Hello here, I am trying to implement MassPay API on my site with the PHP API but I am having an hard time to make it work. I am using the following script which works perfectly in the Sandbox (I am able to transfer $5 from a Sandbox account to another Sandbox account): ---------------------------------------------------------------------- $apiusername = "mytestaccount_api1.test.com"; $apipw = "[my_test_account_password]"; $certpath = "/securedirectory/cert_key_pem.txt"; $SOAPrequest = <<< End_Of_Quote <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlnssi="http://www.w3.org/1999/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlnssd="http://www.w3.org/1999/XMLSchema" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"> <SOAP-ENV:Header> <RequesterCredentials xmlns="urn:ebay:api:PayPalAPI" SOAP-ENV:mustUnderstand="1"> <Credentials xmlns="urn:ebay:apis:eBLBaseComponents"> <Username>$apiusername</Username> <Password>$apipw</Password> <Subject/> </Credentials> </RequesterCredentials> </SOAP-ENV:Header> <SOAP-ENV:Body> <MassPayReq xmlns="urn:ebay:api:PayPalAPI"> <MassPayRequest xsi:type="ns:MassPayRequestType"> <Version xmlns="urn:ebay:apis:eBLBaseComponents" xsi:type="xsd:string">1.0</Version> <EmailSubject xsi:type="xsd:string">Your payment is here!</EmailSubject> <MassPayItem xsi:type="ns:MassPayRequestItemType"> <ReceiverEmail xsi:type="ns:EmailAddressType">test@test.com</ReceiverEmail> <Amount currencyID="USD" xsl:type="cc:BasicAmountType">5.00</Amount> <Note xsl:type="xsd:string">This is your payment.</Note> </MassPayItem> </MassPayRequest> </MassPayReq> </SOAP-ENV:Body> </SOAP-ENV:Envelope> End_Of_Quote; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL,"https://api.sandbox.paypal.com/2.0/"); curl_setopt($ch, CURLOPT_SSLCERT, $certpath); curl_setopt($ch, CURLOPT_POSTFIELDS, $SOAPrequest); curl_exec ($ch); if (curl_error($ch)) printf("Error %s: %s", curl_errno($ch), curl_error($ch)); curl_close ($ch); ---------------------------------------------------------------------- then I use the same script on my live environment as following: ---------------------------------------------------------------------- $apiusername = "[my_live_API_username]"; $apipw = "[my_live_API_password]"; $certpath = "/securedirectory/cert_key_pem.txt"; $SOAPrequest = <<< End_Of_Quote <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlnssi="http://www.w3.org/1999/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlnssd="http://www.w3.org/1999/XMLSchema" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"> <SOAP-ENV:Header> <RequesterCredentials xmlns="urn:ebay:api:PayPalAPI" SOAP-ENV:mustUnderstand="1"> <Credentials xmlns="urn:ebay:apis:eBLBaseComponents"> <Username>$apiusername</Username> <Password>$apipw</Password> <Subject/> </Credentials> </RequesterCredentials> </SOAP-ENV:Header> <SOAP-ENV:Body> <MassPayReq xmlns="urn:ebay:api:PayPalAPI"> <MassPayRequest xsi:type="ns:MassPayRequestType"> <Version xmlns="urn:ebay:apis:eBLBaseComponents" xsi:type="xsd:string">1.0</Version> <EmailSubject xsi:type="xsd:string">Your payment is here!</EmailSubject> <MassPayItem xsi:type="ns:MassPayRequestItemType"> <ReceiverEmail xsi:type="ns:EmailAddressType">[my_real_personal_PayPal_account_email]</ReceiverEmail> <Amount currencyID="USD" xsl:type="cc:BasicAmountType">5.00</Amount> <Note xsl:type="xsd:string">This is your payment.</Note> </MassPayItem> </MassPayRequest> </MassPayReq> </SOAP-ENV:Body> </SOAP-ENV:Envelope> End_Of_Quote; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL,"https://api-3t.paypal.com/2.0/"); curl_setopt($ch, CURLOPT_SSLCERT, $certpath); curl_setopt($ch, CURLOPT_POSTFIELDS, $SOAPrequest); curl_exec ($ch); if (curl_error($ch)) printf("Error %s: %s", curl_errno($ch), curl_error($ch)); curl_close ($ch); ---------------------------------------------------------------------- and I get an error. Whereas by using the Sandbox fake accounts everything works fine and I get the following result: 2006-06-08T16:40:04ZSuccesseff75340bcb3f1.0000001.0006 with the live version i get the following error: 2006-06-08T16:40:30ZFailurec9d5c76d2a114Security errorSecurity header is not valid10002Error1.0000001.0006 Any idea? Any help is very welcome. Thank you in advance. Sincerely, Fabrizio Virtual Sheet Music - Classical Sheet Music Downloads http://www.virtualsheetmusic.com
