Introduction

Welcome to the official Postcode Service API documentation!

The most up to date postcode service for the Netherlands and Belgium. Our clients have saved yearly over 1 million euro in RMA (Return Material Authorization).

Questions?

You can contact our experts via support@postcodeservice.com or call our office in Amsterdam +31 20 36 94 049.

Plugins & extensions

There is a ready-to-use Magento 2 extension on github: tig-nl/postcode-magento2. For installation support you can contact our experts support@postcodeservice.com or call our office in Amsterdam +31 20 36 94 049.

Authenticating requests

Authenticate requests to this API's endpoints by sending a X-Secure_Code header with the value "{your-token}".

And header X-Client_Id with {YOUR_CLIENT_ID}. You can retrieve your credentials by visiting our https://postcodeservice.com.

Try it yourself, right now!

You can use these test credentials. Keep in mind there is a daily maximum.

X-Client_Id1177
X-Secure_Code9SRLYBCALURPE2B
X-Domain (optional)https://postcodeservice.com/

Rate limited

If a response code 429 (429 Too Many Requests is visible in the browser) is returned, you have reached the maximum number of requests per second specified in your contract. The default is 10 requests/seconds. As soon as the number of requests falls below the maximum number again (standard <10 requests/s) you will receive the usual responses again. You can contact your account manager on telephone number +31 20 36 94 049 if you want to increase the number of requests.
