I am having problems consuming a WCF web service (PaySimple's v3.00 API) using php curl. I am trying to post an xml payload to the service and I keep getting a 400 - Bad Request error. When I using Firefox's Poster add-on, I can post the very same payload and I get the expected response - 200 OK with an XML response containing the required response. Here's a snippet of my code:\[code\] $ch = curl_init(); $payload = $createPayload(); $length = strlen($payload); $headers = array("Expect:"); if($isPost) { curl_setopt($ch, CURLOPT_POST, TRUE); curl_setopt($ch, CURLOPT_POSTFIELDS, $payload); $headers[] = "Content-length: $length"; } else { curl_setopt($ch, CURLOPT_HTTPGET, TRUE); } if($requestType == 'xml') { $headers[] = 'Content-Type: text/xml; charset: utf-8'; $headers[] = 'Accept: application/xml'; } else { $headers[] = 'Content-Type: application/json; charset: utf-8'; $headers[] = 'Accept: application/json'; } $headers[] = "Connection: close"; curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0); curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0); //debugging curl_setopt($ch, CURLOPT_VERBOSE, TRUE); $fh = fopen('curl_debug.txt', 'w'); curl_setopt($ch, CURLOPT_STDERR, $fh); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); $response = curl_exec($ch); curl_close($ch);\[/code\]$payload contains the following value:\[code\]<AddCustomer xmlns="http://api.paysimple.com"><userkey>APIUser1989</userkey><apikey>pxTbp4F6y7JuaMu36qazEw51JiqUA7lGme0j62r3UeQyNojvEfpNo7tn4pLq0yEULHz5KykHWV6AjNQJEyskCw0tXSKZ0vcP5mCynh1IgfQEH4NdXRkXeMNAGEdx6Ee0</apikey><customer xmlns="http://api.paysimple.com" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><ApiConsumerData/><PsReferenceId>0</PsReferenceId><AltEmail>[email protected]</AltEmail><AltPhone/><BillingAddress1>TestBillingAddress1</BillingAddress1><BillingAddress2/><BillingCity>TestBillingCity</BillingCity><BillingCountryCode/><BillingPostalCode>80202</BillingPostalCode><BillingState>6</BillingState><CompanyName>TestCompany</CompanyName><CreatedOn>0001-01-01T00:00:00</CreatedOn><Email>[email protected]</Email><Fax/><FirstName>TestFirstName</FirstName><LastModified>0001-01-01T00:00:00</LastModified><LastName>TestLastName</LastName><MiddleName/><Notes/><Phone>5551234567</Phone><ShippingAddress1/><ShippingAddress2/><ShippingCity/><ShippingCountryCode/><ShippingPostalCode/><ShippingSameAsBilling>true</ShippingSameAsBilling><ShippingState>0</ShippingState><WebSite/></customer></AddCustomer>\[/code\]Here's what shows up in curl_debug.txt:
