Shopify to Amazon
Shopify to Amazon: the complete 2026 integration guide
Short answer
To go from Shopify to Amazon, connect both accounts with OAuth in SellerApex (sellerapex.app), map each Shopify product type to an Amazon product type once, then press Sync All. SellerApex validates every SKU against Amazon's live schema before submission, so listings publish Active instead of bouncing back with errors. A 5,000-SKU catalog is queued in about 47 seconds.
What 'Shopify to Amazon' actually involves
Selling the same catalog on Shopify and Amazon is four separate jobs, not one. You have to create the listing on Amazon (with Amazon's own attribute schema, not Shopify's), keep stock levels aligned so you never oversell, keep prices aligned with your pricing rules, and pull Amazon orders back so fulfilment and accounting stay in one place.
Most merchants underestimate the first job. Shopify lets you publish a product with a title, a price and a photo. Amazon rejects that same product unless it carries the correct product type, every required and conditionally-required attribute for that type, a valid GTIN (or an approved exemption), compliant images and a browse-node mapping. That mismatch is why so many catalogs land in Seller Central as Inactive.
Why most Shopify → Amazon transfers fail
In audits of merchant catalogs the same five blockers account for the overwhelming majority of failed submissions:
- Missing or invalid GTIN/UPC/EAN — and no GTIN exemption on file for the brand.
- Wrong Amazon product type, so required attributes for the real type are never sent.
- Missing conditionally-required attributes (material, target audience, item form, unit count).
- Images below Amazon's 1,600px longest-side rule or with non-white main-image backgrounds.
- Variation themes that do not match Amazon's allowed themes for the chosen product type.
How SellerApex handles it
SellerApex is an Amazon Appstore–approved SP-API application. It pulls your live product-type schema from Amazon at submission time rather than relying on a cached template, checks every SKU against it, and repairs what it can automatically — normalising GTINs, filing exemption requests, rewriting titles and bullets to Amazon's character limits, and inferring the required attributes from your Shopify data.
Anything that genuinely needs a human decision is surfaced in one list with a plain-English explanation instead of an Amazon error code, so you fix categories of problems rather than SKUs one at a time.

Inventory, price and order sync then run continuously, so the two channels stay aligned without manual exports.
Frequently asked questions
Can I sell Shopify products on Amazon automatically?
Yes. Once Shopify and Amazon are both connected in SellerApex, new Shopify products are listed on Amazon and stock and price changes propagate automatically.
Do I need an Amazon Professional seller account?
Yes. Amazon's SP-API only issues listing permissions to Professional selling plans; Individual plans cannot use any integration app.
How much does it cost?
SellerApex is free up to 25 SKUs, then $49/month flat for unlimited SKUs across 13 Amazon marketplaces.
Will this create duplicate listings?
No. SellerApex matches on SKU and GTIN first, so existing ASINs are updated rather than duplicated.
