Query Zoho CRM Data from Node.js
The API Server exposes Web services that allow connectivity to your data. Use the OData endpoint of the CData API Server to execute CRUD queries to Zoho CRM data from Node.js.
The CData API Server, when paired with the ADO.NET Provider for Zoho CRM, exposes Zoho CRM data (or data from any of 200+ other ADO.NET Providers) as an OData endpoint, which can be queried from Node.js using simple HTTP requests. This article shows how to use the API Server to request JSON-formatted Zoho CRM data in Node.js.
Set Up the API Server
Follow the steps below to begin producing secure Zoho CRM OData services:
Deploy
The API Server runs on your own server. On Windows, you can deploy using the stand-alone server or IIS. On a Java servlet container, drop in the API Server WAR file. See the help documentation for more information and how-tos.
The API Server is also easy to deploy on Microsoft Azure, Amazon EC2, and Heroku.
Connect to Zoho CRM
After you deploy the API Server and the ADO.NET Provider for Zoho CRM, provide authentication values and other connection properties needed to connect to Zoho CRM by clicking Settings -> Connections and adding a new connection in the API Server administration console.
The connector is already registered with Zoho CRM as an OAuth application. As such, OAuth Credentials are embedded by default. If you would prefer to use your own custom OAuth app, see the Custom Credentials section in the Help documentation.
You can then choose the Zoho CRM entities you want to allow the API Server access to by clicking Settings -> Resources.
Authorize API Server Users
After determining the OData services you want to produce, authorize users by clicking Settings -> Users. The API Server uses authtoken-based authentication and supports the major authentication schemes. Access can also be restricted based on IP address; all IP addresses except the local machine are restricted by default. You can authenticate as well as encrypt connections with SSL.
Consume Zoho CRM OData Feeds from Node.js
OData feeds are easy to work with in Node.js. You can use the HTTP client in Node.js to request JSON-formatted data from the API Server's OData endpoint. After making the request, you can construct the body of the response and call the JSON.parse() function to parse it into records.
The code below will make an authenticated request for Accounts data. The example URL below applies a simple filter that searches for records with a value of Data/Telecom OEM in the Industry column.
var http = require('http');
http.get({
protocol: "http:",
hostname: "MyServer.com",
port: MyPort,
path: "/api.rsc/Accounts?$filter=" + encodeURIComponent("Industry eq 'Data/Telecom OEM'"),
auth: 'MyUser:MyAuthtoken'
},
function(res) {
var body = '';
res.on('data', function(chunk) {
body += chunk;
});
res.on('end', function() {
console.log(body);
var jsonData = JSON.parse(body);
});
}).on('error', function(e) {
console.log("Error: ", e);
});
