Kaizen #17 - PHP SDK

Kaizen #17 - PHP SDK

Hello everyone!
Welcome to yet another post in the Kaizen series.
This week, we are going to discuss the PHP SDK.

PHP Software Development Kit

PHP SDK allows you to create client PHP applications that can be integrated 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 PHP SDK acts as a middleware between Zoho CRM and Client PHP Application.



What can you do with the PHP SDK?
  • You can use the PHP SDK to exchange data between Zoho CRM and the client PHP application. 
  • Authenticate your application easily every time you sync data between Zoho CRM and the client PHP application, as the SDK takes care of generating the access/refresh tokens automatically. 

Installing the PHP SDK
You can install the PHP SDK for Zoho CRM through the Composer—a dependency manager for PHP applications. 

The pre-requisites for the client PHP application, before you start using the PHP SDK are:
  • The client app must have PHP 5.6 or above with a curl extension.
  • The client app must have the PHP SDK installed through Composer. 
  • The ZCRMRestClient::initialize($configuration) function must be called once while starting the client app. It contains the configuration details as key-value pairs.

PHP SDK and the PHP client application
  1. Include the following line to your client application (wherever you intend to use the PHP SDK) to access all the functionalities of the PHP SDK.

    require ‘vendor/autoload.php’
  2. Include the namespaces of the class in the "use" statement. For instance, if you use the ZCRMRestclient class, you must add the following.

    use zcrmsdk\crm\setup\restclient\ZCRMRestClient;

How to start using the PHP SDK?
  • Step-1: Prerequisite: Register your application
  • Step-2: Install the PHP SDK
  • Step-3: Authenticate the client application
  • Step-4: Knowledge Base: Token Persistence
  • Step-5: Initialization
Step-1: Prerequisite: Register your application

All the Zoho CRM APIs are authenticated by the OAuth2.0 standards. It is mandatory to authenticate the client application with Zoho.

2. Click ADD CLIENT.


3. Choose a client type. For instance, Self Client.



4. Choose the Client Type, and click CREATE. 


In the case of a web-based client, you need to specify the Client Name, Homepage URL and redirect URIs. 


5. Once you successfully register your self-client, you will receive a Client ID and Client Secret.


Step-2: Install the PHP SDK

Installing Composer 
As discussed earlier, you can install the PHP SDK through the Composer. To install the composer:

Operating System
Procedure
Mac/Linux
Run the following command in your terminal: curl -sS https://getcomposer.org/doc/00-intro.md#installation-linux-unix-osx
Windows
Click here to download the .exe file and install composer.

Installing the PHP SDK through the Composer
  1. Navigate to the workspace of your client app.
  2. Run the following command in the workspace of your client app.

    composer require zohocrm/php-sdk

  3. Once you run this command, the system installs the PHP SDK and creates a package named vendor in the workspace of your client app.


Step-3: Authenticate the client application

You must authenticate the client PHP application before it can use the PHP SDK. To authenticate the client PHP application, pass the configuration associative array to the initialization process.

  1. Create $configuration associative array. It must contain the authentication credentials required.
  2. The configuration associative array must then be passed using the ZCRMRestClient::initialize($configuration); function.
Configuration associative array

You must add the configuration values to the PHP associative array (key-value pair) and pass it as an argument to the ZCRMRestclient::initialize($configuration); function. Below is the list of keys that are to be in the associative array.


Key
Description
client_id, client_secret
mandatory
You can get these details after registering your client.
redirect_uri
mandatory for a web based client
The redirect URI of your web-based PHP client application.
currentUserEmail
mandatory
It is the email ID of the current user. You can set it in two ways:
a. Through the currentUserEmail key in the configuration associative array (or)
b. Through the ZCRMRestClient::setCurrentUserEmailId({user_email_id}) line in the code.
fileUploadUrl
Mandatory when using the Bulk Write API
The value for this key must be https://content.zohoapis.com
applicationLogFilePath
optional
The SDK automatically creates a file to store the log information. The absolute file path of the folder in which the system must create the log file must be specified. The default file name is the ZCRMClientLibrary.log. If not specified, the system creates the file inside the project.
sandbox
optional
Represents whether to make API calls from the sandbox account.
true: Make the API calls from the sandbox account.
false: Do not make the API calls from the sandbox account. This is the default value.
apiBaseUrl
optional
Represents the URL to make API calls. It denotes the domain of the user. The possible values are:
www.zohoapis.com (default)
www.zohoapis.eu
www.zohoapis.com.cn

apiVersion
optional
Represents the API version. Specify the value as v2 (default).
access_type
optional
Specify the value as offline
There is no support for Online OAuth client in PHP SDK as of now.
accounts_url
optional
persistence_handler_class
optional
The implementation of ZohoOAuthPersistenceInterface
token_persistence_path
optional
The absolute path to the folder that contains zcrm_oauthtokens.txt 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. 
persistence_handler_class_name
optional
The name of the custom class for persistence. This key is available only in PHP SDK 2.0.7 and above versions.
db_port
optional
You can specify this key if you want to use DB persistence. 
The default value is 3306.
db_username, db_password
optional
Specify the username and password of your database. The default value for db_username is root.
host_address
optional
The address of the machine in which the MySQL server is running. The default value is 'localhost'. This key is available only in PHP SDK 2.0.7 and above versions. 


Sample containing the mandatory keys alone:

$configuration=array("client_id"=>"1000.xxxxxxxxxxx"","client_secret"=>"831bxxxxxxxxxxxx","redirect_uri"=>"","currentUserEmail"=>"patricia@zylker.com"); 
ZCRMRestClient::initialize($configuration);

Sample containing all the keys:

$configuration=array("client_id"=>"1000.xxxxxxxxxxx",
            "client_secret"=>"831bxxxxxxxxxxxx",
            "redirect_uri"=>"redirect_uri",
            "currentUserEmail"=>"patricia@zylker.com",
            "applicationLogFilePath"=>"absolute/path/to/folder",
       "sandbox"=>"false","apiBaseUrl"=>"www.zohoapis.com",
            "apiVersion"=>"v2","access_type"=>"offline",
            "accounts_url"=>"https://accounts.zoho.com",
            "persistence_handler_class"=>"absolute/file/path/to/persistence/implementation",
            "token_persistence_path"=>"absolute/path/to/folder/zcrm_oauthtokens.txt", //should not contain "zcrm_oauthtokens.txt"
            "persistence_handler_class_name"=>"Persistence_class_name",
            "fileUploadUrl"=>"https://content.zohoapis.com"); 
ZCRMRestClient::initialize($configuration);


Step-4: Token Persistence

Your application should retain tokens (grant, access, refresh tokens) to automate the process of data-sync between your PHP application and Zoho CRM.

You can persist tokens in your application in three ways:

  • a. Using a Database
  • b. Using a File
  • c. Custom Persistence

a. Using a Database

If you prefer using database persistence, you can use the MySQL. 

Prerequisites while using the database persistence

  • The name of the database must be zohooauth.
  • There must be a table oauthtokens with columns
    a. useridentifier (varchar(100))
    accesstoken (varchar(100))
    refreshtoken (varchar(100))
    expirytime (bigint)
b. Using a File

This type of persistence uses a file to read and write OAuth tokens. The file persists the token of a single user. So, it is best used for the 'self-client' type of authentication since it involves only one user.  If you prefer using the file persistence, you must create an empty file in the local drive named zcrm_oauthtokens.txt. Further, set the file path in the token_persistence_path, of the $configuration associative array. Do not include "zcrm_oauthtokens.txt" in the path.

For example, if the file is in a folder named "TokenStorage", then

token_persistence_path="{path/to/TokenStorage}"


c. Custom Persistence

From the PHP SDK version 2.0.0, you can have your own implementation of persistence. 
You must mention the name of the persistence class in the persistence_handler_class_name key of configuration associative array. Provide the file path of the PHP file that implements the custom persistence, in the persistence_handler_class key of the configuration associative array. The class must implement the ZohoOAuthPersistenceInterface.

You must write an implementation of the inbuilt ZohoPersistenceHandler interface, with the following methods:
  • getOAuthTokens($userEmailId)—invoked to fetch the saved tokens. This method should return ZohoOAuthTokens object for the library to process it.
  • saveOAuthData(ZohoOAuthTokens tokens)—invoked to store the tokens.
  • deleteOAuthTokens($userEmailId)— invoked to delete the tokens.

Step-5: Initialization

Once you define the OAuth configuration, you can initialize the PHP client application.
You need to generate the tokens (grant/access/refresh) to run the app.

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.

$configuration =array("client_id"=>"1000.xxxxxxxxxxx","client_secret"=>"831bxxxxxxxxxxxx","redirect_uri"=>"","currentUserEmail"=>"patricia@zylker.com");
ZCRMRestClient::initialize($configuration);
$oAuthClient = ZohoOAuth::getClientInstance();
$grantToken = "paste_the_self_authorized_grant_token_here";
$oAuthTokens = $oAuthClient->generateAccessToken($grantToken);

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 for 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.

App Startup

Invoke the following line of code every time you start your client app.

$configuration =array("client_id"=>"1000.xxxxxxxxxxx","client_secret"=>"831bxxxxxxxxxxxx","redirect_uri"=>"","currentUserEmail"=>"patricia@zylker.com");
ZCRMRestClient::initialize($configuration);

                                                                                                    Hello! I am Zoho admin in a company and we want to use Zoho Project to manage projects, but after a few days of testing we are not able to "hide" the Developer Space from all kind of users except the admin. To sum up, I want to hide this for all users.
