"Version not supported" in SOAP Request

[ReinerHohn]

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 for me is now, to do simple test requests. This gives „success“ 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/'

(Had to replace the @ after --data) 

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?

The newest version of NVP/SOAP API is  Version 204.

There are certain API Operations that are no longer supported, which can cause a version not supported error message as well.

Here is a listing of API Operations and what versions do not support them:

Here is the documentation on the SOAP SetExpressCheckout API Operation.

Thanks,
