The API is available to advertisers and business partners only. The advertiser has ownership to his ad, therefor we can not allow third party usage. However, we would like nothing more than to expose APIs to "open data" as soon as there are any available.
API-access is a product any advertising organisation may include in his business relationship with FINN. Please, instruct the customer to contact his business contact at FINN to verify API-access and order an API-key. Then, both you and the customer will recieve the API-key.
The new API uses api.finn.no URLs and a custom header for authorization. The old and discontinued API uses IP-address for authorization and finn.no/rest URLs.
There is an iframe solution available. However, iframe has some issues with vertical scrolling and poor user experience on mobile. The API allows you a seamless integration with custom styling.
There is a PHP demo client in GitHub. We plan to add code samples in node.js, Java and Scala in the future.
Our evolution strategy is Graceful degradation over versioning: Data will change continuously (fields come and go) but the semantics of the API should not break.
Please see the image sizes API reference for more information.
The APIs are used by internal applications such as www.finn.no, native apps, integration partners and a large number of customers such as real-estate agents, car dealers, boat dealers etc.
