To register your app:Visit this pagehttps://api-console.zoho.comClick onADD CLIENT.Choose theClient Type.EnterClient Name,Client DomainorHomepage URLandAuthorized Redirect URIsthen clickCREATE.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 SetupPython SDK is installable throughpip.pipis a tool for dependency management in Python. SDK expects the following from the client app.Client app must have Python(version 3 and above)Python SDK must be installed into client app throughpip.Including the SDK in your projectInstallPythonfrompython.org(if not installed).InstallPython SDKNavigate to the workspace of your client app.Run the command below:pipinstallzohocrmsdk2_0==5.x.xThe Python SDK will be installed in your client application.Token PersistenceToken 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.Table of ContentsDataBase PersistenceFile PersistenceCustom PersistenceImplementing OAuth PersistenceOnce 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 Abstract Base ClassTokenStore, which has the following callback methods.get_token(self, user,token)- invoked before firing a request to fetch the saved tokens. This method should return implementation of inbuiltToken Classobject for the library to process it.save_token(self, user,token)- invoked after fetching access and refresh tokens from Zoho.delete_token(self,token)- invoked before saving the latest tokens.get_tokens(self)- The method to get the all the stored tokens.delete_tokens(self)- The method to delete all the stored tokens.get_token_by_id(self, id, token)- The method to retrieve the user's token details based on unique ID.Note:user is an instance of UserSignature Class.token is an instance of Token Class.DataBase PersistenceIn case the user prefers to use default DataBase persistence,MySQLcan be used.The database name should bezohooauth.There must be a table nameoauthtokenwith the following columns.id int(11)user_mail 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)Note:Custom database name and table name can be set in DBStore instance.MySQL QueryCREATETABLEoauthtoken(idvarchar(255)NOTNULL,user_mailvarchar(255)NOTNULL,client_idvarchar(255),client_secretvarchar(255),refresh_tokenvarchar(255),access_tokenvarchar(255),grant_tokenvarchar(255),expiry_timevarchar(20),redirect_urlvarchar(255),primarykey(id))altertableoauthtokenauto_increment=1;Create DBStore objectfromzcrmsdk.src.com.zoho.api.authenticator.storeimportDBStore"""DBStore takes the following parameters1 -> DataBase host name.

By using multiple threads, you can make a Python program run faster and do multiple things simultaneously.Multithreading in a Multi-user AppMulti-threading for multi-users is achieved using Initializer's staticswitch_user()method.
