API access ✨
You can use API access to KPN Things for instance to automate some actions you normally do manually through the KPN Things Portal.
Early access feature! API access to KPN Things is currently in beta! We try to notify users in advance about breaking changes, but we cannot guarantee continuity of this service just yet.

How Things API access works

The API Key

To access the KPN Things APIs you need an API Key. And these API Keys are managed by GRIP, the identify management platform of KPN. Your user account used to access the KPN Things Portal is also managed by GRIP. Learn more about the account you use to access KPN Things.
In GRIP there are API Keys. These are separate entities in a tenant (a customer environment). That means an API key is not user bound, but it is rather a separate entity.
API Keys are (like Users) part of a GRIP Tenant and represent an entity that can log into KPN applications.

The access token

Each time you want to access the KPN Things APIs, you need to request an access token from the GRIP API using your API Key. This access token you get is valid for one hour, and can be used as a bearer token to access KPN Things APIs directly.
That means, for each API call you to to KPN Things. you need to add the following Authorization header:
1
Authorization: Bearer {accessToken}
Copied!
There is no refresh token. To regain access after the validity of your access token has expired, just request another access token through the GRIP API.
You can find more information about the access method we employ here on the Grip Knowledge Base website, linked below. The method is called Machine authentication.

The required information to request access token

You will need the following four values to be able to request an access token from GRIP:
Value
Description
Tenant ID
The unique identifier of your GRIP environment. Follow step 1 in the getting started to find it in the Things Portal.
Application ID
The ID of the service you want to access, being KPN Things. Used as audience in your client credentials request.
For KPN Things it is this: 4dc82561-f65f-523g-dek9-6c79ec314f02
Client ID
The API Key's ID you get from step 2 of the getting started.
Client Secret
The API Key's Secret key you get from step 2 of the getting started.

Getting started

1. Find your Tenant ID in the Things Portal

In the KPN Things Portal, visit the Customer detail page by clicking on your name in the top right and then clicking "Customer Details" in the overflow menu. On the following page you will find your GRIP Tenant ID.

2. Create your API Key and API Key's Secret in GRIP

It is best practice to create individual API Keys for each instance that will access the KPN Things APIs.
Log into the GRIP Portal as administrator.
  • If you have a KPN Developer account, you will be administrator in the GRIP Portal.
  • If you have a MijnKPN Zakelijk account, you should ask your local administrator for access.

To be able to create API Keys, you need to be an administrator in the GRIP Portal.
Then, open the Admin panel using the role drop down (#1 in the screenshot), click on Identity in the side menu (#2 in the screenshot) and click on API keys (#3 in the screenshot). This brings you to the API Key management page. Now, click Add to add a new API Key (#4 in the screenshot).

2.2. Create new API Key

In the following pop-up, give your new API Key a Display name and a Description. Then click Add to create your new API Key.

2.3. Give new API Key access to KPN Things

You need to give your newly created API Key access to the KPN Things Portal service before you can use it. For this, click on Services and roles (#1 in the screenshot), and click on Add a service (#2 in the screenshot).
A modal will open. Click on the checkbox next to KPN Things Portal (#1 in the screenshot) and hit Add (#2 in the screenshot).
Then, click Save to finally give your API Key access to KPN Things.

2.4. Fetch credentials of new API Key

Now, when you click back on General information, you will see the ID and Secret key of your new API Key.

Perform API call in sub-customer environment

💎 Add-on feature This feature is only available if you have the add-on feature Customer Management.
If you have Customer Management in your account, you can manage Things accounts for your own customers. These customers of you, let's call them sub-customers, have their own customer account in KPN Things. But you have access rights with your API Key to perform actions in their account.

The principle

To perform an API call in a sub-customer environment, there are two requirements:
  1. 1.
    You should have requested the access rights to the individual sub-customer environment
  2. 2.
    For all API calls you perform, you should add the following HTTP header:
1
x-client-id: {{customerID}}
Copied!

Step 1: Request access rights

This only has to be one once per API Key per sub-customer.
  1. 1.
    Find the Customer ID from the sub-customer you want to perform an action on. You can use the All Customers page to search in your Customers and then open the Customer details page of the concerning Customer to find its Customer ID.
  2. 3.
    Perform the following API call:
get
https://api.kpnthings.com
/api/v1/lifecycle/clients/:clientId/context-switch
Request access rights to a sub-customer

Step 2: Perform API call in sub-customer environment

Now you have access rights to the sub-customer environment with your API key. Now you can perform any API call you have the rights for in the sub-customer environment by simply adding the x-client-id header to the API call when you execute it.
