Payment Links for Research Peptide Orders

When a payment link makes sense

An eligible merchant can use a hosted payment link when an order is quoted by staff and the customer should enter payment details in a browser. A link can carry a fixed amount or reference to the order, depending on what the provider supports.

Decide who owns the order record

Create the order or invoice first and include a unique reference in the payment flow. Keep its status pending until the provider confirms the result. If staff resend links, define when an old link should expire to prevent a customer paying twice.

Example: a revised wholesale quote

When a buyer accepts a revised quantity, create the new invoice and payment request with the revised total. Make the earlier link unavailable if your provider supports cancellation. If the buyer already paid the first invoice, reconcile the existing payment and send only the amount still owed or initiate the relevant credit.

Ask about link behavior before sharing one

• Whether the gateway can set amount, expiry, use count, and the invoice reference.
• How to identify an abandoned, expired, or completed link.
• Where refund requests go and what the buyer will see on the receipt.
