问题 So obviously the paypal API code is not very easy to read or understand, neither is the documentation which is provided. This guy agrees with me. If you’ve spent more than a few minutes in the PayPal documentation, you will know it’s easier to manually decrypt a 1024 bit RSA private key than to understand the PayPal Digital Goods with Express Checkout API. So I finally figured out how to get PHP to communicate with the paypal API through this sample code: https://ppmts.custhelp.com/app

问题 I have a site in development that I cannot get the shipping to transfer with using Google Checkout or Paypal Express. I believe the error with Google Checkout is the fact it needs an HTTPS callback url and since I am just developing currently I do not have one. As for the Paypal Express setup, I have followed every possible help guide out there and I seem to be hitting a road block. Why is shipping not showing up on the paypal site? Here is a link to the development site. http://38.98.53.62/

问题 I am using the .NET SDK for Paypal Payments Pro. The sample application stores the API account credentials in the website's Web.config file. I'd like to be able to pull these credentials from the database, instead. Some searching turned up this entry, which asks the same question: Edit Settings in web.config. Unfortunately, the accepted answer didn't address how to store the credentials elsewhere; instead, it showed how to programmatically modify the Web.config file. Is there any way to

问题 Your images have probably been run through Apple's "pngcrush" program and therefore are not valid PNG files any more. I'm told that Apple's "pngcrush" has a way of reverting the damage and recreating a valid PNG from the crushed file, perhaps with some loss of data. If you can look at the beginning of the file and the bytes "CgBI" appear starting at byte 12 instead of "IHDR", that will confirm that the file has indeed been apple-pngcrushed. 回答1: Ah! @vivek, instead of this line: [self

问题 Payflow supports a Silent Post URL, which is a page that will be notified upon completion of a successful transaction (payment, refund, etc...). The Silent Post URL can be configured via the PayPal manager. Most similar payment systems implement the notion of a "post back" where the receiving software can post back the results to make sure that the transaction information is legitimate and not originating from a hacker. Payflow doesn't appear to support a post back and the Payflow Pro

问题 I have a scenario , where if the server is down , we need to do the "Refund" of currently made transaction entirely through the application . Is it possible ? The following paypal Refund API requires Access token of oAuth from the merchant account , but i dont see any example if oAuth from merchant is possible on mobile end ? the sdk examples are doing this at server end mostly. PaypalRefund "PaypalHere SDK" allows this , but that API is different from regular Paypal API. PaypalHereApi 回答1:
