IPN required

[Shades]

Hello, so I just need a simple IPN for me to credit an item. If anyone has an example or would be able to help would be amazing!

So with my donator page people would be able to purchase the item however there is different options for different quantity’s however it’s the same item if that makes sense

What payment processor are you needing integration with? Once you figure that out, look at their documentation.

IPN is the standard name for Paypal (Instant Payment Notification), if not mistaken, and they do supply a simple IPN sample.

Could be Stripe, or any payment merchant ( or whatever they're known as ) - IPN isn't specific to PayPal.

On the same note: Stripe IPN: https://github.com/denis-dima/stripe-ipn

?

(nb: No idea on the code quality/working, just first thing on Google... )

For mccodes? 

My developer made me an IPN for mccodes if that interests you.

So below is my donator page. I need it for Paypal. Finding it difficult to understand the IPN. Can anyone help?

IPN is very simple - Paypal can make life rather tricky however as the documentation often varies from the actual code and in fact the sandbox api has been known to differ from the production api making testing potentially expensive.

There's certainly a couple of peeps here how could implement this for you in double-quick time; and/or point you in the right direction.

You state that you are finding to difficult to understand .. exactly what aspect? https://developer.paypal.com/docs/classic/ipn/ht-ipn/ Makes things reasonably clear though it may not be the architecture you require.

Still doesn't work? What am I doing wrong. Can someone please help.

did the community die?

Are you facing any errors? Is your PayPal set up correctly?
