Query PayPal Data as a SQL Server Database in Node.js

You can use CData Connect Cloud to query PayPal data through a SQL Server interface. Follow the procedure below to create a virtual database for PayPal in Connect Cloud and start querying using Node.js.

CData Connect Cloud provides a pure MySQL, cloud-to-cloud interface for PayPal, allowing you to easily query live PayPal data in Node.js — without replicating the data to a natively supported database. As you query data in Node.js, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc) directly to PayPal, leveraging server-side processing to quickly return PayPal data.

Configure PayPal Connectivity for NodeJS

Connectivity to PayPal from NodeJS is made possible through CData Connect Cloud. To work with PayPal data from NodeJS, we start by creating and configuring a PayPal connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "PayPal" from the Add Connection panel
3. Enter the necessary authentication properties to connect to PayPal.

   The provider surfaces tables from two PayPal APIs. The APIs use different authentication methods.

   • The REST API uses the OAuth standard. To authenticate to the REST API, you will need to set the OAuthClientId, OAuthClientSecret, and CallbackURL properties.
   • The Classic API requires Signature API credentials. To authenticate to the Classic API, you will need to obtain an API username, password, and signature.

   See the "Getting Started" chapter of the help documentation for a guide to obtaining the necessary API credentials.

   To select the API you want to work with, you can set the Schema property to REST or SOAP. By default the SOAP schema will be used.

   For testing purposes you can set UseSandbox to true and use sandbox credentials.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add PayPal Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured, you are ready to connect to PayPal data from Node.js.

Query PayPal from Node.js

The following example shows how to define a connection and execute queries to PayPal with the SQL Server module. You will need the following information:

• server: tds.cdata.com
• port: 14333
• user: a Connect Cloud user (e.g. user@mydomain.com)
• password: the PAT for the above user
• database: The connection you configured for PayPal (PayPal1)

Connect to PayPal data and start executing queries with the code below:

var sql = require('mssql')
var config = {
	server: 'tds.cdata.com',
	port: 14333, 
	user: 'user@mydomain.com', //update me
	password: 'CONNECT_USER_PAT', //update me	
	options: {
		encrypt: true,
		database: 'PayPal1'
	}
}

sql.connect(config, err => { 
    if(err){
        throw err ;
    }
    new sql.Request().query('SELECT * FROM Transactions', (err, result) => {
        console.dir(result)
    })
        
});

sql.on('error', err => {
    console.log("SQL Error: " ,err);
})
