PepperHQ Developer

The PepperHQ Developer Hub

Hand crafted, customised and bespoke mobile experiences to suit your brand and needs.



This section of the PepperHQ Developer Documentation provides both an overview and a detailed guide for developers who are planning to implement an integration between the PepperHQ technology and a 3rd Party Point-of-Sale (PoS) system.

This document assumes the reader has an understanding of the PepperHQ offering. For a demo of the Pepper product, please contact your Pepper representative. If you don’t know who your Pepper representative is, please get in touch via [email protected].

For detailed descriptions of how to integrate in the supported scenarios, please see:

Integration Nodes

In order to implement the end-user scenarios described in the guides, there are several possible points of integration between PepperHQ and the 3rd Party PoS.

The points of integration that are relevant for a specific integration are determined by the needs of the Merchant as well as the constraints of the 3rd Party PoS.

The four possible points of integration are:

  • Pepper Application - running on the end-user’s smartphone.
  • Pepper Platform - exposed as a REST API (at
  • PoS API - exposed over the Internet as an API for consumption by the Pepper Platform.
  • PoS Application - running locally in the Merchant’s venues.

Pepper Platform API

The features of the PepperHQ Platform are made available to developers via a RESTful API. Please see the Platform REST API section of this site for a complete description of the API.

3rd Party PoS Connector

In cases where the PoS API does not conform to the requirements of the Pepper Platform (as described in these guides) a Connector must be developed that bridges the gaps.

The options that are available to create a Connector are varied but are ultimately integrated into the Pepper platform as a Node.js package delivered as an npm private package.

Please see the Service Facade document for a description of the conventions and constraints that the Pepper Platform expects when consuming a 3rd Party PoS.

The pattern for the method calls' arguments for a 3rd Party PoS Connector are as follows:

methodName(identifier, data, options, callback)
  • identifier is an optional string that is only necessary when the method acts upon an existing resource (e.g. an existing Order)
  • data is an optional object that contains the key data required for processing (e.g. an Order basket).
  • options is an optional object that contains contextual information that the PoS may need for processing, such as access keys for the PoS's own API.
  • callback is a function that should be called when the request has been processed. The function takes error and result objects as parameters.
