How to Create new API information for Integration in Magento 2

Today, my topic will point out the steps you need to follow to create API Intergration that means integrating your Magento store with a third-party API. The workflow of the API Integration is setting up the location of OAuth credentials from the Magento Admin, redirecting URL for third-party integrations, and identifying the available API resources that are needed for the integration.
Let follow the instructions below to understand specifically what you should do to create the great API integration for your own store.

Add a new integration:

• On the Admin panel, click System. In the Extensions section, select Integrations.
• In the upper-right corner, click the Add New Integration button and complete all information
  
• In the ` Integration Info` section, do the following

• In the Name field, enter the name of the integration
• In the Email field, enter the contact email address
• In the Callback URL field, enter the Callback URL where OAuth credentials can be sent when using OAuth for token exchange. We strongly recommend using https://.
