Square’s POS API is perfect for businesses that want to build upon the out-of-the-box capabilities of our Square Point of Sale app. For example, custom furniture stores might need complex order forms for customised item specs. Museums and events sometimes have custom ticketing requirements and payments. Professional services might need custom order management workflows such as assessment and delivery dates. In all these cases, developers can create a customised POS app that integrate easily with Square’s POS API to take care of the payment flow process. Táve and Checkfront, for example, are all apps that have integrated with our POS API to take in-person payments.

Our point-of-sale API is fully Encrypted, our fees are competitive, and our sellers get paid fast.
Why we made our POS API
We started our payments company so anyone anywhere could take credit and debit card payments. Creating our POS integration API is a continuation of that mission. We’ve built a really solid payments infrastructure and want to allow people to build on top of it. Our POS API is a great way to support businesses that have more complicated POS needs than what we’re able to provide with our standard offering.
How does the point-of-sale (POS) API work?
Our POS integration API uses an app switch, meaning the app switches between your custom POS and Square’s Point of Sale app to process a payment. With just a few lines of code, you’re ready to initiate a transaction from your POS. Once initiated, it automatically switches you into the Point of Sale app. There you can tap or dip cards, or tap devices such as Apple and Android Pay. After the payment flow, the app switches back to your custom POS. It’s simple and easy.
What POS features can I expect?
- Quick, easy API integration
- Cutting-edge hardware that accepts contactless cards, devices with Apple Pay and Google Pay as well as chip cards
- End-to-end payments encryption
- Quick deposits: merchants see payments in their bank accounts in one to two business days
