Estimating Monthly Car Loan Payments in Power Apps and Power Automate

Correct Answer: B

Power Platform provides 300+ connectors.

If you need to communicate with services that Microsoft doesn't have on its list of connectors, you can create your custom connector.

A custom connector is an API wrapper around your REST API.

You can create such a wrapper for Azure Functions, Azure Web Apps, Azure API apps.

When you create your application using one of these services, before you can export your application's APIs, you need to describe the API's operations by creating API definitions.

Power Apps or Power Automate portals provide a wizard-type interface for creating a custom connector (Number 1)

You need to input the connector name, select the security, and set the authentication type for your custom connector.

There are four types of API authentication you can choose from (Number 2)

Then you provide the API definition.

After the custom connector's successful test, you push the "Create connector" button (Number 3)

And you can use your new custom connector in Power Apps, Power Automate, and Azure Logic Apps.

Options A, C, and D are incorrect because you don't need to create a Dataverse plug-in, Web API, or PCF component to connect to the external application.

You need to create a custom connector.

The best approach to integrate the Azure Function that estimates monthly car loan payments into Power Apps and Power Automate is to create a Custom Connector.

A Custom Connector is a proxy or wrapper around an API that allows you to integrate external services into Power Apps and Power Automate. Custom connectors provide a simplified interface to access and interact with external services and expose the API operations as a set of actions and triggers.

To create a Custom Connector for the Azure Function, you need to follow these steps:

1. Create a new Custom Connector by going to the Power Apps or Power Automate portal, selecting the "Custom connectors" option from the left-hand menu, and clicking the "New custom connector" button.

2. Enter a name for the connector, and then provide the connection details for the Azure Function. This will include the base URL for the Azure Function, any authentication details, and any headers or query parameters that need to be passed.

3. Define the actions that will be available through the Custom Connector. In this case, you would define an action that accepts the three parameters required by the Azure Function: total loan amount, loan term (in months), and interest rate.

4. Map the inputs and outputs of the action to the parameters and return values of the Azure Function.

5. Test the Custom Connector by using it in a Power App or Power Automate flow.

Note that creating a Dataverse plug-in or a Dataverse Web API would not be the best approach for integrating the Azure Function into Power Apps and Power Automate, as these options are more suited for integrating with the Dataverse data model. PCF components, on the other hand, can be used to create custom controls and visualizations in Power Apps, but are not directly related to integrating with external services.
