Configuration

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

Follow the below steps to configure the SDK.

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

   Copy to Clipboard
   import {Levels,Logger} from "@zohocrm/typescript-sdk-2.0/routes/logger/logger"
   import {LogBuilder} from "@zohocrm/typescript-sdk-2.0/routes/logger/log_builder"
   /*
   * 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: Logger = new LogBuilder()
   .level(Levels.INFO)
   .filePath("/Users/user_name/Documents/node_sdk_logs.log")
   .build();
   

2. Create an instance of UserSignature class that identifies the current user.

   Copy to Clipboard
   import {UserSignature} from "@zohocrm/typescript-sdk-2.0/routes/user_signature"
   //Create an UserSignature instance that takes user Email as parameter
   let user: UserSignature = new UserSignature("abc@zoho.com");
   

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

   Copy to Clipboard
   import {USDataCenter} from "@zohocrm/typescript-sdk-2.0/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();
   

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

   Copy to Clipboard
   import { OAuthToken } from "@zohocrm/typescript-sdk-2.0/models/authenticator/oauth_token"
   import { OAuthBuilder } from "@zohocrm/typescript-sdk-2.0/models/authenticator/oauth_builder"
   
   /*
   * Create a Token instance that requires the following
   * clientId -> OAuth client id.
   * clientSecret -> OAuth client secret.
   * refreshToken -> REFRESH token.
   * accessToken -> Access token.
   * grantToken -> GRANT token.
   * id -> User unique id.
   * redirectURL -> OAuth redirect URL.
   */
   //Create a Token instance
   // if refresh token is available
   // The SDK throws an exception, if the given id is invalid.
   let token: OAuthToken = new OAuthBuilder()
   .id("id")
   .build();
   
   // if grant token is available
   let token: OAuthToken = new OAuthBuilder()
   .clientId("clientId")
   .clientSecret("clientSecret")
   .grantToken("grantToken")
   .redirectURL("redirectURL")
   .build();
   
   // if ID (obtained from persistence) is available
   let token: OAuthToken = new OAuthBuilder()
   .clientId("clientId")
   .clientSecret("clientSecret")
   .refreshToken("refreshToken")
   .redirectURL("redirectURL")
   .build();
   
   // if access token is available
   let token: OAuthToken = new OAuthBuilder()
   .accessToken("accessToken")
   .build();
   

5. 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.

   Copy to Clipboard
   import {DBStore} from "@zohocrm/typescript-sdk-2.0/models/authenticator/store/db_store"
   import {FileStore} from "@zohocrm/typescript-sdk-2.0/models/authenticator/store/file_store"
   import {DBBuilder} from "@zohocrm/typescript-sdk-2.0/models/authenticator/store/db_builder";
   
   /*
   * 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: DBStore = new DBStore().build();
   
   let tokenstore: DBStore = new DBBuilder()
   .host("hostName")
   .databaseName("databaseName")
   .userName("userName")
   .portNumber("portNumber")
   .tableName("tableName")
   .password("password")
   .build();
   
   //let tokenstore: FileStore = new FileStore("/Users/userName/tssdk-tokens.txt")
   

6. Create an instance of SDKConfig containing the SDK configuration.

   Copy to Clipboard
   import {SDKConfig} from "@zohocrm/typescript-sdk-2.0/routes/sdk_config";
   import {SDKConfigBuilder} from "@zohocrm/typescript-sdk-2.0/routes/sdk_config_builder";
   
   /*
    * 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: SDKConfig = new SDKConfigBuilder().pickListValidation(false).autoRefreshFields(true).build();
   

7. 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

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

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

   Copy to Clipboard
   import { RequestProxy} from "@zohocrm/typescript-sdk-2.0/routes/request_proxy"
   import { ProxyBuilder} from "@zohocrm/typescript-sdk-2.0/routes/proxy_builder"
   
   /*
    * RequestProxy class takes the following parameters
    * host -> Host
    * port -> Port Number
    * user -> User Name. Default null.
    * password -> Password. Default null
    */
   let requestProxy: RequestProxy = new ProxyBuilder()
   .host("proxyHost")
   .port("proxyPort")
   .user("proxyUser")
   .password("password")
   .build();
     

9. Initialize the SDK and make API calls.
