The requirement is for a Paypal IPN listener (PHP) that can be installed on one of our Linux servers. This could be a standalone php package or a class that can be called into one of our own packages.
There will be many different Paypal customers using the listener as they are all clients of our SaaS application running their own websites on different URLs. It would be up to them to configure their own Paypal accounts to use IPN and point at this listener.
On a successful event, the listener will post to another URL (to be configurable) with all the Paypal variables received. The initial URL will be supplied by us.
Please ignore the budget figure of £100 - we would like all offers please.
