API reference on SwaggerHub API reference on Postman


The Health Data Aggregator API links data from digital health wearables, devices and apps. This allows you to personalize your fitness, health and lifestyle services to individual users. Also, you can build your own intervention and prevention campaigns based on health and physical activity data. Examples of such data are steps, calorie consumption, weight, heart rate, sleep quality, blood pressure and glucose level.

Conceptual model

Conceptual model



A tile represents a specific bit of data related to fitness, health or lifestyle. For instance, the activity tile represents a daily activity summary such as walking, running etc. Or data such calculated BMI, sleep log and body temperature.

Getting started


OAuth 2.0

For accessing and/or manipulating the resources, the client application (your application) needs to be granted permission to do so. The OAuth 2.0 standard defines a protocol that allows such third party authorization through the use of access tokens. Access tokens are central in the protocol. These tokens, in the form of strings, are delivered by an authorization server (our authentication server) and they enable the client application to securely access protected data on behalf of the resource owner (the end user).

We use Client Credentials Grant. This means the application makes the request to the authentication service by sending authorization credentials. The service responds with an access token among other useful information.

Get access token

Copy your app's credentials and replace APP_CONSUMER_KEY and APP_CONSUMER_SECRET with the copied values, then execute the below cURL command to receive an access token.

curl -X POST  'https://api-prd.kpn.com/oauth/client_credential/accesstoken?grant_type=client_credentials'  -H 'content-type: application/x-www-form-urlencoded'  -d 'client_id=APP_CONSUMER_KEY&client_secret=APP_CONSUMER_SECRET'

Note: If you are using cURL for Windows then please use the below command.

curl -X POST "https://api-prd.kpn.com/oauth/client_credential/accesstoken?grant_type=client_credentials" -H "content-type: application/x-www-form-urlencoded" -d "client_id=APP_CONSUMER_KEY&client_secret=APP_CONSUMER_SECRET"

The authorization service returns a JSON message that contains the access token field.
