This SDK is archived. You can continue to use it, but no new features or support requests will be accepted. For the new version, refer to https://www.zoho.com/crm/developer/docs/sdk/server-side/nodejs-sdk.html
Node SDK is a wrapper for Zoho CRM APIs. Hence invoking a Zoho CRM API from your Node application is just a function call which provide the most appropriate response.
This SDK supports both single user as well as multi user authentication.
Since Zoho CRM APIs are authenticated with OAuth2 standards, you should register your client app with Zoho. To register your app:
- Visit this page https://accounts.zoho.com/developerconsole.
- Click on “Add Client ID”.
- Enter Client Name, Client Domain and Redirect URI.
- Select the Client Type as "Web based".
- Click “Create”.
- Your Client app would have been created and displayed by now.
- The newly registered app's Client ID and Client Secret can be found by clicking Options → Edit.
(Options is the three dot icon at the right corner).
Node JS SDK will be installed and a package named 'zcrmsdk' will be created in the installation directory.
npm install zcrmsdk
Once installed it can be used in the code as below,
var ZCRMRestClient = require('zcrmsdk')
Your OAuth Client details should be given to the SDK as a property file. In the SDK, you need to configure a file named oauth_configuration.properties. Please place the respective values in that file. You can place it under resources/ package from where the SDK is used.
zcrmsdk will try reading file from 'resources/oauth_configuration.properties'
Please fill the values for the following keys alone. Based on your domain(EU,CN), please change the value of crm.iamurl. Default value set as US domain.
[zoho]
crm.iamurl=
crm.clientid=
crm.clientsecret=
crm.redirecturl=
crm.clientid, crm.clientsecret and crm.redirecturl are your OAuth client’s configurations that you get after registering your Zoho client. crm.iamurl is the accounts URL. It may be accounts.zoho.com or accounts.zoho.eu. If the crm.iamurl is not specified, by default the URL will be accounts.zoho.com.
In configuration.properties file:
[crm]
api.url=
api.user_identifier=
api.tokenmanagement=
[mysql]
username=
password=
api.url is the URL used to call APIs. By default, the URL is www.zohoapis.com. api.user_identifier will be empty by default. For single user authentication, this key can be filled with the respective email id, so that all calls happens by using this user's authentication. api.tokenmanagement is given as a measure to manage and maintain tokens. If tokenmanagement is not provided, then sdk's default implementation(mysql) will be followed. username and password can be given here if you already have one created for your MySQL. The above keys specified in configuration.properties file are all optional.
user_identifier can be set in two ways . 1.Mentioning it in api.user_identifier in configuration.properties file 2.Can be set via code using set setUserIdentifier.
If user_identifier is not set via both the ways then default value 'zcrm_default_user' will be set by the sdk itself .
To use the default token storage provided by the SDK, the following are to be done:
Mysql should be running in default port in localhost.
Database with name zohooauth should be created and a table with below configurations should be present in the database. Table, named "oauthtokens", should have the columns "useridentifier" (varchar) "accesstoken" (varchar), "refreshtoken" (varchar) and "expirytime" (bigint).
Once the configuration is set, storage and retrieval of tokens will be handled by the SDK. If the user wants to utilize their own mechanism, they can mention it in configuration.properties by providing the respective module in api.tokenmanagement.
This module should contain the below methods, saveOAuthTokens(token_obj) updateOAuthTokens(token_obj) Irrespective of response, the next execution happens. So care should be taken by the user in handling their module. getOAuthTokens() The expected response for this method : JSON array containing json response with expirytime, refreshtoken and accesstoken fields.
For self client apps, the self authorized grant token should be generated from the Zoho Developer Console (https://accounts.zoho.com/developerconsole)
- Visit https://accounts.zoho.com/developerconsole
- Click Options → Self Client of the client for which you wish to authorize.
- Enter one or more (comma separated) valid Zoho CRM scopes that you wish to authorize in the “Scope” field and choose the time of expiry. Provide “aaaserver.profile.READ” scope along with Zoho CRM scopes.
- Copy the grant token for backup.
- Generate refresh_token from grant token by making a POST request with the URL below https://accounts.zoho.com/oauth/v2/token?code={grant_token}&redirect_uri={redirect_uri}&client_id={client_id}&client_secret={client_secret}&grant_type=authorization_code
- Copy the refresh token for backup.
Please note that the generated grant token is valid only for the stipulated time you chose while generating it. Hence, the access and refresh tokens should be generated within that time.
Each time server is restarted, this function has to be called and both the configuration files should be populated with proper values before calling this function, else exception will be thrown.
All functions return promises in zcrm node sdk.
Below snippet has to be called before starting the app
var ZCRMRestClient = require('zcrmsdk');
ZCRMRestClient.initialize().then(function(){
...
});
ZCRMRestClient.generateAuthTokens(user_identifier,grant_token).then(function(auth_response){
console.log("access token :"+auth_response.access_token);
console.log("refresh token :"+auth_response.refresh_token);
console.log("expires in :"+auth_response.expires_in);
});
This will be handled by sdk itself if the access and refresh token is generated by sdk.Developer need not call this explicitly.
ZCRMRestClient.generateAuthTokenfromRefreshToken(user_identifier,refresh_token).then(function(auth_response){
console.log("access token :"+auth_response.access_token);
console.log("refresh token :"+auth_response.refresh_token);
console.log("expires in :"+auth_response.expires_in);
});
var input ={};
input.module = "Leads";
var params = {};
params.page = 0;
params.per_page = 5;
input.params = params;
crmclient.API.MODULES.get(input).then(function(response){
var result = "<html><body><b> Top 5 Leads</b>";
var data = response.body;
data = JSON.parse(data);
data = data.data;
for (i in data){
var record = data[i];
var name = record.Full_Name;
result+="<br><span>"+name+"</span>";
}
result+="</body></html>";

As appearing in the hierarchy, zcrmsdk entity class has instance variables to fetch its own properties and to fetch data of its immediate child entities through an API call.
For example, to call an API to get module data, the request should be zcrmsdk.API.MODULES.{operation_type}. The operation types can be GET, POST, PUT, DELETE or CREATE.
All API calls will give the actual API response given by Zoho APIs, except file download.
For file download, the response will contain an extra field filename.
All errors will be thrown explicitly and care should be taken in catching the same.
