Quality APIs only

How can you tell whether API's are trustworthy, available and work the way they promise, with us this isn't an issue. When you integrate an API into your own applications, it’s important that an API lives up to your – and your organization’s – standards. That's why our developers make sure an API delivers real value and works the way it should before making it available in the KPN Developer Portal.

Our portal enables you to use APIs from suppliers that we trust and have proven to live up to KPN quality and safety standards. We also offer our own KPN APIs. In both cases, an API only gets a place in our portal if we believe it is worth your while.

Test for free

  1. Check out APIs docs and tutorials

  2. Create a free account

  3. Test APIs for free

  4. Upgrade your account

  5. Take APIs into production 

Did you see an API that could help you with your use case? Register for a free account, so you can start testing in our sandbox. Testing APIs is completely free. There are limits per API, but the standard amount of free requests should be enough to test an API thoroughly. If you need more requests, send us a message and we’ll arrange it for you.

You get your own set of API keys (client ID and secret) for accessing all the APIs in our portal. Our documentation and tutorials should help you get started with an API. The sample data in Swagger files allow you to see exactly how an API would function in your own application.

Taking products into production

You want to use a developer product in production? Then you need to upgrade your account. There are two options to upgrade, for one you need your company's unique KPN Registration Number (KRN number), for the other option we will verify your personal identity by comparing it with the name on your personal bank account (an 'iDIN check'). We will only use your personal bank account number once to check your identity. We use the bank account of your company in the case that we will send invoices, of course.

From there on, you are a verified KPN Developer Portal member and start paying per use (unless it's a free service of course). How much and if you pay, varies per product (see product pages for pricing details per product). Testing will always continue to be free after you upgrade.
