Does FLUF have an API?

Yes. FLUF has a REST API and webhooks, authenticated with a personal access token you create in Settings. It is included with FLUF plans — read-only on Seller, read and write on Pro and above. There is no separate developer tier.

How do I get notified when an item sells?

Register a webhook for the new_sale event. FLUF sends a signed POST to your URL with your SKU, the marketplace it sold on, the price paid and the sale date — across every marketplace you have connected.

Can I use FLUF with Claude or Cursor?

Yes. In Claude, add FLUF as a connector (Customize → Connectors → Add custom connector, URL https://fluf.io/wp-json/fc/mcp) and sign in — nothing to install. For Cursor and other MCP clients, use the fluf-mcp npm package. Either way an AI assistant can read your inventory, list items to marketplaces, check your orders and ask FLUF's own assistant why something failed, all in plain language.

Does the API cost extra?

No. There is no per-call fee. Read-only API access is included with the Seller plan; publishing, repricing, delisting and webhooks need Pro or above. Starter does not include the API.

Developers

Connect FLUF to your system

One integration instead of fifteen. Publish to every marketplace your account is connected to, and know the second something sells — without touching a single marketplace API.
