To use the api keys for gemeente amsterdam APIs, the first step is to obtain a key using the online form.
When accessing the APIs, every http request needs
to use an X-Api-Key request header that has the
value of the api key that has been obtained by filling out the
form mentioned above.
Geotools that are using the WFS endpoints are not always
able to use an http request header.
So, it is also possible to use
a query parameter x-api-key with the api key.
However, if possible, use an http request header,
because that is less error-prone.
Example using curl for a REST API call with the API key:
curl https://api.data.amsterdam.nl/v1/gebieden/wijken/ -H "X-Api-Key: very...long...token".
NB. The API Key is only being used to register the useage of our APIs. It does not provide any authentication or authorizations to the APIs.
