About iyzico
iyzico is a Turkish payment technology company that lets online businesses take card payments through a single integration instead of dealing with each bank separately. It's best known for its Checkout Form product — a hosted, secure payment page that handles 3D Secure verification so merchants never touch raw card data. iyzico was acquired by PayU, the payments business of Prosus, in 2019, and is now one of the more established online checkout providers serving Turkish e-commerce.

How to apply for an iyzico merchant account
1. Create an iyzico account
Sign up on iyzico's site, then open the merchant application form from your control panel.
2. Gather your documents
iyzico asks for a signature circular, your tax registration certificate, ID copies for company partners, and an IBAN verification document (a bank statement or the cover page of your account passbook).
3. Check your website meets iyzico's requirements
Before applying, make sure your site has a privacy policy, a distance sales agreement, delivery/return terms, and an about page, plus an SSL certificate on any page that touches payment.
4. Submit and wait for review
Once every step of the application is complete, iyzico says its team typically reaches out by email within about a day.
5. Sign the agreement and collect your credentials
After approval, you sign a merchant agreement with iyzico and generate an API key and secret key from your dashboard — the two values TinyVendor needs.
Selling with iyzico on TinyVendor
Once your iyzico account is approved, connecting it to TinyVendor takes minutes, not a development project. There's no checkout page to build and no card data to store — iyzico's hosted page handles that part entirely, so you carry no PCI scope of your own.
1. Add iyzico as a gateway
In your TinyVendor dashboard, add iyzico and paste in your API key and secret key. Flip the sandbox toggle on while you test, then off when you're ready to take real payments.
2. Register your Back URL and server IP
iyzico only redirects buyers back to addresses it has approved. TinyVendor shows you the exact Back URL and IP to copy into your iyzico dashboard under Settings → IP/Back URL Management — do this before going live, or buyers will get stuck mid-checkout.
3. Create a sell link
Set a price and a description, pick iyzico as the payment method, and TinyVendor generates a link you can share right away — from a phone, with no coding involved.
4. Share it anywhere
Drop the link in a message, a bio, or an invoice. There's no storefront to set up first.
5. Buyer pays on iyzico's Checkout Form
Your buyer is redirected to iyzico, enters their card, and completes 3D Secure. TinyVendor then confirms the payment directly with iyzico's servers, so a manipulated redirect can't fake a sale.
6. See the order land in your dashboard
No spreadsheet, no manual checking — the paid order shows up in TinyVendor as soon as iyzico confirms it.
Selling outside Turkey too? Add Stripe or PayPal alongside iyzico on the same sell link setup.
