What Are Payment Links?
A payment link is a hosted checkout page with a fixed amount and a human-readable URL. Share it via email, WhatsApp, or embed it as a "Pay" button on your site. When the customer opens the link, a 20-minute deposit session starts automatically.
Creating a Payment Link
Go to Dashboard → Payment Links and click "New Link". Fill in:
- Name: Internal reference (e.g., "Invoice #1042")
- Amount: USDT amount to collect
- Description: Shown to the customer on the checkout page
- Redirect URL: Where to send the customer after payment
Click "Create" and your link is live instantly at paychainly.com/pay/your-slug.
Customizing the Checkout
Payment link checkout pages respect your account's invoice settings — you can add your company name, logo, and support email. These are set in Settings → Invoice Settings.
Tracking Payments
Each payment link shows its payment history in the dashboard. You can see which sessions were opened, which resulted in confirmed payments, and the transaction hash for each.
Using the API
Payment links can also be created programmatically:
POST /api/v1/payment-links
{
"name": "Invoice #1042",
"amount": 150.00,
"description": "Web development services — May 2025",
"redirectUrl": "https://yoursite.com/thank-you"
}When to Use Links vs. API Sessions
Use payment links for manual invoicing, donations, and simple checkout flows where you don't need real-time backend integration. Use API sessions when you need to programmatically link payments to orders in your system.
