An individual token is required to access the API. This token is available on request from the KfW coaches Matthias and Lorrain.
Use the frontend to create your own pre-applications and to better understand the data structure of the API response.
Use the Swagger API documentation to get to know the API.
With the API documentation as well as the access token, there is nothing to stop you from loading your own or already completed sample pre-applications. On request we will send you a list of about 100 prepared data sets, which you can load via the API.
There are no limits to your creativity. Find the most efficient and innovative way to transfer the loaded data into the systems of the banks / savings banks and process them there.
