No authentication: This option is suitable if the web service or API you are calling does not require authentication.

Basic authentication: This option allows you to provide a username and password to authenticate the request. The username and password are included in the « Authorization » header of the HTTP request.

OAuth (The type we are using in our scenario): This option allows you to use OAuth 2.0 authentication to obtain an access token that can be used to authenticate the request. You will need to provide the OAuth 2.0 endpoint URL, client ID, client secret, and other relevant parameters.

Managed identity: This option allows you to use the managed identity of your Logic App to authenticate the request. This is useful if you want to grant your Logic App access to resources in Azure without having to store authentication credentials.
