Show HN: Advanced Stripe Payment Links

Stripe payment links are great but they're currently missing some functionality which would make them even better.

I've built a no code payment link builder which extends standard Stripe payment links with some advanced functionality, such as:

Taxes - enable auto collection and extended tax id capture Currently you can't add a tax rate to a Stripe payment link, let alone enable the new Stripe Tax auto collection feature. I've fixed this so that you can enable it by simply switching a toggle. You can also enable tax id capture and choose a broader set of countries to capture from.

Dynamic customer lookup by param One of the (very) few annoying things with Stripe is that a duplicate customer will get created for every successful checkout unless the session is initialized within the context of that customer. To fix this you need to assign a customer pre-checkout but you can currently only do that programatically. I've fixed this so that now you can create a payment link, pass an email param (or customer id) and we'll do the customer lookup dynamically. If we find the target customer, we'll init a checkout session for them. No more dupe customers!

Other things I've added support for:

- Multiple prices - Funnel and conversion analytics - Custom redirects - Set any payment method option - Multiple products - Digital asset delivery post checkout - Branded links - Pre-applied coupons - no more copy and paste coupon codes - Custom metadata for social previews - Free form price amounts - One click unsubscribe billing management for customers - Seamless test link mode (just add /test/ to the url when enabled, no need to create test products, prices etc.)

Also there's an API in the works so if you're interested, add your email to the waitlist.

All feedback welcome!

This is very neat. I love the design. Stripe should hire the author on the stripe payment link team (if they want to be hired that is).
