Your Client app would have been created and displayed by now.
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 into client app through npm.

Including the SDK in your project

You can include the SDK to your project using:

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
```
The TypeScript SDK will be installed and a package named @zohocrm/typescript-sdk 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.

Token Persistence

Token persistence refers to storing and utilizing the authentication tokens that are provided by Zoho. There are three ways provided by the SDK in which persistence can be utilized. They are DataBase Persistence, File Persistence and 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 Class, which has the following callback methods.

getToken(user : UserSignature, token : Token) - invoked before firing a request to fetch the saved tokens. This method should return implementation Token Class object for the library to process it.
saveToken(user: UserSignature, token : Token) - invoked after fetching access and refresh tokens from Zoho.
deleteToken(token : Token) - invoked before saving the latest tokens.
getTokens() - The method to retrieve all the stored tokens.
deleteTokens() - The method to delete all the stored tokens.

DataBase Persistence

In case the user prefers to use default DataBase persistence, MySQL can be used.

The database name should be zohooauth.
There must be a table name oauthtoken with columns.
- user_mail varchar(255)
- client_id varchar(255)
- refresh_token varchar(255)
- access_token varchar(255)
- grant_token varchar(255)
- expiry_time varchar(20)

MySQL Query

create table oauthtoken(id int(11) not null auto_increment, user_mail varchar(255) not null, client_id varchar(255), refresh_token varchar(255), access_token varchar(255), grant_token varchar(255), expiry_time varchar(20), primary key (id));

alter table oauthtoken auto_increment = 1;

Create DBStore object

import {DBStore} from "@zohocrm/typescript-sdk/models/authenticator/store/db_store";
/*
 * DBStore takes the following parameters
 * 1 -> DataBase host name. Default value "localhost"
 * 2 -> DataBase name. Default  value "zohooauth"
 * 3 -> DataBase user name. Default value "root"
 * 4 -> DataBase password. Default value ""
 * 5 -> DataBase port number. Default value "3306"
*/

let tokenstore: DBStore = new DBStore();

let tokenstore: DBStore = new DBStore("hostName", "dataBaseName", "userName", "password", "portNumber");

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 the following

user_mail
client_id
refresh_token
access_token
grant_token
expiry_time

Create FileStore object

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

Custom Persistence

To use Custom Persistence, the user must extend TokenStore Class (@zohocrm/typescript-sdk/models/authenticator/store/token_store) and override the methods.

import { TokenStore } from "@zohocrm/typescript-sdk/models/authenticator/store/token_store";

export class CustomStore implements TokenStore {

    constructor(){
    }

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

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

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

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

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

module.exports = {CustomStore}

Configuration

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

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

import {Levels,Logger} from "@zohocrm/typescript-sdk/routes/logger/logger"
/*
 * Create an instance of Logger Class that takes two parameters
 * 1 -> Level of the log messages to be logged. Can be configured by typing Levels "." and choose any level from the list displayed.
 * 2 -> Absolute file path, where messages need to be logged.
*/
let logger: Logger = Logger.getInstance(Levels.INFO, "/Users/user_name/Documents/ts_sdk_log.log");

Create an instance of UserSignature Class that identifies the current user.

import {UserSignature} from "@zohocrm/typescript-sdk/routes/user_signature"
//Create an UserSignature instance that takes user Email as parameter
let user: UserSignature = new UserSignature("abc@zoho.com");

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

import {USDataCenter} from "@zohocrm/typescript-sdk/routes/dc/us_data_center"
/*
 * Configure the environment
 * which is of the pattern Domain.Environment
 * Available Domains: USDataCenter, EUDataCenter, INDataCenter, CNDataCenter, AUDataCenter
 * Available Environments: PRODUCTION(), DEVELOPER(), SANDBOX()
*/
let environment: Environment = USDataCenter.PRODUCTION();

Create an instance of OAuthToken with the information that you get after registering your Zoho client.

import { OAuthToken,TokenType } from "@zohocrm/typescript-sdk/models/authenticator/oauth_token"
/*
 * Create a Token instance
 * 1 -> OAuth client id.
 * 2 -> OAuth client secret.
 * 3 -> REFRESH/GRANT token.
 * 4 -> token type.
 * 5 -> OAuth redirect URL.
*/
let token: OAuthToken = new OAuthToken("clientId", "clientSecret", "REFRESH/ GRANT Token", TokenType.REFRESH/TokenType.GRANT, "redirectURL");

Create an instance of TokenStore to persist tokens, used for authenticating all the requests.

import {DBStore} from "@zohocrm/typescript-sdk/models/authenticator/store/db_store"
import {FileStore} from "@zohocrm/typescript-sdk/models/authenticator/store/file_store"
/*
 * DBStore takes the following parameters
 * 1 -> DataBase host name. Default value "localhost"
 * 2 -> DataBase name. Default  value "zohooauth"
 * 3 -> DataBase user name. Default value "root"
 * 4 -> DataBase password. Default value ""
 * 5 -> DataBase port number. Default value "3306"
*/

let tokenstore: DBStore = new DBStore();

let tokenstore: DBStore = new DBStore("hostName", "dataBaseName", "userName", "password", "portNumber");

//let tokenstore: FileStore = new FileStore("/Users/userName/Documents/tssdk-tokens.txt")

Create an instance of SDKConfig containing the SDK configuration.

import {SDKConfig} from "@zohocrm/typescript-sdk/routes/sdk_config";
import {SDKConfigBuilder} from "@zohocrm/typescript-sdk/routes/sdk_config_builder";

/*
 * autoRefreshFields
 * 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
 * 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: SDKConfig = new SDKConfigBuilder().setPickListValidation(false).setAutoRefreshFields(true).build();

The path containing the absolute directory path (in the key resourcePath) to store user-specific files containing information about fields in modules.
```
let resourcePath: string = "/Users/user_name/Documents/typescript-app";
```

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

import { RequestProxy} from "@zohocrm/typescript-sdk/routes/request_proxy";

/*
 * RequestProxy class takes the following parameters
 * 1 -> Host
 * 2 -> Port Number
 * 3 -> User Name. Default null.
 * 4 -> Password. Default null
 */
let requestProxy: RequestProxy = new RequestProxy("proxyHost", 80, "proxyUser", "password");

Initializing the Application

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

Class Hierarchy

classdiagram

Responses and Exceptions

All SDK method calls return an instance of 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

Operations involving records in Tags
- RecordActionWrapper
Getting Record Count for a specific Tag operation
- CountWrapper
Operations involving BaseCurrency
- BaseCurrencyActionWrapper
Lead convert operation
- ConvertActionWrapper
Retrieving Deleted records operation
- DeletedRecordsWrapper
Record image download operation
- FileBodyWrapper
MassUpdate record operations
- MassUpdateActionWrapper
- MassUpdateResponseWrapper

GET Requests

The getObject() returns instance of one of the following classes, based on the return type.
- For application/json responses
  - ResponseWrapper
  - CountWrapper
  - DeletedRecordsWrapper
  - MassUpdateResponseWrapper
  - APIException
- For file download responses
  - FileBodyWrapper
  - APIException

POST, PUT, DELETE Requests

The getObject() returns instance of one of the following classes
- ActionWrapper
- RecordActionWrapper
- BaseCurrencyActionWrapper
- MassUpdateActionWrapper
- ConvertActionWrapper
- APIException
These wrapper classes may contain one or an array of instances of the following classes, depending on the response
- SuccessResponse Class, if the request was successful.
- APIException Class, if the request was erroneous.

For example, when you insert two records, and one of them was inserted successfully while the other one failed, the ActionWrapper will contain one instance each of the SuccessResponse and APIException classes.

All other exceptions such as SDK anomalies and other unexpected behaviours are thrown under the SDKException class.

Multi-User support in the TypeScript SDK

The TypeScript SDK (from version 1.x.x) supports both single-user and multi-user app.

Multi-user App

Multi-users functionality is achieved using Initializer's static switchUser() method.

//If proxy needs to be configured for the User
await Initializer.switchUser(user, environment, token, sdkConfig, requestProxy)

//Without proxy
await Initializer.switchUser(user, environment, token, sdkConfig)

To Remove a user's configuration in SDK. Use the below code

await Initializer.removeUserConfiguration(user, environment)

    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.
