calling external script upon successful payment processing

[upuaut]

Hi All,

 

I seriously need some help figuring this out. please help.

 

Scenario:

 

Once a customer buys a particular product and pays for it successfully (via authnet or paypal), I need to perform additional processing and issue special instructions to them. I need some help

 

My questions

1- where in the code should I insert such trigger? It is important to trigger ONLY upon successful payment authorization.

2- I don't know much PHP. is it possible to make system calls or execute other scripts using PHP? My need is to execute a perl script (lang I can prog in) directly on the same server, or make a web call to the same server.

 

3- the trigger would take place for only a subset of items.

 

4- I'd need to pass the order ID to the external script. How can I acheive that?

 

The trigger will be silent and should/would not affect process flow of osc. Basically, make the call and don't wait for a response.

 

your help is greatly appreciated.
