC.WebApiRequest">
        <param name="id">1</param>
        <header name="Content-Type">application/xml; charset=utf-8</header>
      But I end up in getting the argument exception while sending the http request to the API. See below error msg. 
      "A message sent to adapter "WCF-Custom" on send port "SndRcvPort_SndRcvWebApiREqRespMsg" with URI "http://localhost/WebApiPOC" is suspended. 
       Error details: System.ArgumentNullException: Value cannot be null.
      Although i am trying to append the URI in the message inspector class but that is not reflecting in the error.
      I suspect the endpoint behaviour is not working for me.Is there any way to debug the endpoing behaviour. I tried writing into eventlog from Message inspector class in the BeforeSendRequest method  but that also not appearing in the event log.   
      I have added the message inspector d.. in the gac.
      Any idea if i am missing something ????
  • Using XML as a Parm

    • I am using, and loving, the sample you created but I am having an issue. I need to call a service that uses XML as a parameter in the query string example: 
      I am sending the following message:
      <?xml version="1.0" encoding="utf-8"?>
        <param name="FXMLRequest"><convert><client_id>myclientid</client_id><expr></expr><exch>USD</exch></convert></<param>
        <header name="Content-Type">application/xml; charset=utf-8</header>  
      I end up with:
      It appears that the behavior ignores all xml tags in the message as characters in the parameter and reads only the values contained in the tags. Do I need to build the xml string in side the behavior?
