Payment gateways for online stores in India and Oman: Razorpay, Stripe and Thawani
How online payments work, how to choose a gateway for India or Oman, and what a developer needs to get right when integrating one.
Tech guideA payment gateway is what lets your website accept cards, UPI and wallets securely. Picking one is part business decision — fees, settlement, supported methods — and part technical: a careless integration can mark orders as paid when they aren't, or miss payments that did go through.
How an online payment actually works
When a customer checks out, your site creates an order with the gateway and hands the customer to the gateway's secure payment page or popup. The customer pays, the gateway confirms with the bank, and then tells your site the result.
Your website never sees or stores card numbers — the gateway handles that, which is why it carries the PCI DSS compliance burden rather than you. Your job is to create the order correctly and trust only a verified confirmation from the gateway.
Choosing a gateway in India
For businesses selling to Indian customers, Razorpay is the most common choice: quick onboarding, support for UPI, cards, net banking and wallets, and good developer tools. Cashfree, PayU and CCAvenue are solid alternatives worth comparing on fees and settlement time.
UPI support is essential — it's how a large share of Indian customers prefer to pay. Check current rates on each provider's site, since fees vary by payment method and change over time.
Choosing a gateway in Oman and for international sales
For stores in Oman, Thawani Pay is a local gateway that supports Omani debit cards and settles in rials, which is why we used it for Ads.om. Bank-provided gateways are another option for larger merchants.
If you sell internationally in several currencies, Stripe is the strongest developer platform, with subscriptions, invoices and many local payment methods. Availability and onboarding requirements depend on where your business is registered, so confirm eligibility first.
What a good integration gets right
Verify every payment on the server. The browser redirect after payment can be faked or interrupted, so the order should only be marked paid once the gateway's signature is verified or a webhook confirms it.
Handle webhooks reliably. Customers close tabs and lose connection mid-payment; webhooks let the gateway tell your server about the payment anyway. Make them idempotent so a repeated notification doesn't create duplicate orders, and log everything so support staff can trace a payment.
Plan for refunds, partial payments and failures from the start, and test them in the gateway's sandbox before going live.
Cash on delivery and payment links
Many stores still need cash on delivery alongside online payment, and some sell mostly over WhatsApp or Instagram. Payment links from the same gateway let you collect online without a full checkout, and they show up in the same dashboard as website orders.
Frequently asked questions
Which payment gateway is best for a small business in India?
Razorpay is a common starting point because onboarding is quick and it supports UPI, cards and wallets. Compare fees and settlement times with Cashfree and PayU for your volume.
Do I need PCI compliance for my website?
If you use a hosted checkout or the gateway's popup, card data never touches your server, so most of the burden sits with the gateway. You still need HTTPS and to follow the gateway's integration rules.
Can you add a payment gateway to my existing website?
Yes. We integrate Razorpay, Stripe and Thawani Pay into existing sites and apps, including server-side verification, webhooks and refunds.
