# Zettle {% hint style="info" %} 💪 **Difficulty:** very easy ⏳ **Time to complete**: approx. 2 minutes {% endhint %} ## 💬 Description Zettle is a payment and POS solution. With Less, you can extract Transaction, Product, Purchase, and Discount information. ## 🤑 Use Case There are a lot of options. Start by getting some transparency on where and when you making money. When you're ready, integrate it with your Marketing data to understand if there’s a correlation between marketing efforts and revenue. Or maybe an Internal Database (like MySQL) to get a better customer understanding. With your finance system for understanding profitability. As we said, a lot of options. ## 🛠️ Setup Zettle is an OAuth Connector which means that all you have to do is log in with your Zettle account and select the tables your want to extract. You’ll be redirected from Less to Zettle to authenticate, but once that’s done, we’ll bring you back to Less. From here, all you need to do is select the tables you want to extract. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
