Square-connection NPM

Square Connection

A simple way to connect to the Square Connect API.

What this Is

SquareConnection is a promise-based module built with Axios that offers a quick and easy way to start hitting the Square Connect API.

Getting Started

npm install --save square-connection

Simple Usage

Import the module:

import SquareConnection from 'square-connection';

Use the module:

const square = new SquareConnection('YOUR_ACCESS_TOKEN');
const request = square.get('/customers');

request.then((result) => {
  console.log(result); // logs out an Axios result object if the API call succeded
});

request.catch((error) => {
  console.log(error); // logs out an Axios error object if the API call didn't succed
});

Constructor

The constructor takes in three parameters: the accessToken (required), the connect version (v2), and the connect url.

Param	Type	Default	Description
accessToken	String	`''` (Required)	The access token from your Square Application
version	String	`'v2'`	The Square Connect API version (v2 is the only supported version, but you're welcome to try v1)
connectUrl	String	`'https://connect.squareup.com/'`	The url through which to connect to the Square Connect API (should probably be left alone)

API

Currently, you there are no specific methods in this module's API, though they are set to come soon. As for now, it serves as only a quick way of doing GET, POST, PUT, and DELETE requests to Square. You define the route and the body.

Method	Parameters	Description
get	String path, Object query	The path defines the resource being requested. The query should be a single-level JS object with key-value pairs which can/will be encoded via encodeURIComponent
post	String path, Object body	The path defines the resource being posted to. The body is a simple JS object to be accepted by Square's API
put	String path, Object body	The path defines the resource being put to. The body is a simple JS object to be accepted by Square's API
delete	String path, Object query	The path defines the resource being deleted. The query should be a single-level JS object with key-value pairs which can/will be encoded via encodeURIComponent
