A Power Automate cloud flow needs to call an external API that requires an API key. The API key is stored in Azure Key Vault. The flow uses a service principal to authenticate to Key Vault. You need to retrieve the API key and use it in the HTTP request without exposing it in the flow's run history. What should you do?

Hard-code the API key in the HTTP action's header and mark the action as 'Secure inputs'.

Store the API key as a plain text value in a flow variable and use it in the HTTP action.

Use the 'HTTP with Azure AD' action and select the service principal as the authentication type.

Use the 'Get secret' action from the Azure Key Vault connector, then reference the secret in the HTTP action's header with 'Secure inputs' enabled.
