Energy Efficiency leads delivery

This API allows customers with Lead contracts providing them with Solar, Energy Advisory, Heating/Heatpump, Window or RoofWindow leads to access those leads.

By default, those leads are delivered to the customer via email(s). Customers can also choose to pull Leads via our esgLeads API or alternatively get a notification pushed into their system using our webhook integration.


In order to use any of these methods:

  • the customer needs to have a contract with ImmoScout24 for the delivery of leads.
  • the customer or 3rd party vendor managing the receiving system needs to have valid client credentials (system key and secret).
  • In order to access the poll API or to register a webhook, the calling system needs to have a valid 3 legged OAuth1 token connecting the system to the customer's account which owns the contract.
