how different payment links on razorpay work in same webhook ?

hi ,
i have started my e learning website and for all the courses , since the price is different , i am keeping different payment links on razorpay .
1. Once the payment is made by my customer for the e learning course ,on my platform- i am thinking of using the pabbly connect to share the link to that course on a mail with a thank you note .
i have followed the process explained in the youtube video and i have a question :
if i have 10 different course , then i need to share 10 different links in the mail body with the different customers .
so that whichever customer pays for his selected course , he gets a link to only that course in the mail .

how do i use pabbly connect in this case , please help.
regards

Option 1 - Setup Routers based on Prices of the course's product link. Two courses can't have same pricing.

Option 2 - Use Payment Pages instead and try to follow this video, which does not setup router using pricing so you can have two course with same pricing. https://www.berrycast.com/conversations/4d59a8d4-e234-5b72-a469-9ed364743050
