Kaizen #16 - Python SDK

Kaizen #16 - Python SDK

Hello everyone!
Welcome back to another week of Kaizen!
This week, we will discuss the Python SDK.

What is the Python SDK for Zoho CRM?

Python SDK allows you to create client Python applications that you can integrate with Zoho CRM, effortlessly. It serves as a wrapper for the REST APIs, thus making it easier to use the services of Zoho CRM.

Here is a sample of how the SDK acts as a middle ware between Zoho CRM and a client Python Application.




What can you do with the Python SDK?
  • Exchange data between Zoho CRM and the client application where the CRM entities are modelled as classes.
  • Authenticate your application easily every time you sync data between Zoho CRM and your application, as the SDK takes care of generating the access/refresh tokens automatically.

Environment Setup
How to Start using the Python SDK?

Follow the below steps:
  • Step-1: Register your application (Self Client or Web-based client)
  • Step-2: Install the SDK
  • Step-3: Import the SDK in your project
  • Step-4: Initialize the SDK
    4.a. Choose the token persistence method
    4.b. Setup the configuration dictionary
    4.c. Generate the tokens
  • Step-5: Connect to Zoho CRM through the available methods
Let us now discuss these steps in detail.

Step-1: Register your application
All the Zoho CRM APIs are authenticated by the OAuth2.0 standards. It is mandatory to authenticate your application with Zoho.
You can register your application either as a Self Client (single user app) or a web-based app (multiple users app).

1.a. Self Client
  • Go to https://api-console.zoho.com.
  • Click ADD CLIENT.
  • Choose the Client Type as Self Client, and click CREATE.
  • You will receive a client ID and a client secret upon successful registration.

1.b. Web-based Client
  • Go to https://api-console.zoho.com.
  • Click ADD CLIENT.
  • Choose the client as Web based and click CREATE NOW.
  • Specify the client name, homepage URL of your application's UI, and a redirect URI to which you want to redirect the users after they grant consent to your application.
  • Click CREATE.
  • Your client ID and client secret will be displayed.
Step-2: Install the SDK

You can install the Python SDK through pip. Pip is a tool for dependency management in Python.

To install the SDK, run the below command in your Python IDE.

pip install zcrmsdk

This command installs the Python and creates a package named zcrmsdk in the installation directory of python (Example: '/Library/Python/2.7/site-packages').

Note
You must also have the Python requests installed. Run the command pip install requests to install them.

Step-3: Import the SDK in your project

Use the below statement in your IDE to import the downloaded SDK in your code.

import zcrmsdk

You can also set an alias for the imported SDK module. Run the below command to import the SDK in a custom name.


import zcrmsdk as your_custom_name

Note that you must use this name while referencing to any class in the SDK.

Example:

import zcrmsdk as my_zoho_sdk
my_zoho_sdk.ZCRMRestClient.initialize(config)

Step-4: Initialize the SDK 

Initializing the SDK involves the following steps.

  • Step 4.a - Choosing the token persistence method
  • Step 4.b - Setting up the configuration dictionary
  • Step 4.c - Generating the tokens

4.a. Token Persistence
Your application should retain tokens (grant, access, and refresh tokens) to automate the process of data sync between your python application and Zoho CRM.

You can persist (store) the tokens in three ways.
  1. MySQL Persistence (default)
  2. File Persistence
  3. Custom DB Persistence

4.a.1. MySQL Persistence

When you want to store the tokens in the MySQL DB, run the below command to install the necessary package.

pip install mysql-connector

In this case, you must include the following keys in the configuration dictionary (discussed in the next section), along with other mandatory keys.

"mysql_username": "root",
"mysql_password": "*****",
"mysql_port":" port_number"

Note
When you use MySQL persistence, ensure that
  • MySQL runs in the same machine serving at the mentioned port (The default port is 3306.)
  • There is a database named zohooauth.
  • There is a table name oauthtokens with the columns useridentifier (varchar(100)), accesstoken (varchar(100)), refreshtoken (varchar(100)) and expirytime (bigint).

4.a.2. File Persistence
If you want to store the tokens in a file, you can create a file named zcrm_oauthtokens.pkl and provide the absolute path of the directory containing this file in the below key of the configuration array.

"token_persistence_path": "path_to_the_folder_containing_the pkl_file"

If you do not create this file, the SDK itself creates this file in the path you have specified, and persists the tokens there.
Note: This method is recommended only for self client apps.

4.a.3. Custom DB Persistence
To use custom DB persistence, you must
  • Implement AbstractBaseClass (AbstractZohoOAuthPersistence from OAuthClient.py), and write a custom implementation of the following functions:
    get_oauthtokens(user_email)
    save_oauthtokens(oauthtokens)
    delete_oauthtokens(user_email)
Include the following keys in the configuration dictionary, along with other mandatory keys.

"persistence_handler_class": "ClassName of the custom implementation",
"persistence_handler_path": "Absolute path of the module (.py file)"

4.b. Configuration dictionary
The below table contains the list of keys you must include in the configuration dictionary based on the type of persistence.

Mandatory keys

File Persistence
MySQL Persistence
Custom DB Persistence
client_id
client_id
client_id
client_secret
client_secret
client_secret
redirect_uri
redirect_uri
redirect_uri
token_persistence_path
mysql_username
persistence_handler_class
--
mysql_password
persistence_handler_path
--
mysql_port
--
currentUserEmail
currentUserEmail
currentUserEmail

Optional keys

File Persistence
MySQL Persistence
Custom DB Persistence
applicationLogFilePath
applicationLogFilePath
applicationLogFilePath
sandbox
sandbox
sandbox
access_type
access_type
access_type
accounts_url
accounts_url
accounts_url
apiBaseUrl
apiBaseUrl
apiBaseUrl
apiVersion
apiVersion
apiVersion

Where,
  • client_id, client_secret, and redirect_uri - Client details you received after registering your application. For self client apps, you can pass a dummy value for the redirect uri.
  • token_persistence_path - The path to store the OAuth tokens in the file. This key is mandatory if you want to use file persistence. If you include this key, this method takes precedence over other persistence methods.
  • mysql_username, mysql_password, mysql_port - The MySQL username, password, and the port, respectively.
  • persistence_handler_class - Name of the class of the custom implementation for persistence. This key is mandatory if you want to use custom persistence.
  • persistence_handler_path - Absolute path of the module (.py file). This key is mandatory if you want to use custom persistence.
  • applicationLogFilePath - The absolute path to log the exceptions during the usage of the SDK.
  • sandbox - Boolean key to make API calls to the sandbox environment. The value true makes API calls to the sandbox. Default value is false.
  • access_type - Must be set to offline as the SDK does not support online OAuth client, now.
  • accounts_url - The domain-specific accounts URL from which you generate the tokens.
  • apiBaseUrl - The domain-specific API URL from which you make API calls. For users from domains other than the US, this key is mandatory.
  • apiVersion - Represents the version of the CRM APIs. The value is v2.
  • currentUserEmail - The email ID of the current user. When you do not specify this value, the SDK throws an exception. This key is mandatory in the configuration dictionary for self-client apps.

For web-based apps, set the user Email ID in the current thread as an attribute.

threading.current_thread().setattr('current_user_email','user@email.com')

Below is a configuration dictionary with all the keys. 

config = {
"apiVersion":"v2",
"currentUserEmail":"email@gmail.com"
"sandbox":"False"
"applicationLogFilePath":"",
"client_id":"1000.3xxxxxxxxxxxxxxxxxxxxxxxxX0YW",
"client_secret":"29xxxxxxxxxxxxxxxxxxxxxxxxxxxxx7e32",
"redirect_uri":"https://www.abc.com",
"token_persistence_path":"/Users/Zoho/Desktop/PycharmProjects",//For File Persistence
"access_type":"offline",
//Use the below keys for MySQL DB persistence
"mysql_username":"",
"mysql_password":"",
"mysql_port":"3306",
//Use the below keys for custom DB persistence
"persistence_handler_class" : "Custom",
"persistence_handler_path": "/Users/Zoho/Desktop/PythonSDK/CustomPersistance.py"
}

Now that you have created and registered your app with Zoho, you must authenticate it. 
Pass the configuration dictionary in the method ZCRMRestClient.initialize(config) and authenticate your app.

4.c. Generating the tokens

As the V2 Zoho CRM APIs follow the OAuth2.0 protocol, it is mandatory to authorize the OAuth2.0 app before using the SDK functions with an access token.
You can generate an access token from a grant token.
You can generate the grant token in two ways based on the type of client.

For Self Client Applications
  1. Log in to Zoho and go to Zoho Developer Console.
  2. Select your Self Client.
  3. Provide the necessary scopes separated by commas, along with the scope aaaserver.profile.READ.
  4. Select the Time Duration from the drop-down. This is the time the grant token is valid for.
  5. Provide a description for the scopes. Click GENERATE.
  6. Copy the grant token.

For Web-based Applications

It is the responsibility of your client app to generate the grant token for the users trying to login.
Your Application's UI must have the Login with Zoho option to open the grant token URL of Zoho, which would prompt for the user's OAuth2.0 authorization.
Upon the successful login of the user, the grant token will be sent as a parameter to your registered redirect URL.

Generating an access token from the grant token
Use the below code snippet in your main class.

zcrmsdk.ZCRMRestClient.initialize(config)
oauth_client = zcrmsdk.ZohoOAuth.get_client_instance()
grant_token = "paste_grant_token_here"
oauth_tokens = oauth_client.generate_access_token(grant_token)

Note
  • The code snippet to generate the access token from the grant token is valid only once per grant token. If the grant token expires before you generate the access token, you must generate a new grant token only.
  • Generating access and refresh tokens is a one-time process. After the tokens are generated the first time, the SDK persists them based on the keys defined in the configuration dictionary, and refreshes the access token as and when required.

Step-5: Connect to Zoho CRM through the available methods

Large, uncompressed images. By optimizing your images, your store loads faster and creates a smoother shopping experience leading to higher sales. It also indirectly improves SEO.

Please change this, it is not a good process to have to bother other users to change a report or change users within a report.
