Is it possible to Develop a payment gateway
If you want to directly integrate with banks, you want to become a payment processor. This is quite hard to achieve (especially on the compliance side) and the market is dominated by a few giants (First Data Corp., Total System Services Inc. (TSYS), Vantiv Inc., Global Payments Inc. and Heartland Payment Systems Inc.). A payment gateway however is a system that accepts card payments, and offers v

Paypal Express Checkout provide full items discount
As far as I know the "ITEMAMT" should not be zero . It must be greater than zero . So , if you use like this, it should work : &NOSHIPPING=0 &PAYMENTREQUEST_0_SHIPPINGAMT=2.00 &PAYMENTREQUEST_0_SHIPDISCAMT=0.00 &L_PAYMENTREQUEST_0_NAME0=Item1 &L_PAYMENTREQUEST_0_QTY0=1 &L_PAYMENTREQUEST_0_AMT0=25.91 &L_PAYMENTREQUEST_0_NAME1=Discount &L_PAYMENTREQUEST_0_QTY1

Sandbox Error: Total
The error you're getting is very straight forward. The API request sent to PayPal must have an empty value for the AMT parameter, or the AMT parameter is getting left out of the request entirely. You need to have your developer save logs (he should be already) so that you can see the raw API request and response getting generated. What you've shown here is basically the response, so you just ne

Bug with negative amounts in PayPal API
Interesting. Normal payments don't have that restriction (I pass a negative amount item just like what you describe on a frequent basis). What they're telling you to do is take the discount off another item. So your example cart with that discount would be Item 1 - £10 Item 2 - £20 Item 3 - £40 <-- Removed £10 discount Item 4 - £10 Delivery - £5 Total - £85 <-- total refle

Can I use a chained payment in combination with 3-day capture?
Sounds like you'd need to use a Preapproval profile for the first part, and then you could hit the Pay API within that 3 days and process the chained payment using the Preapproval key. That would send the funds to the primary receiver, and then you'd use ExecutePayment to trigger the secondary payments when you're ready to process them.

update from SSL 3.0 to TLS Paypal
The issue is related to the POODLE Attack Vulnerability that is causing SSLv3 versions to bleed sensitive information. This was discovered in September 2014, and has affected almost all technological companies. For this reason, PayPal has disabled SSLv3 encryption, and have led everyone to upgrade their system to use a newer version of TLSv1 encryption. I cannot answer the need for a major tech

PayPal API - discount?
I'm curious where you see that there's a "discount" parameter even available in these calls..?? It's not listed in the API reference for Pay or SetPaymentOptions. What you'll need to do is add the discount as a line item in SetPaymentOptions with a negative amount. So it would be an extra line item with -0.15 as the value. You could name the item "discount" or whatever you want, but again, the

How to automate a donation receipt system
Yes. You would use Instant Payment Notification (IPN) for that. Basically, you create a script that sits on your web server and "listens" for data. Any time a transaction hits your PayPal account their server will POST all of the data about that transaction to your listener script. Your script receives the data, and within it you can process the data however you need to. You can generate cust

The form you have in your post is using what is called "Advanced Integration". However, what is usually recommended for most sellers/merchants is "Standard Integration".

Paypal Chained Payments - "The login information you entered belongs to the recipient of this transaction."
Update: I did move to the Live environment last week and found out that no, there's no way to send money from an account that is also one of the receivers. Different email addresses don't enable this either. While there's no reason I can think of that a user would want to do this when they're the sole receiver, there are reasons that you'd want to make a purchase through a system even if you are

Troubles with Paypal Adaptive Payments API
I think you're getting lost in the fact that Adaptive Payments transactions actually have separate IPN's for the app and for the receiver. In cases where you're acting as both, you would get 2 separate IPN's. What you've included here is the receiver/transaction specific IPN. That would not include a PayKey, but instead, a transaction ID, like you're getting. You'll notice there is no PayKey

It's using NVP instead of SOAP, but you can see that it's including

Paypal Payflow Pro API is returning null in AVSADDR and AVSZIP for card declined transactions
The transaction id "A1X07C06757F" is not a decline . It indicates that card number you entered is incorrect . Since the card number itself is incorrect , PayPal will not send the information to the processor and therefore there is no response related to the AVS and CSC . If a transaction is declined(result=12)or successful then you will see the AVS and CSC response .

How do I allow the user to pay via PayPal's REST API, but without them having to register a PayPal account?

What to use as a unique ID for an order/transaction?
So I realized the Invoice ID is indeed accessible to the buyer through their confirmation email and transaction details page.
