Executive Summary & Commercial Scope

Blueboynl Automator is a Dutch marketplace automation extension engineered by Pasindu Piumal for a Netherlands-based e-commerce seller on Fiverr managing 200+ product listings across Bol.com (Netherlands' largest marketplace) and Marktplaats (classifieds). The seller was spending 45+ minutes manually listing each product on both platforms. The extension automates the full listing workflow: reads product data from a Google Sheet, generates platform-optimized listings, and publishes to both marketplaces automatically.

1. Bol.com Retailer API Integration

The extension integrates with Bol.com's official Retailer API to create product offers, update pricing, and manage inventory — using OAuth 2.0 client credentials flow for authentication. Bulk listing creation is handled via the offers/bulk endpoint with proper EAN validation and category classification.

2. Dutch Language Product Description Generation

For listings requiring Dutch descriptions, the extension uses GPT-4o with a Dutch language + marketplace-tone system prompt to generate compelling product descriptions from basic product attributes (name, specifications, condition). This ensures naturally-worded Dutch text rather than machine-translated content.

3. Cross-Platform Inventory Sync

When a product sells on either platform, the extension decrements the inventory count on both marketplaces simultaneously — preventing overselling between Bol.com and Marktplaats. Inventory state is stored in chrome.storage.sync as the source of truth and synced to both platform APIs within 60 seconds of a sale notification.

4. Adaptive Rate-Limiting & Cooldown Circuit Breaker

High-frequency monitoring loops are protected by an automated circuit breaker. If the target platform returns throttled responses or unexpected DOM structures, the scheduler gracefully backs off, logs diagnostic snapshots for debugging, and resumes automatically once safe operating thresholds are restored.
