What to know when setting up online payments
Checkout is the most fragile point of a purchase. Built well it lifts sales; built badly it empties the basket.
01Offer the method your customer expects
Payment preferences differ by country and by sector. In Türkiye, instalment options alongside card payment are decisive in many categories. Not finding the expected method is a reason to abandon that has nothing to do with price. Knowing how your audience is used to paying comes before any technical choice.
02Don't hold card details yourself
Storing card data on your own systems is a serious responsibility and an unnecessary risk. When you use the payment provider's secure page or fields, that data never touches you and your obligations stay minimal. This is not a technical preference but a decision that protects your business.
03Design the failed payment too
Some payments always fail: insufficient limit, a verification error, a dropped connection. Tell the user plainly what happened and make retrying easy. An error screen that empties the basket and sends the user back to the start loses a sale you had already won.
04Verify on the server
The only reliable proof that a payment completed is the signed notification sent from the payment provider to your server. The user reaching the success page is not evidence. Confirming the order on that notification is the right approach for both accounting and abuse prevention.
