E-Commerce Mobile App Integration: Same Stock, Same Orders as Your Site, in Your Own App

Without disrupting your existing e-commerce site, I build mobile apps that share products, stock, cart, accounts and orders through a common API and are published under your brand on iOS and Android.

Quick answerE-commerce mobile app integration shares an existing online store's product, stock, price, cart, account and order data with iOS and Android apps through an API, so both channels run on a single database. Hakan Sevimoğlu has built marketplace-integrated e-commerce software, a PayTR-integrated e-commerce platform for the paint industry, a furniture e-commerce system and an order panel integrated with Aras Kargo.

Why a mobile app?

You reach customers who install the app for free via push notifications: promotions, abandoned carts, price drops on favorites and shipping status. With saved cards and addresses, checkout takes just a few taps. The app is listed in the stores under your brand name.

How is the integration done?

  1. API: a REST API connected to your site's database is built; if your site has no API, one is added
  2. Sync: products, variants, stock, prices, promotions and categories come from a single source
  3. Accounts and cart: customers see the same account and cart on the site and in the app
  4. Payments: iyzico, PayTR or your bank's virtual POS, with 3D Secure
  5. Orders: orders placed in the app land in your site's admin panel and are handed to the carrier
  6. Notifications: push notifications for promotions and order status

Which platforms?

Your own software (PHP/Laravel, etc.), WooCommerce, OpenCart, Shopify and Turkish turnkey platforms such as ticimax/ideasoft; any system with API access can be integrated. Integrations with the Trendyol, Hepsiburada and N11 marketplaces (Turkey's leading marketplaces) and shipping carriers draw on the same stock as the app. For e-commerce infrastructure: e-commerce software.
