Power Automate, formerly known as Microsoft Flow, is an integral part of Microsoft’s platform offering a range of workflow and automation capabilities. Power Automate helps to implement complex business logic that can be triggered directly from a canvas app, making automation more effortless and business operations seamless.
In preparing for the PL-400 Microsoft Power Platform Developer exam, you must understand how to utilize Power Automate to implement business logic from a canvas app. This article will walk you through the process and provide examples to ensure you thoroughly understand the concept.
Why Integrate Power Automate with Canvas App
The integration of Power Automate with Canvas Apps offers numerous benefits, including:
- Enabling users to create complex business logic without the need for code.
- You can initiate automation directly from the canvas app.
- Utilize built-in templates or create customized workflows suitable for your business.
- Improve efficiency and reduce time spent on repetitive tasks.
Utilizing Power Automate Cloud Flows
Power Automate Cloud Flows is a powerful tool that orchestrates across different services to perform business processes or tasks. To integrate this with a canvas app, you need to follow a few main steps:
Step 1: Creating a Cloud Flow in Power Automate
On the Power Automate homepage, click on ‘+ New flow’, then ‘Instant-from blank’. You can also create the flow directly from a canvas app by selecting Action => Power Automate from the canvas app platform.
Step 2: Setting up Flow Triggers
A flow’s first component is the trigger, the event that initiates the workflow. For instance, you can set a button in your Canvas app to trigger your Power Automate flow.
Step 3: Adding Actions to Your Flow
After setting up your trigger, you can add action steps. Each action step can be a different business process or operation. For example, an action step can be sending an email, creating a record, or updating an entity in the Common Data Service.
Step 4: Saving and Testing Your Flow
Once you’re done crafting your flow, save your work and test your flow. Note: ensure that you’ve set proper permissions for your flow to access the required resources.
Example: Sending an Email from a Canvas App
This example demonstrates how you can implement business logic from a canvas app using Power Automate Cloud Flows.
- In your canvas app, create a button and name it, for example, ‘Send Email’.
- Click on the button and in the OnSelect property, add the following formula: `PowerAppsbutton.Run(TextBox1.Text, TextBox2.Text)`, where TextBox1 and TextBox2 represent the input fields where the user inputs the email recipient and message.
- Go to Power Automate and create a new flow. In the flow creation menu, select ‘Instant—from blank’.
- Name your flow, e.g. ‘PowerApps button’, and choose PowerApps as the trigger.
- Click ‘New step’ and select the ‘Send an email’ action. In the ‘To’ field, click ‘Add dynamic content’ and select ‘Ask in PowerApps’. Repeat this step for the email body.
- Next, save your Cloud flow.
After completing these steps, every time a user inputs an email address and a message into TextBox1 and TextBox2, respectively, and clicks the ‘Send Email’ button, Power Automate will trigger a flow that sends an email to the specified recipient with the provided message.
Conclusion
Utilizing Power Automate Cloud Flows to implement business logic directly from canvas apps is an effective way to automate business operations. As you prepare for the PL-400 exam, understanding the concept and execution of this process is crucial. Microsoft Power Platform, including tools such as Power Automate and Canvas Apps, empowers developers to create robust solutions without significant coding effort. As a prospective PL-400 certified professional, mastering these tools will significantly enhance your problem-solving skills in the world of low-code development.
