This is how I'm processing the PayPal payment:

//Get payment info from PayPal's API
TbPaypal payPal = new TbPaypal();
string payerId = payPal.GetPaymentDetails(paymentToken);

//Create the new custom property (for the PayerID)
WebServices3.CustomProperty1 customProperty = new WebServices3.CustomProperty1();
customProperty.DeveloperId = "bvsoftware";
customProperty.Key = "PayerID";
customProperty.Value = payerId;

//Add the new custom property
if (order.CustomProperties == null)
{
order.CustomProperties = new WebServices3.CustomProperty1[1];
order.CustomProperties[0] = customProperty;
}
else
{
WebServices3.CustomProperty1[] orderCustomProps = new WebServices3.CustomProperty1[order.CustomProperties.Count() + 1];

//Copy existing properties
int propIndex = 0;
for (propIndex = 0; propIndex < order.CustomProperties.Count(); propIndex++)
{
orderCustomProps[propIndex] = order.CustomProperties[propIndex];
}

//Copy new property
orderCustomProps[propIndex] = customProperty;

//Replace order's custom properties
order.CustomProperties = orderCustomProps;
}

ws.Orders_Order_Update(ref token, order); //Update the order to include the payerID

order = ws.Orders_Order_FindByBvin(ref token, orderBvin.ToString()); //Refresh the local copy of the order

//Add the payment
WebServices3.OrderPayment payment = new WebServices3.OrderPayment();
payment.OrderID = order.Bvin;
payment.ThirdPartyOrderId = paymentToken;
payment.PaymentMethodId = "33eeba60-e5b7-4864-9b57-3f8d614f8301";
payment.PaymentMethodName = "Paypal Express";

ws.Orders_Order_AddPayment(ref token, order, payment);

//Process the order
WebServices3.OrderTaskContext orderTask = new WebServices3.OrderTaskContext();
orderTask.Order = order;
orderTask.UserId = order.User.Bvin;

ws.BusinessRules_Workflow_RunByName(ref token, orderTask, "Process New Order");

I looked into the issue that you are having, and the only thing that I can think of is that it may have something to do with the ThirdPartyOrderId. I looked at order # 7502 in the database, and it actually doesn't have any ThirdPartyOrderId set (nor does the corresponding OrderPayment). The ID that should be being set is in the following format: EC- and then a string of 17 letters and numbers. Does that sound like the value you're setting?

I spoke with PayPal's tech support:

The EC- token is only provided when using Express Checkout methods (PAY- tokens are created for all PayPal transactions). There is no way to get an EC- token using the PAY- token.

I'm using their Mobile SDK which only provides the PAY- token. To get an EC- token, the app has to use the Mobile Express Checkout (mobile web page).

Is it possible for BVC to acknowledge the PAY- token? The payment has already been processed at this point by PayPal.

If it's not possible for BVC to use the PAY- token, do you use Mobile Express Checkout? That seems to be the only way to get the EC- token.

You can't process the CVV code through the API because we are not permitted to store the CVV code. As long as the payment gateway permits transactions without a CVV code this should not be an issue.

Mobile Express Checkout is the same as Express Checkout, it just uses pages optimized for mobile browsers. The handshake between the site and PayPal is the same.

Is is possible to initiate the Express Checkout handshake via the BVC web service? I'm referring to the initial call to SetExpressCheckout (providing the order details) that returns the EC token.

From there I will have to open the Express Checkout url (using the EC token) in the app for the user and catch the PayPal redirect request to determine whether the payment was made or canceled.

Running a workflow through the web service only returns a bool. How would I get the result/token? Is it stored in the order?

I ran BusinessRules_Workflow_RunByName(ref token, orderTC, "Third Party Checkout Selected") and refreshed the local order but the ThirdPartyOrderId is empty ("").

I attempted this with the same order multiple times.

Yes, it returns true. Ryan checked the notes and they're empty too.

I also tried running the workflow by bvin (09739bec-8974-4c38-b026-f6ca8aed615d) and that returned true but failed to update the ThirdPartyOrderId and notes.

Does the workflow rely on anything in the order? The line items, account and addresses have been added and tax has been calculated.

-

I have to catch the redirect to the return URL in the app and close the UIWebView that is displaying the PayPal Express Checkout.

If I end up having to make the request outside of BVC, I'll make sure to provide the invoiceId.

That fixed the token issue. After adding the two custom properties, the EC token is set in the order after calling the workflow. I confirmed the token is valid by testing it with the PayPal checkout URL.

Calling the workflow is throwing an exception (see below). It appears that the workflow may be attempting to return html relating to paypal (you can see links to paypal images). I tried twice and both tries threw the same exception.

Ok, I just wanted to make sure that was expected.

PayPal's documentation shows that you can provide redirect URLs for transaction complete and cancel.

Is the URL that the user is redirected to after completing the PayPal checkout different from the URL used after canceling the payment? I saw that canceling the process sends them back to www.teenyb.com/checkout/checkout.aspx?token=x.

I'm currently catching any redirect to teenyb.com and bringing the user back into the app instead of redirecting to teenyb.com.

From there I will pull the transaction details using the EC-x token and provide BVC with the payeeId.
