Overview

Zoho CRM TypeScript SDK offers a way to create client TypeScript applications that can be integrated with Zoho CRM.

Registering a Zoho Client

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://api-console.zoho.com/

• Click ADD CLIENT.

• Choose the Client Type.

• Enter Client Name, Client Domain or Homepage URL and Authorized Redirect URIs then click CREATE.

• Your Client app will be created.

• Select the created OAuth client.

• Generate grant token by providing the necessary scopes, time duration (the duration for which the generated token is valid) and Scope Description.

Environmental Setup

TypeScript SDK is installable through npm. npm is a tool for dependency management in TypeScript. SDK expects the following from the client app:

• Client app must have Node(version 12 and above)

• TypeScript SDK must be installed in the client app through npm.

Including the SDK in your project

• Install Node from nodejs.org (if not installed).

• Install TypeScript NPM package.

  npm install -g typescript
  

• Install TypeScript SDK

  • Navigate to the workspace of your client app.
  • Run the command below:

  npm install @zohocrm/typescript-sdk-7.0
  

• The TypeScript SDK will be installed and a package named @zohocrm/typescript-sdk-7.0 will be created in the local machine.

• Another method to install the SDK:

  • Add dependencies to the package.json of the node server with the latest version (recommended)
  • Run npm install in the directory which installs all the dependencies mentioned in package.json.

Dependencies

• Dependencies that should be included in your project

  • install form-data

    npm i form-data
    

  • install ts-node

    npm i ts-node
    

  • install typescript

    npm i typescript
    

  • install got

    npm i got
    

  • install moment-timezone

    npm i moment-timezone
    

  • install mysql

    npm i mysql
    

  • install tunnel

    npm i tunnel
    

  • install winston

    npm i winston
    

  • install @types/mysql

    npm i @types/mysql
    

  • install @types/tunnel

    npm i @types/tunnel
    

Token Persistence

Token persistence refers to storing and utilizing the authentication tokens that are provided by Zoho. Token persistence enables the SDK to automatically refresh the access token after initialization using the refresh token without the need for user intervention. There are three ways provided by the SDK in which persistence can be utilized. They are File Persistence, DataBase Persistence, and Custom Persistence.Please note that the default method of token persistence provided by the Zoho CRM SDK is File persistence

Table of Contents

• DataBase Persistence

• File Persistence

• Custom Persistence

Implementing OAuth Persistence

Once the application is authorized, OAuth access and refresh tokens can be used for subsequent user data requests to Zoho CRM. Hence, they need to be persisted by the client app.

The persistence is achieved by writing an implementation of the inbuilt TokenStore Interface, which has the following callback methods.

• findToken(token : Token) - invoked before firing a request to fetch the saved tokens. This method should return implementation Token Interface object for the library to process it.

• saveToken(token : Token) - invoked after fetching access and refresh tokens from Zoho.

• deleteToken(id) - invoked before saving the latest tokens.

• getTokens() - The method to retrieve all the stored tokens.

• deleteTokens() - The method to delete all the stored tokens.

• findTokenById(id) - The method to retrieve the user's token details based on unique ID.

Note:

• id is a string.

• token is an instance of Token interface.

DataBase Persistence

Database persistence is a technique that involves storing and retrieving data from a database. In case the user prefers to use default DataBase persistence, MySQL can be used.

• Create a table in your Database with required columns

  • id varchar(10)

  • user_name varchar(255)

  • client_id varchar(255)

  • client_secret varchar(255)

  • refresh_token varchar(255)

  • access_token varchar(255)

  • grant_token varchar(255)

  • expiry_time varchar(20)

  • redirect_url varchar(255)

  • api_domain varchar(255)

Note:

• Custom database name and table name can be set in DBStore instance.

MySQL Query

CREATE TABLE oauthtoken (
  id varchar(10) NOT NULL,
  user_name varchar(255),
  client_id varchar(255),
  client_secret varchar(255),
  refresh_token varchar(255),
  access_token varchar(255),
  grant_token varchar(255),
  expiry_time varchar(20),
  redirect_url varchar(255),
  api_domain varchar(255),
  primary key (id)
);

Create DBStore object

import * as ZOHOCRMSDK from "@zohocrm/typescript-sdk-7.0";

/*
* hostName -> DataBase host name. Default value "localhost"
* databaseName -> DataBase name. Default  value "zohooauth"
* userName -> DataBase user name. Default value "root"
* password -> DataBase password. Default value ""
* portNumber -> DataBase port number. Default value "3306"
* tableName -> Table Name. Default value "oauthtoken"
*/

let tokenstore: ZOHOCRMSDK.DBStore = new ZOHOCRMSDK.DBBuilder()
.host("hostName")
.databaseName("databaseName")
.userName("userName")
.portNumber("portNumber")
.tableName("tableName")
.password("password")
.build();

File Persistence

In case of default File Persistence, the user can persist tokens in the local drive, by providing the the absolute file path to the FileStore object.

• The File contains

  • id

  • user_name

  • client_id

  • client_secret

  • refresh_token

  • access_token

  • grant_token

  • expiry_time

  • redirect_url

  • api_domain

Create FileStore object

import * as ZOHOCRMSDK from "@zohocrm/typescript-sdk-7.0";
/*
 * FileStore takes the following parameter
 * 1 -> Absolute file path of the file to persist tokens
*/
let tokenstore: ZOHOCRMSDK.FileStore = new ZOHOCRMSDK.FileStore("/Users/username/Documents/ts_sdk_tokens.txt");

Custom Persistence

Users can create their own logic for storing and retrieving authentication tokens using the custom persistence technique.To use Custom Persistence, the user must implement TokenStore Interface and override the methods.

import * as ZOHOCRMSDK from "@zohocrm/typescript-sdk-7.0";

export class CustomStore implements ZOHOCRMSDK.TokenStore.MasterModel {
    constructor() {
    }

    /**
     *
     * @param {Token} token A Token (@zohocrm/typescript-sdk-7.0/models/authenticator/oauth_token) class instance.
     * @returns A Token class instance representing the user token details.
     * @throws {SDKException} if any error occurs.
     */
    async findToken(token: ZOHOCRMSDK.Token.MasterModel): Promise<ZOHOCRMSDK.Token.MasterModel | null | void> {
        // Add code to get the token
        return undefined;
    }

    /**
     *
     * @param {Token} token A Token (@zohocrm/typescript-sdk-7.0/models/authenticator/oauth_token) class instance.
     * @throws {SDKException} if any error occurs.
     */
    async saveToken(token: ZOHOCRMSDK.Token.MasterModel): Promise<void>{
        // Add code to save the token
    }

    /**
     *
     * @param {String} id - A String representing the unique ID
     * @throws {SDKException} if any error occurs.
     */
    async deleteToken(id : string): Promise<void> {
        // Add code to delete the token
    }

    /**
     * @returns {Array} - An array of Token class instances
     * @throws {SDKException}
     */
    async getTokens(): Promise<Array<ZOHOCRMSDK.Token.MasterModel> | null> {
        //Add code to retrieve all the stored tokens.
    }

    /**
     * @throws {SDKException}
     */
    async deleteTokens(): Promise<void> {
        //Add code to delete all the stored tokens.
    }

    /**
     * This method is used to retrieve the user token details based on unique ID
     * @param {String} id - A String representing the unique ID
     * @return {Token} A Token class instance representing the user token details.
     * @throws SDKException
     */
    findTokenById(id: string): Promise<ZOHOCRMSDK.Token.MasterModel | null | void> {
      // Add code to get the token using unique id
    }
}

Configuration

Before you get started with creating your TypeScript application, you need to register your client and authenticate the app with Zoho.

Mandatory Keys	Optional Keys
environment	logger
token	tokenstore
	sdkConfig
	requestProxy
	resourcePath

---

The environment key contains the domain information to make API calls. The token key represents the OAuth info, including the clientID, clientSecret, grantToken, redirectURL, refreshToken or accessToken depending on the flow that you use. Refer to ##create an instance of OAuthToken## for more details.

• Configure API environment which decides the domain and the URL to make API calls.

  import * as ZOHOCRMSDK from "@zohocrm/typescript-sdk-7.0";
  /*
   * Configure the environment
   * which is of the pattern Domain.Environment
   * Available Domains: USDataCenter, EUDataCenter, INDataCenter, CNDataCenter, AUDataCenter,JPDataCenter,CADataCenter
   * Available Environments: PRODUCTION(), DEVELOPER(), SANDBOX()
  */
  let environment: Environment = ZOHOCRMSDK.USDataCenter.PRODUCTION();
  

• Create an instance of ZOHOCRMSDK.OAuthToken with the information that you get after registering your Zoho client. In the context of token persistence, the grant token flow and refresh token flow involve storing and persisting the token. However, the access token flow does not involve token persistence and the access token is directly utilized for API calls. Depending on the tokens available with you, choose grantToken flow, refreshToken flow or accessToken flow.

  • By default, the findUser key is set to true, to set userSignature. However, this requires the ZohoCRM.users.READ and ZohoCRM.org.READ scopes to be mandatory. If you do not want to set userSignature, you must set the findUser key to false.

  • Use the followoing method for grantToken flow:

  let token: ZOHOCRMSDK.OAuthToken = new ZOHOCRMSDK.OAuthBuilder()
  .clientId("clientId")
  .clientSecret("clientSecret")
  .grantToken("grantToken")
  .redirectURL("redirectURL")
  .findUser(false)// by default true
  .build();
  

  • Use the following method for refreshToken flow:

  let token: ZOHOCRMSDK.OAuthToken = new ZOHOCRMSDK.OAuthBuilder()
  .clientId("clientId")
  .clientSecret("clientSecret")
  .refreshToken("refreshToken")
  .redirectURL("redirectURL")
  .findUser(false)// by default true
  .build();
  

  • Use the following method for accessToken flow:

  let token: ZOHOCRMSDK.OAuthToken = new ZOHOCRMSDK.OAuthBuilder()
  .accessToken("accessToken")
  .findUser(false)// by default true
  .build();
  

  • Use the following method for Id flow:

  let token: ZOHOCRMSDK.OAuthToken = new ZOHOCRMSDK.OAuthBuilder()
  .id("id")
  .build();
  

• Create an instance of ZOHOCRMSDK.Logger Class to log exception and API information.

  import * as ZOHOCRMSDK from "@zohocrm/typescript-sdk-7.0";
  /*
  * Create an instance of Logger Class that takes two parameters
  * level -> Level of the log messages to be logged. Can be configured by typing Levels "." and choose any level from the list displayed.
  * filePath -> Absolute file path, where messages need to be logged.
  */
  let logger: ZOHOCRMSDK.Logger = new ZOHOCRMSDK.LogBuilder()
  .level(ZOHOCRMSDK.Levels.INFO)
  .filePath("/Users/user_name/Documents/node_sdk_logs.log")
  .build();
  

• Create an instance of TokenStore to persist tokens, used for authenticating all the requests. By default, the SDK creates the sdk_tokens.txt file (parallel to node_modules folder) to persist the tokens.

  • Use the following method for DBStore

   /*
  * hostName -> DataBase host name. Default value "localhost"
  * databaseName -> DataBase name. Default  value "zohooauth"
  * userName -> DataBase user name. Default value "root"
  * password -> DataBase password. Default value ""
  * portNumber -> DataBase port number. Default value "3306"
  * tableName -> Table Name. Default value "oauthtoken"
  */
  let tokenstore: ZOHOCRMSDK.DBStore = new ZOHOCRMSDK.DBBuilder().build();
  
  let tokenstore: ZOHOCRMSDK.DBStore = new ZOHOCRMSDK.DBBuilder()
  .host("hostName")
  .databaseName("databaseName")
  .userName("userName")
  .portNumber("portNumber")
  .tableName("tableName")
  .password("password")
  .build();
  

  • Use the following method for FileStore

  let tokenstore: FileStore = new FileStore("absolute_file_path");
  

  • Use the following method for Custom Store

  let tokenstore = new CustomStore();
  

• Create an instance of ZOHOCRMSDK.SDKConfig containing the SDK configuration.

  import * as ZOHOCRMSDK from "@zohocrm/typescript-sdk-7.0";
  /*
   * By default, the SDK creates the SDKConfig instance
   * autoRefreshFields (default - false)
   * if true - all the modules' fields will be auto-refreshed in the background, every hour.
   * if false - the fields will not be auto-refreshed in the background. The user can manually delete the file(s) or refresh the fields using methods from ModuleFieldsHandler(utils/util/module_fields_handler.ts)
   *
   * pickListValidation (default - true)
   * A boolean field that validates user input for a pick list field and allows or disallows the addition of a new value to the list.
   * if true - the SDK validates the input. If the value does not exist in the pick list, the SDK throws an error.
   * if false - the SDK does not validate the input and makes the API request with the user’s input to the pick list
   */
  let sdkConfig: ZOHOCRMSDK.SDKConfig = new ZOHOCRMSDK.SDKConfigBuilder().pickListValidation(false).autoRefreshFields(true).build();
  

• Create an instance of ZOHOCRMSDK.RequestProxy containing the proxy properties of the user.

  import * as ZOHOCRMSDK from "@zohocrm/typescript-sdk-7.0";
  /*
   * RequestProxy class takes the following parameters
   * host -> Host
   * port -> Port Number
   * user -> User Name. Default null.
   * password -> Password. Default null
   */
  let requestProxy: ZOHOCRMSDK.RequestProxy = new ZOHOCRMSDK.ProxyBuilder()
  .host("proxyHost")
  .port("proxyPort")
  .user("proxyUser")
  .password("password")
  .build();
  

• The path containing the absolute directory path to store user specific files containing module fields information. By default, the SDK stores the user-specific files in a folder parallel to node_modules

  let resourcePath: string = "/Users/user_name/Documents/typescript-app";
  

Initializing the Application

Initialize the SDK using the following code.

import * as ZOHOCRMSDK from "@zohocrm/typescript-sdk-7.0";
export class Initializer {
    public static async initialize() {
        let logger: ZOHOCRMSDK.Logger = new ZOHOCRMSDK.LogBuilder()
        .level(ZOHOCRMSDK.Levels.INFO)
        .filePath("/Users/Documents/ts_sdk_log.log")
        .build();
        let environment: ZOHOCRMSDK.Environment = ZOHOCRMSDK.USDataCenter.PRODUCTION();
        let token: ZOHOCRMSDK.OAuthToken = new ZOHOCRMSDK.OAuthBuilder()
        .clientId("clientId")
        .clientSecret("clientSecret")
        .refreshToken("refreshToken")
        .redirectURL("redirectURL")
        .build();
        let tokenstore: ZOHOCRMSDK.DBStore = new ZOHOCRMSDK.DBBuilder()
        .host("hostName")
        .databaseName("databaseName")
        .userName("userName")
        .portNumber(3306)
        .tableName("tableName")
        .password("password")
        .build();
        // let store: ZOHOCRMSDK.FileStore = new ZOHOCRMSDK.FileStore("/Users/userName/ts_sdk_tokens.txt");
        let sdkConfig: ZOHOCRMSDK.SDKConfig = new ZOHOCRMSDK.SDKConfigBuilder().pickListValidation(false).autoRefreshFields(true).build();
        let resourcePath: string = "/Users/tssdk-application";
        let requestProxy: ZOHOCRMSDK.RequestProxy = new ZOHOCRMSDK.ProxyBuilder()
        .host("proxyHost")
        .port(0)
        .user("proxyUser")
        .password("password")
        .build();
        try {
            (await new ZOHOCRMSDK.InitializeBuilder())
                .environment(environment)
                .token(token)
                .store(tokenstore)
                .SDKConfig(sdkConfig)
                .resourcePath(resourcePath)
                .logger(logger)
                .initialize();
        } catch (error) {
            console.log(error);
        }

    }
}
Initializer.initialize()

• You can now access the functionalities of the SDK. Refer to the sample codes to make various API calls through the SDK.

Class Hierarchy

Responses and Exceptions

All SDK method calls return an instance of ZOHOCRMSDK.APIResponse.

After a successful API request, the getObject() method returns an instance of the ResponseWrapper (for GET) or the ActionWrapper (for POST, PUT, DELETE).

Whenever the API returns an error response, the getObject() returns an instance of APIException class.

ResponseWrapper (for GET requests) and ActionWrapper (for POST, PUT, DELETE requests) are the expected objects for Zoho CRM APIs’ responses

However, some specific operations have different expected objects, such as the following

SampleRecord.call();

• The program execution starts from call().

• The details of "user1" are is given in the variables user1, token1, environment1.

• Similarly, the details of another user "user2" is given in the variables user2, token2, environment2.

• The switchUser() function is used to switch between the "user1" and "user2" as required.

• Based on the latest switched user, the SampleRecord.getRecords(moduleAPIName) will fetch records.
