     The API provides one endpoint that accepts POST requests for retrieving population
     density information in the specified area.
 
+    # Authorization and Authentication
+    
+    CAMARA guidelines defines a set of authorization flows which can grant API clients access
+    to the API functionality, as outlined in the document [CAMARA-API-access-and-user-consent.md](https://github.com/camaraproject/IdentityAndConsentManagement/blob/main/documentation/CAMARA-API-access-and-user-consent.md).
+    Which specific authorization flows are to be used will be determined during
+    onboarding process, happening between the API Client and the Telco Operator
+    exposing the API, taking into account the declared purpose for accessing the API,
+    while also being subject to the prevailing legal framework dictated by local legislation.
+    It is important to remark that in cases where personal user data is processed by the API,
+    and users can exercise their rights through mechanisms such as opt-in and/or opt-out,
+    the use of 3-legged access tokens becomes mandatory. This measure ensures that the API remains
+    in strict compliance with user privacy preferences and regulatory obligations, upholding the 
+    principles of transparency and user-centric data control.
+
+    Population Density Data API ensures the usage of anonymized information and do not treat
+    personal data neither as input nor output. 
+    Therefore, the access to Population Density Data API is defined as 
+    Client Credentials - 2-legged as described in [CAMARA-API-access-and-user-consent.md - Client Credentials](https://github.com/camaraproject/IdentityAndConsentManagement/blob/main/documentation/CAMARA-API-access-and-user-consent.md#client-credentials)
