Webshop with API call after successful payment [closed]

I am developing Custom Studies for Sierra Chart’s ACSIL framework. Let’s call them programs from now on and I want to redistribute them. See the working of that here: https://www.sierrachart.com/index.php?page=doc/AdvancedCustomStudyInterfaceAndLanguage.php#Redistributing.

I want to create a webshop where I can sell these Studies. The client side is simple, it should list the available programs. The payment will be done with Stripe. After a payment is successful, I want to make an API call to the Sierra Chart WebAPI, to redistribute the programs automatically.
The Sierra Chart WebAPI is located here: https://www.sierrachart.com/index.php?page=doc/WebAPI.php.

I am new to web development, what technologies should I use?
I would be the happiest, if there is an already existing solution out there, where I can automate what should happen after a successful payment, is there any?
