Dunnes Stores API — Real-Time Ireland Grocery Data
Access Dunnes Stores' Irish grocery catalog via the Pepesto API — live pricing in EUR, product availability, nutritional data, and full catalog coverage from dunnesstoresgrocery.com, returned as structured JSON.
What Does the Dunnes Stores API Return?
Everything visible in the Dunnes Stores app and website, returned as clean JSON via a single REST call.
Dunnes Stores-specific: Promotional prices listed on dunnesstoresgrocery.com are captured in each daily refresh.
Why Use an API Instead of Building Your Own Dunnes Stores Integration?
Developers who have tried to build their own Dunnes Stores data pipeline know the obstacles. Unofficial workarounds exist, but they come with real costs.
Dunnes Stores updates their website regularly — changing markup, adding rate limiting, or restructuring categories. Pepesto absorbs all of that. Your integration keeps working.
The same JSON field names work whether you're calling Dunnes Stores, Albert Heijn, Tesco, or any other supported chain. One integration for all of Europe.
Calling a REST API takes hours. Building, maintaining, and scaling your own Dunnes Stores data extraction takes months — and requires ongoing engineering resources.
DIY data extraction is fragile: a single layout change can silently break your pipeline. Pepesto monitors and updates integrations continuously so you don't have to.
