Nembol API

One API for every channel you sell on

Create products once, publish them to Shopify, Amazon, eBay, Etsy, TikTok Shop and more, keep stock in sync and read every order in one shape, for your own store, for hundreds of sellers, or from your AI agent.

Things to know first

Before your first call

Access: the API comes with the Enterprise+ plan (partners: with the partner agreement). Keys are created in Settings → Developers. During the free trial, on any plan, you can use test keys and one webhook endpoint.
Test without risk: nbl_test_ keys check and simulate every call; partners also get a sandbox that runs for real and is never billed. See Test your integration.
One shape everywhere: prefixed ids (prod_…, acct_…), one error envelope, cursor pagination, Idempotency-Key on every write.
Irreversible actions ask first: delist, disconnect, close a company or refund a storefront order answer 409 confirmation_required with a token (shipping an order doesn't ask: warehouse automations ship unattended). Repeat with Nembol-Confirmation. Most changes can be undone for 30 days.
The rules that matter (variants, texts per channel, images, orders, tracking) are on one page: Rules and limits.
