Is there anyway to make a license code reply upon every payment done by customer?

we are online software dealer and we need to send codes(likely license code) to our customer upon every payment by facebook automatically. i there any function to do that? please advice, much appreciated.

At the moment we do not have a function that can post data direct, you can however request the user to provide their facebook email and then use the autoresponder to post this data to their wall.

To provide more flexibility with sending the license code, I would recommend using a custom thank you page and send the POST data to a php page where you can manipulate it with a greater degree of control http://www.jotform.com/help/213-Send-POST-Data-From-JotForm-Using-PHP-in-Custom-Thank-You-Page

You can also check out our web hooks integration for real-time notifications that you can use to integrate with the sending of the codes http://www.jotform.com/blog/85-Send-Instant-Submissions-with-Webhooks
