John-Paul thanks for your response but I was just looking to obtain the name of the script (source code) in Prestashop that runs once the order has been processed so that I can then figure out where to place my code do send order data to a mobile app - all I looking to find is the script to modify. Thanks.

Hello tprmedialab,

Unfortunately, there is not just one specific script. Typically one page will use several scripts to function.

You may want to look further into theNotification option in Prestashop.

Also, you may want to post a question in Prestashop's official support forum.

If you have any further questions, feel free to post them below.
Thank you,

-John-Paul
