## NOTICE: The Square Connect Node.js SDK is retired and replaced by [square/square-nodejs-sdk]

This Connect Node.js SDK is retired as of 2021-04-21 and will not receive any updates. To continue receiving API and SDK improvements, bug fixes, and security patches, please follow the instructions below to migrate to the new [Square Node.js SDK].



The old Connect SDK documentation is available under the [/docs] folder.

## Migrate to the Square Node.js SDK



Follow the instructions below to migrate your apps from this retired Connect Node.js SDK to the new [Square Node.js SDK]. You will need to install the new SDK and update your application code.



### Install the Square Node.js SDK



```sh

$ npm install square

```



### Update your application code

Make the following changes to migrate your application code to the new Square SDK:



1. Change all instances that import the `square-connect` library to import the `square` library.

1. Update the instantiation and initialization of the API client to follow the method described below.

1. Replace `square-connect` models with the new `square` equivalents with camel case parameter names.

1. Update code for calling Square APIs and accessing response data to follow the method described below.



**Note:** The new SDK supports TypeScript. It exports type files that you can use to type-check the SDK usage in TypeScript codebases.



### Client instantiation and initialization

Use the following examples to compare client instantiation and initialization in the retired SDK versus the new SDK.



#### Retired Connect SDK

This is how you import the `square-connect` library, and instantiate and initialize the API client.

```javascript

var SquareConnect = require('square-connect');

var defaultClient = SquareConnect.ApiClient.instance;



// To access sandbox resources, set the basePath to the sandbox URL

//defaultClient.basePath = 'https://connect.squareupsandbox.com';



// Configure OAuth2 access token for authorization: oauth2

var oauth2 = defaultClient.authentications['oauth2'];

oauth2.accessToken = process.env.SQUARE_ACCESS_TOKEN;

```



#### New Square SDK

This is how you can do the same thing with the new `square` library. You can import using the ES module or CommonJS module syntax, but you should not mix the two import styles in the same codebase.



**Option 1: ES module import example** (recommended)

```javascript

import {  ApiError, Client, Environment  } from 'square'



const client = new Client({

  timeout:3000,

  environment: Environment.Production, // `Environment.Sandbox` to access sandbox resources

  accessToken: process.env.SQUARE_ACCESS_TOKEN,

})

```

**Option 2: CommonJS module import example**  

```javascript

const {  ApiError, Client, Environment  } = require('square')



const client = new Client({

  timeout:3000,

  environment: Environment.Production, // `Environment.Sandbox` to access sandbox resources

  accessToken: process.env.SQUARE_ACCESS_TOKEN,

})

```



### Example code migration

As a specific example, consider the code for creating a customer in the sandbox environment.



#### Retired Connect SDK

The following example uses the `square-connect` library to create a customer.

```javascript

var SquareConnect = require('square-connect');



// Instantiate and initialize the API client

var defaultClient = SquareConnect.ApiClient.instance;

defaultClient.basePath = 'https://connect.squareupsandbox.com';

var oauth2 = defaultClient.authentications['oauth2'];

oauth2.accessToken = process.env.SQUARE_ACCESS_TOKEN;



// Unique key to ensure this operation runs only once if you need to retry

var idempotencyKey = "unique_key";



var requestBody = SquareConnect.CreateCustomerRequest.constructFromObject({

  idempotency_key: idempotencyKey, // Parameters use snake case

  given_name: "Amelia",

  family_name: "Earhart",

  email_address: "[email protected]"

});



// Get an instance of the Square API you want call

var customersApi = new SquareConnect.CustomersApi();



// Call the API

customersApi.createCustomer(requestBody).then(function(result) {

  console.log('API called successfully. Returned data: ' + JSON.stringify(result, 0, 1));

}, function(error) {

  console.error(error);

});

```



#### New Square SDK

Now consider equivalent code that uses the new `square` library. Note the following:

   * Calls to a Square API must be wrapped in an asynchronous function.

   * Parameter names must be changed from snake case to camel case, for example from `location_id` to `locationId`.

   * Square API calls return an ApiResponse or throw an ApiError. Use a try/catch statement to check whether the response succeeded or failed. Both objects contain properties that describe the request (`headers` and `request`) and the response (`statusCode`, `body`, and `result`). The response payload is returned as text in the `body` property or as a dictionary in the `result` property.



```javascript

import { ApiError, Client, Environment } from 'square'



// Instantiate and initialize the API client

const client = new Client({

  environment: Environment.Sandbox,

  accessToken: process.env.SQUARE_ACCESS_TOKEN,

})



// Get an instance of the Square API you want call

const { customersApi }  = client



// Unique key to ensure this operation runs only once if you need to retry

let idempotencyKey = "unique_key"



// Call the API from within an async function

const createCustomer = async () => {

  let requestBody = {

    idempotencyKey: idempotencyKey,  // Parameters use camel case

    givenName: "Amelia",  

    familyName: "Earhart",

    emailAddress: "[email protected]"

  }



  // Use a try/catch statement to check if the response succeeded or failed

  try {

    let { result } = await customersApi.createCustomer(requestBody)     

    console.log('API called successfully. Returned data: 'result)

  } catch (error) {

    if (error instanceof ApiError) {

      console.log("Errors: ", error.errors)

    } else {

      console.log("Unexpected Error: ", error)

    }

  }

}

createCustomer()

```



That's it!
