Authentication and Authorization

The ImmobilienScout24 API uses OAuth 1.0 for user authorization and API authentication. Applications must be authorized and authenticated before they can post or fetch data from ImmobilienScout24 or get access to member data.

For more detailed information on how the OAuth flow works, please visit this page here. We also have a Java tutorial.

Please also check third-party libraries in the open source community that abstract the OAuth 1.0 authentication process in many programming languages.
