In Magento 2, the term ‘integration' defines the third-party application that uses OAuth for authentication. It allows Magento developers to specify which resources the application can access.

Magento 2 APIs, by default, support CRM, ERP, accounting, and PIM systems and marketing automation. You can enable your third-party services to call the Magento 2 APIs by seeking Magento Development Services to create an integration manually or programmatically. This article provides the instructions to create Magento 2 API integration manually or programmatically.

How to Create Magento 2 API Integrations Manually?

A professional Magento development company follows these steps to add a new integration in Magento 2 manually:

Step 1: Open the Magento 2 backend by clicking the System on the admin panel and selecting Integration in the Extension section.

Step 2: Click Add a New Integration in the upper-right corner and enter all necessary details in the ‘Integration Info' section. 

  • The Name field asks for the integration's name.
  • The Email field asks for the contact email address.
  • The Callback URL field asks to enter the callback URL where OAuth credentials can be sent whenever using OAuth to exchange tokens.
  • The Identity Link URL field asks to enter the identity link URL to redirect users to a third-party account.
  • In the panel, choose API.
  • In the Resource Access field, choose All or Custom. On choosing Custom, you can mark the checkbox of each required resource.

Step 3: Hit the Save button to save the configuration and check the result.

How to Create Magento 2 API Integrations Programmatically?

Integrations in Magento 2 are handled within the Magento_Integration module. You can hire magento developer to create Magento 2 API integration via XML configuration files. 

Step 1: Creating a skeleton module

  • In Magento 2, integration modules are placed under /app/code//
  • The configuration file for a module is to be defined as etc/module.xml. Navigate to the etc. directory and create the module.xml file by providing the module name, module version, and dependencies. 
  • Next, you need to add your composer.json file to ensure that Composer can install and update the libraries required by your module.
  • Add a registration.php file to register your module with the Magento2 system.
  • Add the install file to generate an integration during the module installation process.

Step 2: Adding integration CML setting files

The Magento Integration module will simplify the integration-defining process. Your Magento development professional can configure integrations programmatically by using the following:

api.xml in the etc/integration directory to define needed resources

config.xml in the etc/integration directory to define an integration. 

Step 3: Defining the required resources

The file etc/integration/api.xml will specify the API resources the integration can access. You should evaluate the permissions defined in each module's etc/acl.xml file to know the resources that need to be accessed by an integration. 

Step 4: Defining the integration

Your module will have the option to include values in the configuration file and, thus, automatically pre-configure the integration. Hire a Magento 2 Developer to enable this functionality by making the necessary updates to the config.xml file in the etc/integration directory.

Step 5: Installing the module

It's now time to install the module to trigger the setup script for creating an integration. Go to Systems > Extensions > Integrations and tap the integration you want to see the result.

Conclusion

To work with Magento Integration, you should hire a reliable Magento 2 Development Company that understands how Magento 2 and the external application handle OAuth communication. In addition, the developers should know the manual and programmatic process of creating Magento 2 integrations.
