Or create this via the Azure Portal:

This provides a simple way to proxy API requests via your domain to a third party API while keeping your API credentials hidden. This approach is also highly performant and cost effective thanks to the serverless approach.

Simply update the Backend URL with your desired destination API. Update the request params for authentication or add the necessary header override.
