Connect Shopify and Lazada in under 10 minutes with OneCart's guided setup.
Shopify is your own branded storefront, while Lazada reaches a large marketplace audience across Southeast Asia. OneCart connects the two so one inventory pool feeds both and every order, from the storefront and the marketplace, lands in a single dashboard.
Shopify and Lazada share one stock pool in OneCart. A sale on Shopify reduces the matching SKU on Lazada, and a Lazada sale does the same in reverse, so your storefront and the marketplace never promise stock you have already sold.
Orders from Shopify and Lazada are brought into OneCart automatically and arrive in one dashboard, so you handle fulfilment from a single queue instead of logging into each platform.
Build a product once in OneCart and create it on Lazada from Listings > New, including an HTML description, which Lazada accepts. Map the Variant SKU in OneCart to the Seller SKU in Lazada so stock and orders line up between the two.
Connect Shopify: go to Settings > My Platforms > Manage Connections and click Add shop for Shopify. Install the OneCart app when Shopify prompts you, log in to the Shopify store, then log in to OneCart. A green banner confirms Shopify is connected.
Connect Lazada using its 2024 method. Open the Lazada Marketplace page for OneCart in your store's country, select 'Authorization Only' and 'Half a year', agree to the terms, then enter your Lazada Seller Centre login. Repeat for each Lazada store you run.
Keep the Lazada link healthy. Lazada authorisations expire, so if Lazada Seller Centre shows an expiry date that differs from OneCart, open the shop's Settings page in OneCart and click the yellow Update Lazada Expiry Date button.
Build a product once in OneCart and create it on Lazada from the same screen, including an HTML description, rather than re-entering everything in Lazada Seller Centre.
A sale on Shopify reduces the matching SKU on Lazada in real time, so your own site and the marketplace never promise stock you have already sold.
Everything you need to know about connecting Shopify and Lazada with OneCart.
Shopify installs the OneCart app and you log in once. Lazada's 2024 method is multi-step: open the Lazada Marketplace page for OneCart, choose Authorization Only and Half a year, accept the terms, then log in to Seller Centre. Each Lazada store is authorised separately.
Lazada API authorisations expire. Check Settings > Third Party Apps in Lazada Seller Centre for the expiry date. If it differs from what OneCart shows, open the shop's Settings page in OneCart and click the yellow Update Lazada Expiry Date button.
Lazada is connected per store using its 2024 method, where you open the Lazada Marketplace page for OneCart in your store's country and authorise each store one by one. If you run more than one Lazada store, you repeat the step for each.
OneCart has plans for different sales volumes and channel counts. The current tiers and what each includes are on the /pricing/ page, which is the best place to see the latest options for a Shopify and Lazada setup.
