At Clover, we design and build low-cost and highly functional Android-based point-of-sale (POS) systems for small or medium-sized businesses (SMB). Clover merchants use our suite of apps for different business functions.

Clover is an open platform allowing third-party developers to build apps and integrate external POS systems with Clover devices.

Learn to use the Android Payments API

Payment interfaces for semi-integration

Depending on the combination of merchant- and customer-facing devices you require, Clover offers different payment interfaces.

This java-based API has all the Clover features needed for your app to make a sale, issue a refund, and perform other payment functions.

Use this API to build a point-of-sale directly on a Clover device.

Enables external POS systems to access the same payment functions as PaymentConnector
— plus additional features.

SDKs are available for these platforms:
Android | iOS | Javascript | .NET

Quickly build a bridge between your point-of-sale (POS) system and a Clover Flex or Clover Mini.

  • Any POS application capable of making HTTP requests can use REST Pay to take card-present payments.
  • A merchant can take any type of standard card-present payments after your POS app is integrated with REST Pay.
  • Developers familiar with the Ecommerce API can quickly add an in-person payment option to their app.

Apps running on Clover devices use this intent-based API for executing payment transaction requests.

The Android intents are built using 'Intent Builders' and support payment operations including payments, preauthorizations, and payment reversals (void/refund).

NOTE: The Android Payments API is intended to eventually replace 'PaymentConnector', as it provides more capabilities and support for additional configurations.
