Getting started

Create a token, make your first call, and understand what the API can reach.

FLUF connects one account to every marketplace it supports. This API lets your own system drive that: list an item everywhere, change a price, find out what sold — without writing a single marketplace integration or ever touching marketplace credentials.

Base URL: https://fluf.io/wp-json/fc/api/v1

Get a token

  1. In FLUF Connect, open More → Developers (open it)
  2. Under API tokens, name the token (e.g. "Inventory sync") and click Create token
  3. Copy it. It's shown once and starts with fluf_pat_

Send it on every request:

Authorization: Bearer fluf_pat_xxxxxxxxxxxx_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

API access comes with the plan. There's no separate developer tier and no per-call fee. Seller plans get read-only access, and Pro and above get read and write. Starter has no API access. See What's supported.

A token can do everything your plan allows, publishing and delisting included on Pro. Store it like a password and keep it server-side. Create a separate token for each integration so you can revoke one without touching the others.

There's no sandbox. Every write acts on real marketplace listings. Testing describes a safe way to try things out.

Your first call

Ask which marketplace accounts you can publish to:

curl "https://fluf.io/wp-json/fc/api/v1/accounts" \
  -H "Authorization: Bearer fluf_pat_your_token"

Each account comes back with an id like ebay:718 — the marketplace, then the connection. That id is what you name as a target when you publish. A seller with two eBay accounts has two entries, and they are not interchangeable.

The shape of it

GET /accountsThe marketplace accounts you can publish to
POST /productsCreate a product from photos and details
POST /products/importCreate products in bulk from a CSV or Excel file
PATCH /items/{vid}Edit a product; its live listings follow
POST /itemsPublish a product to marketplaces, or reprice one account
DELETE /itemsTake listings down on the accounts you name
POST /items/{vid}/mark-soldReport a sale made elsewhere; delists everywhere
DELETE /items/{vid}Delete the product
GET /itemsReconciliation sweep, with updated_since for catching up
GET /items/{vid}One product's state on every account

Full request and response shapes are in the REST API reference.

Create a product, publish it, edit it, and it sells: that whole cycle runs through the API. Reading and replying to buyer messages doesn't. What's supported lists what the API covers and what it doesn't.

What a vid is

Products are addressed by a vid — a stable string identifying one product, whichever system it came from:

shopify_8123456789012_0     a product sourced from Shopify
fluf_326428506_0            a product created in FLUF

You'll see vids in every response. Pass them back verbatim; don't parse or construct them.

Know when something happens

Polling works, but you'll be late. Register a webhook and FLUF will POST to you the moment an item sells, a listing goes live, or a buyer messages you (on Depop and Vinted).

See Webhooks to register one and verify the signature, and the event reference for everything we send.

When you fall behind

If your endpoint was down, or you never saw a response, don't try to replay events — ask for current state:

curl "https://fluf.io/wp-json/fc/api/v1/items?updated_since=2026-08-01T00:00:00Z" \
  -H "Authorization: Bearer fluf_pat_your_token"

That returns only products that genuinely changed, so it stays quiet when nothing happened. It's the backstop for any gap: an outage your side, a bug in your consumer, or a cold start.

Machine-readable

Two OpenAPI documents, both public — no token needed to read them:

Point a client generator at either.
