Test our API's and start creating your application
Developing your application requires an API key. To get your key, you simply register by filling out the request form. Creating an application starts with selecting the APIs that you want to use. We will contact you and send the API key(s) by email as soon as possible. With this key you’re ready to start developing your application. Dependent on which APIs you would like to use, you need separate keys for each API. For most paid APIs you will receive free credits to test the services.
If you are already a PostNL Parcels customer with PostNL customer number, it is highly recommended to request the API key via MijnPostNL. In this way, your customer data is directly linked to your personal API credentials.
Note: This only applies to apis from the categories Send & Track, Delivery Options and Checkout APIs.
If you are not a PostNL customer yet or you (also) want to explore our Addresses and Customer Overview APIs please fill in the form below.
