Hi all, I am using the express checkout feature of paypal for parallel payment.I am trying to make parallel payment to multiple different sellers in shopping cart using a credit card so that a buyer who has no paypal account can checkout using credit card. https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_api_ECParallelPaymens I have run into one unique problem. The respose from paypal server is success if the request is following request. Request: -------- METHOD=SetExpressCheckout &USER=API_USERNAME &PWD=API_PASSWORD &SIGNATURE=API_SIGNATURE &VERSION=84.0 &AMT=10.00 &RETURNURL=http://localhost:7725/Shopping/Index &CANCELURL=http://localhost:7725/Shopping/PaymentScreen &SOLUTIONTYPE=Sole &LANDINGPAGE=Billing Response: --------- TOKEN=SUCCESS_TOKEN &CORRELATIONID=ef25abb98495a &ACK=Success &VERSION=84%2e0 &BUILD=3622349 Whereas if i update the above request to make a payment to multiple sellers as below i get the error.The request i am making for parallel payment adheres to that given in the documentation.I am not sure why i am getting the error.
