Correct Answers: A, C and E

A custom connector is an API wrapper around the 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, you need to describe the API's operations before you can export your application's APIs.

There are three approaches to how to create the API definitions: Using a blank custom connector.

Using an Open API definition.

Using a Postman Collection.

Then you need to secure your Web APIs and set the authentication type for your custom connector.

In the end, when you test a new custom connector, you can use it in Poser Apps, Power Automate, and Azure Logic Apps.

All other options are incorrect.

To create a custom connector for consuming the Azure Web App REST API in Power Apps, you will need to define an API definition that describes the methods, parameters, and responses that the API supports. There are different tools available to create an API definition, and you will need to choose the most suitable one based on your needs and expertise.

Here are the tools you can consider:

A. OpenAPI: OpenAPI (formerly known as Swagger) is a widely used specification for describing REST APIs. You can use the OpenAPI Designer tool to create an API definition in YAML or JSON format, and then import it into Power Apps as a custom connector.

B. Web API: Web API is a framework for building HTTP-based services using .NET. You can use Web API to create a RESTful API and then use the Swashbuckle library to generate an OpenAPI specification for it.

C. Blank custom connector: If you prefer to create the API definition directly in Power Apps, you can start with a blank custom connector and define the API methods, parameters, and responses using the connector editor.

D. PCF Component: PCF (PowerApps Component Framework) is a framework for building custom components for Power Apps. While it is not specifically designed for creating API definitions, you can use it to create a component that defines the API methods and parameters and then use that component in a custom connector.

E. Postman Collection: Postman is a popular tool for testing and documenting APIs. You can use Postman to define the API methods, parameters, and responses and then export them as an OpenAPI specification or a custom connector definition.

F. Organization service: The Organization service is a web service provided by Dynamics 365 that enables you to interact with the Dynamics 365 data and metadata using a REST API. While it is not specifically designed for creating API definitions, you can use it to create a custom connector that exposes the Dynamics 365 data and metadata as an API.

In summary, to create an API definition for consuming the Azure Web App REST API in Power Apps, you can use OpenAPI, Web API, a blank custom connector, PCF Component, Postman Collection, or the Organization service. You will need to evaluate the pros and cons of each option based on your requirements and expertise.
