API keys are unique codes that identify you or your application each time you make a call to one of our API’s.
To make API requests you will need an API Key. Please register in order to receive credentials.
In order to receive real (non-dummy) data output you will need a production account. After registration you will be given personalized login credentials and receive further instructions to activate your product account.
Do you already have a contract to access API’s from either Cendris or Data Solutions by PostNL (both wholly owned by PostNL)? Please contact your Account Manager.
IBAN is a way of showing your existing bank account details in an internationally recognised and standardised format.
