Fast and reliable text messaging with KPN's SMS API

Inform users with SMS updates, confirmations and notifications

Integrate fast and reliable SMS messaging into your application with the SMS API from KPN. Send updates, confirmations, reminders and other notifications to your customers and employees directly from your application. Reach users globally in any language. You can easily integrate it into your own software and use SMS to send timely notifications and to boost conversion. You pay per use only, so no investment is needed.

How it works

Through the SMS API you are connected to KPN’s Short Message Peer-to-Peer (SMPP) protocol. In this way you don't need to develop and support a protocol yourself. Send SMSes by sending calls to the API. In the API call you can insert your content and set the right settings for your purpose. Your SMS messages are always delivered quickly and reliably via KPN's network. Want to see how it works?
