  • Hi Noor,

    Refer the thread: https://social.msdn.microsoft.com/Forums/en-US/f7d91dec-1275-412e-a3fe-17885ba1c962/biztalk-wcf-webhttp-post-method-along-with-example?forum=biztalkgeneral

    Are you able to invoke the POST operation outside BizTalk using something like Fiddler?

    If yes, getting it to work in BizTalk is simple. You can refer this sample.

    You will need the schemas for the Post operation. 

    And specify the HTTP verb as POST in the WCF-WebHttp adapter config-


    Regarding the schemas for the POST oepration-

    1) If web API uses JSON payloads-

    If you are using BizTalk 2013 R2, you can use the JSON schema wizard to create the XML schemas from your sample JSON request/response -



    If you are using an earlier version of BizTalk server, you can first generate the XML format for your JSON sample messages using something like this - http://codebeautify.org/jsontoxml. Once you have the sample XML request/response messages, you can easily create schemas using the Generate Schemas Wizard in a BizTalk project in Visual Studio.

    2) If web API uses XML format messages-

    Just use the sample XML request/response messages from Fiddler and you can create the schemas using the Generate Schemas Wizard in a BizTalk project in Visual Studio.

  • The short answer (totally serious), you just do it.

    The WCF-WebHttp Adapter isn't very fussy about a lot of things so if you have Xml in the Body of the outgoing Message, it will POST Xml to the configured Address.

    You best option, just try it.  If you get any errors, we can help with those.

  • Hi ,

    I have tried, i have an xml in the body but it isn't being passed to Post action, thought it is supposed to

    below is the configuration in biztalk

    i have also given below Outbound Http Headers in Messages tab


    when i call it, i'm not getting XML as an object in post method parameter

    the acknkowledgment class looks like below

    and the xml schema looks like below

    <?xml version="1.0" encoding="utf-16"?>
    <xs:schema xmlns="MazikCareService.Core.Models.HL7" xmlns:b="http://schemas.microsoft.com/BizTalk/2003" xmlns:ns1="https://Birch.HL7.Schemas.Api.MessageControl" xmlns:ns0="https://Birch.HL7.Schemas.Api.AcknowledgmentCode" targetNamespace="MazikCareService.Core.Models.HL7" xmlns:xs="http://www.w3.org/2001/XMLSchema">
            <b:namespace prefix="ns0" uri="https://Birch.HL7.Schemas.Api.AcknowledgmentCode" location=".\AcknowledgmentCode.xsd" />
            <b:namespace prefix="ns1" uri="https://Birch.HL7.Schemas.Api.MessageControl" location=".\MessageControl.xsd" />
      <xs:element name="Acknowledgment">
              <b:property name="ns0:Code" xpath="/*[local-name()='Acknowledgment' and namespace-uri()='MazikCareService.Core.Models.HL7']/*[local-name()='Code' and namespace-uri()='']" />
              <b:property name="ns1:MessageControlId" xpath="/*[local-name()='Acknowledgment' and namespace-uri()='MazikCareService.Core.Models.HL7']/*[local-name()='MessageControlId' and namespace-uri()='']" />
            <xs:element name="Code" type="xs:string" />
            <xs:element name="MessageControlId" type="xs:string" />

    i'm kind of stuck here, trying to figure out what's going wrong, i would appreciate if you could do some help and guide me where i'm going wrong

  • Can you describe what is actually happening?  Output, error, different content?

    It really is that simple.

  • the port from which i'm making call to Post action receives an xml whose schema i shared,

    i have checked the xml is received successfully, but isn't being passed as Post parameter,

    i believe the endpoint and url mapping take the received xml in the body of post action automatically, correct me if i'm wrong

  • Unless you actually using it, you don't really need anything in the Mapping section.

    Did you try just POST?  That's about as generic as you can get.

  • ok just Post in URL mapping, then the url should go into the endpoint address ?

  • Your BTSOperation Mapping is missing the Name attribute.. The Name should be the same nae as the orchestration logical operation Name.

    Else just have POST in the HTTP Mapping section and have ur url configured fully.

  • tried this

    but still getting null

  • Hi Noor,

    make sure of following things

    1) Your opertain name in The BTS action mapping xmlblob shoul match the operation name of the logical port in the orchesration.

    2) have you tested the api using soap Ui tool,meaning can you confirm if it is indeed the issue with Biztalk or PAI,

    if the api is returning response to SOAP Ui then we can focus on the Biztalk part.

  • What is that code you're posting? SendAck?

    That's not a BizTalk thing.
