Authenticating requests

To authenticate requests, include a X-SecureCode header with the value "9SRLYBCALURPE2B".

All authenticated endpoints are marked with a requires authentication badge in the documentation below.

And header X-ClientId 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-ClientId1177
X-SecureCode9SRLYBCALURPE2B
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 20 218 1024 if you want to increase the number of requests.
