Authentication
Authentication is the process of proving your identity to the system. The KPN Developer Portal uses the OAuth 2.0 Client Credentials Grant type: Client ID and Client secret.
To use the KPN APIs, you must obtain an access token (also called bearer token) by invoking our Authorization API using a POST method and sending the client credentials in the request.

Authentication workflow

Where can I find my client credentials
Login into the My Developer Portal.
- Sandbox: Click on Sandbox to see your
Client IDandClient secretfor all APIs in the Sandbox. Use these credentials for testing. - Project: Click on a project in Projects to see your
Client IDandClient secretfor all APIs in that project. Use these credentials for your production applications.
Use them for authorization in SwaggerHub or when you send an API request to the KPN Developer Portal, for example with Postman or in a cURL request. You will receive an access token in the JSON message body of the response.
For example: "access_token": "haf2SDl07E9N7RluNQ4kJ1TkGgso".
Authenticating using cURL
Execute the cURL command to receive an access token. Replace APP_CLIENT_ID and APP_CLIENT_SECRET with your credentials (Client ID and Client secret).
cURL for Linux and MacOS
Code copied 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_CLIENT_ID&client_secret=APP_CLIENT_SECRET'cURL for Windows
If you are using cURL for Windows, please use the command below instead.
Code copied 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_CLIENT_ID&client_secret=APP_CLIENT_SECRET"Response
The authentication service returns a JSON message that contains the access_token field.

- Click on the
Authorizebutton on the right. - In the form, fill in
client_idandclient_secret, using your KPN Developer Portal credentials (Client IDandClient secret). - Click
Authorize.
Note: Even if the button says Authorize, it's really the authentication process.
Authenticating using Postman
When using Postman, you will have to import the Swagger file into a Postman collection as follows:
- Open the API reference on SwaggerHub.
- On the top right, click
Export, clickDownload APIand click 'YAML Unresolved'. - In Postman from the menu click
Fileand clickImport... Choose the YAML file you downloaded in the previous step. A new collection will be added. - Select

- Edit the environment variables
client_idandclient_secret, using your credentials (Client IDandClient secret). - Check the response code and message.
- Press the
Sendbutton to get an access token.
