Introduction

The Content Egg Billiger.de module lets you integrate product offers from Billiger.de into your website.

Billiger.de is structured around three entity types:

Base products → Products → Offers

When you search by keyword, Billiger.de may return either base products or products, depending on the selected search settings. Content Egg then resolves these results into actual shop offers, so the saved entries always include offer-specific information such as price, merchant, and availability.

Search Result Type Setting

In the module settings, you can choose the default Search result type.

This setting determines which Billiger.de entity type is searched first when using keyword-based search. Regardless of whether the initial match is a base product or a product, Content Egg always converts the result into a concrete shop offer before saving it.

Best Practice

We recommend searching by direct base product or product URL whenever possible, as this usually provides the most accurate match.

Supported URL formats include URLs containing baseproducts or products, for example:

• https://www.billiger.de/baseproducts/110057-apple-macbook-air-m4-2025

• https://www.billiger.de/products/5442274125-sony-playstation-5-slim-digital-edition-fortnite-flowering-chaos

EAN Search

The module also supports search by EAN.
