Important

SumUp POS Pro is currently being gradually deprecated and will no longer be available by the end of 2026. As a result, we are no longer supporting new integrations with POS Pro or opening new partnership opportunities based on this product.

For any future integration requests, please get back in touch with us from Q2 2027 onwards at [email protected].

🇫🇷 l’application SumUp POS Pro ne sera plus disponible à compter de la fin de l’année 2026. En conséquence, nous n’acceptons plus de nouvelles demandes d’intégration et n’ouvrons plus de nouvelles opportunités de partenariat liées à ce produit.

Pour toute future demande d’intégration, nous vous invitons à nous recontacter à partir du deuxième trimestre 2027 à l’adresse suivante : [email protected].

You’re probably looking to access SumUp POS Pro API and to develop an integration with our ecosystem. You’re a company with a technological solution or a merchant who wants a specific solution for your own store.

Either way, you’re in the right place.

SumUp POS Pro provides an API to connect and extend SumUp POS Pro system with:

• endpoints to retrieve or to post data regarding objects such as orders, pricebooks
• webhooks to be automatically notified when changes occur on subscribed events

API versions

This document is about SumUp POS Pro API V3. if you are looking for information about the previous version (Tiller API V2) please go to https://tiller-api.readme.io/.

Unless you have an existing integration using Tiller API V2, it is highly recommended to start developing a new integration with SumUp POS Pro API V3.

Environments

SumUp POS Pro provides two environments:

• SANDBOX: to develop and test your integration
• PRODUCTION: the real-life store environment

Environments are disconnected:

Your SANDBOX store behaves independently from the PRODUCTION store.
SANDBOX allows you to test your integration without risk of interfering with PRODUCTION data.

The mobile application running on iOS iPad is able to switch from SANDBOX to PRODUCTION at will. Users declared in the SANDBOX and PRODUCTION environments are also independent and one must reconnect on the iPad to switch from one environment to the other.
