Hello, I want to access paypal api with soap. Therefore I want to use gsoap with C++. Are there any alternatives? Because gSoap is not so well documented. The simples approach form e is now, to do simple test requests. This gives „succes“ back: curl https://api-3t.sandbox.paypal.com/nvp \ -s \ --insecure \ -d USER=mi-dick_api1.gmx.de \ -d PWD=XXXXXXXXXXXXXXX \ -d SIGNATURE=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX \ -d METHOD=SetExpressCheckout \ -d VERSION=98 \ -d PAYMENTREQUEST_0_AMT=10 \ -d PAYMENTREQUEST_0_CURRENCYCODE=USD \ -d PAYMENTREQUEST_0_PAYMENTACTION=SALE \ -d cancelUrl=https://example.com/cancel \ -d returnUrl=https://example.com/success TOKEN=EC%2d8PR459601E5516846&TIMESTAMP=2017%2d11%2d11T11%3a44%3a00Z&CORRELATIONID=df58fa2de669&ACK=Success&VERSION=98&BUILD=40680762% When I want to do a request with curl, I use this command, using the request-xml generated from wsdl. "curl --header "Content-Type: text/xml;charset=UTF-8" --header "SOAPAction:ns1:GetBalanceReq" --data ATPayPalAPISoapBinding.GetBalance.req-Dev.xml https://api-3t.sandbox.paypal.com/2.0/" I get this error: Version is not supported I even tried several different Versions (88, 95, 204 as descirbe here: https://github.com/ianfleeton/paypal-express/commit/cebd62f02966f74a8aa3ece5d1793be9327048a0) But no success. Any hints, what I am doing wrong? API-Version: https://developer.paypal.com/webapps/developer/docs/classic/release-notes/merchant/PayPal_Merchant_API_PreviousVersionsNVP/
