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.
