I just saw this video from Shaun back in 2021 that shows the ability to set an expiration date for a payment link https://www.youtube.com/watch?app=desktop&v=tfZc07gXYQg, but I have been told that the feature was discontinued. I have a number of potential clients that would buy from us, but their business model makes it so they have to be able to expire links on a specific date and not allow payments after that date.
