Business API Authentication

How would I go about using this to implement the preliminary endpoint verification process before you set up the hooks? Rather, is it possible?

For verification, you will need to setup your callback URL to receive a get request from Meta and add your random string to verify the token. The verify token you set in meta must match with the verify token you set in the code and return a successful response to register your webhook.

[HttpGet]
        public ActionResult<string> ConfigureWhatsAppMessageWebhook([FromQuery(Name = "hub.mode")] string hubMode,
                                                                    [FromQuery(Name = "hub.challenge")] int hubChallenge,
                                                                    [FromQuery(Name = "hub.verify_token")] string hubVerifyToken)
        {
            _logger.LogInformation("Results Returned from WhatsApp Server\n");
            _logger.LogInformation($"hub_mode={hubMode}\n");
            _logger.LogInformation($"hub_challenge={hubChallenge}\n");
            _logger.LogInformation($"hub_verify_token={hubVerifyToken}\n");

            if (!hubVerifyToken.Equals(VerifyToken))
            {
                return Forbid("VerifyToken doesn't match");
            }
            return Ok(hubChallenge);
        }
