Using DialogFlow Rest API w/ API KEY

I’m having trouble using the DialogFlow REST API with the API key authentication method. When I use the following code:[YOUR_API_KEY]

I get the following response:

{ “error”: { “code”: 401, “message”: “Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See”, “status”: “UNAUTHENTICATED” } }

The error message suggests that you are missing the required authentication credential. You need to provide an OAuth 2 access token, login cookie, or other valid authentication credentials in the request. The API key authentication method is not sufficient for accessing the DialogFlow REST API.

You can refer to the documentation provided in the error message for more information on how to obtain the required authentication credentials.
