Processors & gateways
Bring your own processor
MerchantLink sits on top of the payment processor or gateway you choose. Your money settles directly with them. You get one pay page, one dashboard and one API across all of them.

Beta integrations are built against each provider’s published API and are being certified in their sandboxes. Payment method availability depends on your processor account and the payer’s device.
MerchantLink Sandbox
Every account starts with a built-in test processor, so you can try the full invoice → link → pay flow before connecting a real one.
How it works
Switch or add processors without changing a thing
Your invoices, links, QR codes and API integrations don’t care which processor is behind them.
Connect in minutes
Smart routing
Many at once
Always in sync

Every account starts with a built-in sandbox, so you can create invoices, send links and take test payments before you connect a processor.
