Problems with Betfair API web service

[billborric]

I am trying to connect to the Betfair web service API with the following code...

LOCAL loBFGlobalService AS "XML Web Service"
* LOCAL loBFGlobalService AS "MSSOAP.SoapClient30"
* Do not remove or alter following line. It is used to support IntelliSense for your XML Web service.
*__VFPWSDef__: loBFGlobalService = [URL unfurl="true"]https://api.betfair.com/global/v3/BFGlobalService.wsdl[/URL] , BFGlobalService , BFGlobalService
LOCAL loException, lcErrorMsg, loWSHandler
TRY
    loWSHandler = NEWOBJECT("WSHandler",IIF(VERSION(2)=0,"",HOME()+"FFC\")+"_ws3client.vcx")
    loBFGlobalService = loWSHandler.SetupClient("[URL unfurl="true"]https://api.betfair.com/global/v3/BFGlobalService.wsdl",[/URL] "BFGlobalService", "BFGlobalService")
    * Call your XML Web service here.  ex: leResult = loBFGlobalService.SomeMethod()
    *login(request AS LoginReq) AS LoginResp

CATCH TO loException
    lcErrorMsg="Error: "+TRANSFORM(loException.Errorno)+" - "+loException.Message
    DO CASE
    CASE VARTYPE(loBFGlobalService)#"O"
        * Handle SOAP error connecting to web service
    CASE !EMPTY(loBFGlobalService.FaultCode)
        * Handle SOAP error calling method
        lcErrorMsg=lcErrorMsg+CHR(13)+loBFGlobalService.Detail
    OTHERWISE
        * Handle other error
    ENDCASE
    * Use for debugging purposes
    MESSAGEBOX(lcErrorMsg)
FINALLY
ENDTRY

SET TEXTMERGE ON

TRY
        *loBFGlobalService .ConnectorProperty("Timeout") = 240000
        lcXML = loBFGlobalService.login(lcLogin)
        xmltocursor(lcXML)
        BROWSE
CATCH TO loException
    lcErrorMsg="Error: "+TRANSFORM(loException.Errorno)+" - "+loException.Message
    DO CASE

    OTHERWISE
        * Handle other error
    ENDCASE
    * Use for debugging purposes
    MESSAGEBOX(lcErrorMsg)
FINALLY
ENDTRY

...however the "lcXML = loBFGlobalService.login(lcLogin)" returns the following object...
error -

Client:Incorrect number of parameters supplied for SOAP request HRESULT=0x80070057: The parameter is incorrect.

The above XML was generated by a utility available on the Betfair site, but they also have some downloadable XML files which are slightly different...

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="[URL unfurl="true"]http://schemas.xmlsoap.org/soap/envelope/"[/URL] xmlns:xsi="[URL unfurl="true"]http://www.w3.org/2001/XMLSchema-instance"[/URL] xmlns:xsd="[URL unfurl="true"]http://www.w3.org/2001/XMLSchema">[/URL]
  <soap:Body>
    <login xmlns="[URL unfurl="true"]http://www.betfair.com/publicapi/v3/BFGlobalService/">[/URL]
      <request>
          <ipAddress xmlns=""></ipAddress>
        <locationId xmlns="">0</locationId>
        <password xmlns="">bfpassword</password>
        <productId xmlns="">82</productId>
        <username xmlns="">bfusername</username>
        <vendorSoftwareId xmlns="">0</vendorSoftwareId>
      </request>
    </login>
  </soap:Body>
</soap:Envelope>

...both forms generate the sane error.

Hoping someone can shed some light on this.

when i use this form of soap call you are creating an object in your case called loBFGlobalService.
with this object I do not build and pass the soap envelope and just set the properties and call the method

loBFGlobalService.locationId=0
loBFGlobalService.productId=82
loBFGlobalService.username="myUserName"
loBFGlobalService.password="myPassword"
lResult=loBFGlobalService.login()

another possiable iteration not knowing or looking at the wsdl would be

lResult=loBFGlobalService.login(lnLocationId,lnProductId,lcUser,lcPassword)

I am also assuming that LocationId and ProductId are numeric. This information can be found in the wsdl located at

https://api.betfair.com/global/v3/BFGlobalService.wsdl

I looked at the wsdl and indeed the ProductId and LocationId are looking for INT. Good Luck
