What is a payment gateway?

A payment gateway is the service that connects your checkout to the customer’s bank, card network or UPI app, so money can move securely when someone pays. It decides whether the payment goes through. It is not the shop itself.

Updated 6 October 2026

A payment gateway is the service that securely passes a customer’s payment details from your checkout to their bank and returns the result, so you know it was paid.

Selling and payments

What a gateway does

Razorpay’s documentation describes a payment gateway as a secure pathway between a customer and the business, which involves authenticating both parties with the banks involved. In practice that means four steps happen in a few seconds: the buyer picks how to pay, the gateway passes the details to the bank or card network, the buyer proves it is them (a PIN, a one-time code), and the result comes back to your shop as paid or failed.

The money does not land in your account at that moment. Gateways settle it to you later in batches, and their dashboards report payments, refunds and settlements so you can reconcile them against your own records.

The methods on offer depend on the gateway. Razorpay’s page lists cards, netbanking, UPI, cash on delivery, EMI and wallets such as Paytm and PhonePe. A different gateway will list a different set.

Gateway, checkout page and payment link are different things

Razorpay’s documentation says you should consider integrating its gateway if you have a website or a mobile app, and points sellers without one to Payment Links and Payment Pages. It also describes four checkout styles for developers: Standard (a customisable Pay button), Custom (you design the whole flow), Quick (an auto-generated button) and server-to-server.

What to check before you pick one

  • Which payment methods your buyers actually use, UPI first if you sell in India.
  • What is needed to open the account. Gateways ask for business details and identity documents, so start before you need to take the first order.
  • How refunds work and what they cost. Read the refund rules, not only the pricing page.
  • How long settlement takes, and whether you can download a report to match payments to orders.
  • What happens when a payment fails: does the buyer see a clear error and a way to try another method?

If you sell through Instagram DMs, the practical test is whether the buyer can pay from a link without leaving a trail of manual steps for you. The DMFast store, available in India only, takes payments through Razorpay, and DMFast itself takes no fee on sales. Razorpay’s own charges are set in your Razorpay account, so check them there.

An example

A yoga teacher sells a PDF routine for a flat price. She shares a hosted payment page in a DM; the gateway handles the UPI or card step, then tells her the order is paid, so she doesn’t have to check her bank app.

Questions people ask

Is a payment gateway the same as a payment processor?

Not exactly. The gateway collects and passes on the payment details at checkout; the processor works with the banks to move the money. Many providers bundle both, so sellers usually deal with one company, and the terms are often used loosely.

Do I need a website to use a payment gateway?

Not always. Razorpay’s documentation says sellers without a website or mobile app can still accept payments through products such as Payment Links and Payment Pages. Other providers have similar tools, so look for hosted pages.

Does a gateway hold my money?

It receives the payment first and then settles it to your bank account on a schedule. How long that takes and what is deducted varies by provider, so read the settlement terms before you rely on a date.

What is a checkout?

It is the screen where a buyer picks a payment method and confirms. The gateway runs behind it. You can use the provider’s standard checkout or, if you build your own site, design a custom one.
