Wehkamp Integration: Marketplace API, Fashion & Living Centralized Management

About Wehkamp: History, Ownership and Market Position

History (1952 – Today)

Wehkamp was founded in 1952 in Slagharen, Overijssel, by Herman Wehkamp as a mail-order catalogue business serving rural Dutch households. For decades, the Wehkamp catalogue — known affectionately as "het boek" ("the book") — was a fixture in millions of Dutch homes, comparable in cultural significance to La Redoute in France or Otto Versand in Germany. Wehkamp moved its headquarters to Zwolle and successfully transitioned from print catalogues to e-commerce in the early 2000s, becoming one of the Netherlands' first true omnichannel retailers.

In 2014, private equity firm Apax Partners acquired Wehkamp from RFS Holland Holding, investing in digital transformation and logistics. Wehkamp launched its third-party marketplace, Wehkamp Plus, in 2018 — the same year Otto Group (Hamburg, Germany) acquired the company, integrating it alongside sister brands Bonprix and the Hermes logistics network. Today Wehkamp operates a high-bay distribution centre in Maurik (Gelderland), one of the most automated DCs in Europe.

Wehkamp Ownership Structure (2026)

• Otto Group (Hamburg, Germany) — 100% owner since 2018, parent company
• Bonprix — Sister brand (Otto Group fashion vertical)
• Hermes Group — Sister logistics provider (Otto Group)
• Wehkamp B.V. — Operating entity, headquartered in Zwolle
• Apax Partners — Previous owner (2014–2018, exited)

Position in Dutch E-Commerce

Wehkamp is one of the top 5 e-commerce destinations in the Netherlands, behind Bol.com and Amazon.nl but ahead of Coolblue in fashion and home & living share. With deep brand equity built over seven decades, Wehkamp is particularly strong in women's fashion, family fashion and home furniture — categories where Bol.com and Amazon historically under-index. The company's mail-order heritage gives it disproportionate trust among consumers aged 35+ in suburban and rural NL.

Wehkamp Sales Volume and Scale (2024–2025 Data)

Wehkamp's transition from heritage catalogue retailer to omnichannel marketplace has produced consistent annual GMV growth of 8–14%, despite the broader contraction of Dutch e-commerce post-2022. Wehkamp Plus, the 3P marketplace launched in 2018, now represents an increasing share of platform-level GMV.

Year	GMV (EUR)	Orders	Active Customers	3P Sellers
2020	~€520M	14M	3.8M	250
2022	~€620M	17M	4.6M	520
2024	~€700M	19M	5M+	800+
2025 (estimate)	~€780M	21M	5.4M	1,100

Growth is driven by the Otto Group logistics integration (Hermes parcel network in DACH cross-border), the Maurik DC automation upgrade, and Wehkamp Plus' expansion into home furniture, beauty and baby. Becoming a Wehkamp Plus seller remains one of the most under-priced organic growth channels in the Benelux for fashion and living brands.

Becoming a Wehkamp Seller (2026 Current Rules)

1. Legal and Financial Requirements

To sell on Wehkamp Plus you must hold an active Dutch (or EU) business registration with a verified VAT number. Otto Group applies a rigorous quality bar — onboarding can take 14–28 days.

• KvK registration (Kamer van Koophandel) or equivalent EU business registration
• BTW-nummer (Dutch VAT number) — required for invoicing to NL consumers
• Verified IBAN — payouts are remitted to this account
• Peppol participant ID — for B2B UBL e-invoicing flows
• GDPR/AVG compliance statement and AP (Autoriteit Persoonsgegevens) notice readiness
• REACH/CE/WEEE compliance — mandatory for cosmetics, toys, electronics
• Wecycle producer registration for WEEE/battery categories
• Trademark registration (preferred) for brand-owner status

2. Wehkamp Plus Seller Application

You apply through verkopen.wehkamp.nl, the official seller portal. Approval typically takes 14–28 business days because Otto Group runs brand-protection, financial-stability and quality-of-content checks. Upon approval you receive a seller ID, OAuth 2.0 client ID and client secret for the Wehkamp Marketplace API — these credentials drive every integration call.

3. Product Listing and Content Rules

Wehkamp inherits Otto Group's strict content standards, especially in fashion and home & living:

• Title: 40–120 characters, brand + product + key attribute (size/color/material)
• Images: White background, minimum 1200×1200px, up to 6 photos, no watermarks or text
• Description: HTML supported, minimum 250 characters with structured attribute callouts
• Category mapping: Wehkamp taxonomy ID + attributes (color, size, material, care label)
• EAN/GTIN: Mandatory for fashion and home; enables Otto Group catalogue matching
• Content score: Minimum 75+ — listings below threshold are not surfaced in search

Wehkamp Commission Rates (2026)

Wehkamp 2026 commission rates range from 8% to 22% by category, plus 21% Dutch BTW on the commission fee, fulfillment fees and shipping. Wehkamp Plus has no monthly subscription — sellers pay commission only on completed orders. The three commission bands are:

Net margin formula: Selling price − Wehkamp commission − 21% BTW on commission − Fulfillment fee − Shipping − COGS = Net profit. Zunapro's pricing module computes this per SKU per category in real time, blocking listings that would dip below your minimum margin threshold.

Wehkamp Marketplace API — Technical Details

The Wehkamp Marketplace API is a RESTful interface that lets sellers programmatically sync products, stock, prices, orders, shipments and returns with Wehkamp's seller systems. Base URL: https://api.wehkamp.nl/marketplace/. Full documentation is published at developers.wehkamp.nl.

API Authentication

Wehkamp uses OAuth 2.0 client_credentials grant. You exchange your client_id + client_secret at /oauth/token for a bearer token with a 1-hour TTL. Tokens are scope-restricted per resource (products, orders, shipments). Zunapro handles token refresh, retry and scope negotiation automatically.

Main Endpoint Categories

• Catalog API — Product creation, variant management, attribute mapping, content score lookup
• Inventory API — Stock and price sync (bulk endpoint up to 250 SKUs per request)
• Orders API — Order listing, status updates, package creation, accept/reject
• Shipments API — Label generation, PostNL/DHL Parcel track-and-trace push
• Returns API — 14-day right-of-withdrawal flows, refund processing
• Settlements API — Earnings statements, commission breakdown, BTW reports
• Webhooks — Order, stock and return events delivered via signed HTTPS callbacks

Rate Limits and Error Handling

The Wehkamp API rate limit is approximately 10 requests per second per seller account, with burst tolerance up to 30 rps. Exceeding it returns 429 Too Many Requests. Common error codes: 400 (invalid attribute payload), 401 (token expired), 404 (EAN/category not found), 422 (validation), 500 (Wehkamp-side — retry with backoff). Zunapro's integration handler implements exponential backoff, idempotency keys and a dead-letter queue.

Wehkamp Catalog Import — Bulk Product Onboarding

Beyond the REST API, Wehkamp supports CSV and XML bulk upload via the seller portal. For SMB sellers migrating from Shopify, WooCommerce, Magento or supplier feeds (common with fashion wholesalers in Amsterdam, Eindhoven and the Antwerp diamond corridor), Zunapro's catalog import module automates the conversion.

Wehkamp Catalog Schema (Key Fields)

• productMainId — Master SKU that groups variants (size, color)
• brand, title, productCode, stockCode, ean
• categoryId (Wehkamp taxonomy), attributes (color, size, material, care)
• quantity (stock), listPrice, salePrice, vatRate (21% / 9%)
• shippingProfileId, warehouseId, handlingTime
• images (1–6 HTTPS URLs), description (HTML)

From Supplier Feed to Wehkamp Live

Most European wholesale suppliers (especially in fashion and home) publish XML/CSV feeds. Zunapro's import module:

1. Reads the supplier feed URL on an hourly or daily cron schedule
2. Learns category mapping (manual first time, AI-suggested afterwards)
3. Normalizes attributes (brand, material, color naming, EU size charts)
4. Adds margin + commission + BTW to compute the Wehkamp selling price
5. Tracks supplier stock — automatically deactivates SKUs that go OOS upstream
6. Pushes to Wehkamp via API with idempotency guards

Wehkamp Fulfillment — Logistics Options

Unlike Bol.com (LVB) or Amazon (FBA), Wehkamp does not currently run a fully-managed FBA-style program for 3P sellers — Wehkamp's own Maurik DC handles only first-party (1P) inventory. 3P marketplace sellers fulfill orders themselves via approved carriers, with Otto Group's Hermes network available for DACH cross-border expansion.

Approved Wehkamp Shipping Carriers

• PostNL — Primary parcel carrier, next-day delivery NL-wide
• DHL Parcel Benelux — Secondary parcel + B2B options
• XPO Logistics — Heavy furniture (sofas, beds, dining tables, wardrobes)
• Van Straaten — Specialist white-glove furniture delivery with assembly
• Hermes Group — Otto Group sister carrier for cross-border DACH

Shipping Cost Guidance (2025)

• Parcel (PostNL/DHL): €4.50–€7.50 per parcel (NL domestic, <10kg)
• Heavy items (XPO): €25–€85 per delivery, by weight + volume
• White-glove (Van Straaten): €60–€150 incl. room-of-choice + assembly
• Returns: 14-day Dutch consumer right; sellers usually cover return parcel cost

For sellers shipping 500+ orders per month, negotiating a PostNL contract directly via Wehkamp's reseller programme can reduce parcel cost by 20–30%.

Wehkamp Seller Score and Cancellation Rates

Wehkamp assigns every Plus seller a 1–10 seller performance score that directly influences search visibility, badge eligibility and Buy Box wins. Otto Group's quality bar makes these thresholds stricter than Bol.com's or Amazon's.

• Cancellation rate — Stock-out cancellations are the largest penalty; >2% triggers warning, >5% triggers account review
• Late shipment rate — Orders not handed to PostNL/DHL within the promised handling time
• Return rate — Fashion category accepts ~25–35% returns as natural; outliers trigger review
• Customer review score — Must stay above 4.0/5
• Response time — Customer messages must be answered within 24 hours (NL business days)

Zunapro's real-time stock sync reduces cancellation risk by ~90% — the moment a unit sells on your webshop, Bol.com or Amazon.nl, the Wehkamp listing is decremented or paused.

Wehkamp Advertising, Promotions and Smart Pricing

Wehkamp Ads

• Sponsored Products — CPC bidding on search keywords inside wehkamp.nl
• Brand campaigns — Banner and display in fashion/home category pages
• Wehkamp Outlet promotions — Seasonal sale events with elevated visibility
• Wehkamp Plus subscription targeting — Reach customers in the consumer loyalty program

Smart Pricing (Repricer)

When multiple sellers list the same EAN, Wehkamp shows a Buy Box winner based on price, seller score and handling time. Zunapro's repricer adjusts prices in seconds based on competitor moves, while respecting your minimum margin floor and category-specific commission bands.

Wehkamp Peppol UBL E-Invoicing (Dutch Legal Compliance)

Dutch B2B transactions require Peppol-compliant UBL e-invoices, and the Belastingdienst (Dutch tax authority) increasingly expects digital VAT reporting. For B2C consumer orders, structured email invoicing with VAT breakdown is the standard. Manual invoicing is unsustainable beyond 50 orders per day.

Zunapro's e-invoicing module:

• Generates Peppol UBL 2.1 invoices automatically the moment a Wehkamp order is paid
• Routes through certified Dutch Peppol access points
• Issues automatic credit notes (creditnota) on returns within the 14-day withdrawal window
• Produces monthly BTW (VAT) reports compatible with Belastingdienst filing
• Emails the PDF invoice + UBL XML to the customer automatically
• 2-year statutory warranty (garantie) tracking per SKU per buyer

Wehkamp Shipping Integration — PostNL + DHL Parcel + Furniture Specialists

Wehkamp orders default to PostNL for parcels (next-day NL-wide via the green PostNL network) and DHL Parcel Benelux for higher-volume sellers. Heavy goods route via XPO Logistics or Van Straaten for white-glove furniture delivery, and Otto Group's Hermes Group handles cross-border DACH expansion.

Zunapro's multi-carrier module auto-selects the right carrier per order based on weight, volume, dimensions, destination postcode and customer preference; prints labels; and posts track-and-trace back to Wehkamp via the Shipments API in real time.

Wehkamp Returns and Customer Service Management

Dutch consumers enjoy a statutory 14-day right of withdrawal (under EU Consumer Rights Directive, transposed into Dutch BW Boek 6) on all distance sales. Fashion return rates are typically 25–35%, home & living 10–15%, beauty 5–8%. Mismanaging returns crushes seller score.

Standard Wehkamp Return Flow:

1. Customer initiates the return in the Wehkamp consumer app (within 14 days of delivery)
2. Wehkamp/PostNL collects the parcel free of charge for the customer (1–3 business days)
3. The parcel arrives at a return processing centre; condition assessment is logged
4. Seller has 1–3 business days to approve or contest the return
5. On approval, Wehkamp refunds the customer via the original payment method

Zunapro's returns module tracks every step, fires panel notifications to the seller, auto-issues the creditnota UBL invoice, and updates inventory if the item is restock-grade.
