Embed a checkout link

Pay Links are the fastest way to take a payment without sending the buyer through your full storefront. Useful for one-off sales, custom invoices, social DMs, and embedding on a partner's site.

Generate a link

Open Pay Links (or use the keyboard: Ctrl+K → "new pay link"). Pick a product or enter a custom amount. Optional: title, image, description, expiration date, max uses. Click Create.

You get a URL like sellstein.com/pl/abc123 plus a QR code and embed code. The link works on every device, supports every payment method you've enabled, and the buyer's confirmation lands in your Orders list with the same data as a normal storefront purchase.

Sharing it

Three ways:

• Direct URL. Paste it in a tweet, Instagram DM, email, SMS. Most-used pattern. Shortens automatically on platforms that compress
• QR code. For in-person, posters, restaurant menus, business cards. Download as PNG or SVG from the Pay Link detail page
• Embed code. Drop the iframe on any external site (a partner's blog, a landing page you built elsewhere). The checkout opens in a popover so the buyer never leaves the host site

Tracking the source

Every Pay Link can have UTM parameters baked in. Set them when you create the link or append them to the URL: `?utm_source=newsletter&utm_campaign=may2026`. The data shows up on the Pay Link's Stats tab and rolls up into your main Analytics view.

For deeper tracking, hit the link with `?ref=<your-id>` and we'll attach that ref to the order. Useful for affiliate or partner attribution where UTM is overkill.

Common patterns

• Custom invoice. Create a one-time link for a specific amount, send to one customer, expire after first use
• Limited drop. Set max_uses to your inventory, share publicly, the link auto-disables when sold out
• Subscription signup. Create a link tied to a recurring product. Buyer pays once, gets billed automatically thereafter
• Donation. Open-amount link with no max. Buyer chooses how much

What it doesn't do

Pay Links are not the same as your full storefront. They don't support upsells, cart cross-sells, or product bundles by default. Those still need the storefront flow. If you need a quick payment with no upsell, this is the right tool. If you're trying to build a whole product catalogue, use the storefront.
