Working of Azure Logic Apps

Azure Logic Apps operate by orchestrating triggers and actions to create automated workflows. Let's illustrate this with an example:

Imagine a scenario where a company wants to streamline its customer onboarding process. Whenever a new customer submits a sign-up form on their website, the company needs to perform several tasks: send a welcome email, add the customer's information to a CRM database, and notify the sales team.

• Trigger:
  The Logic App in Azure is triggered when a new form submission is received on the company's website.
• Workflow Design:
  The Logic App designer connects the trigger to actions. First, an action sends a welcome email to the new customer. Next, another action inserts the customer's details into the CRM system. Lastly, a notification is sent to the sales team via a messaging platform.
• Execution:
  When a new form submission triggers the Logic App in Azure, it sequentially executes the defined actions. The welcome email is sent, the customer's data is added to the CRM, and the sales team is notified.
• Connectivity and Data Exchange:
  Logic Apps in Azure utilize connectors to interact with services. In this case, connectors link the Logic App to the company's email service, CRM system, and messaging platform.
• Dynamic Adaptation:
  If the customer's email address already exists in the CRM, the Logic App could be configured to take different actions, like sending a follow-up email instead.
• Completion and Reporting:
  After all actions are completed, the Logic App's workflow concludes, and the company can monitor the process through logs and reports.
