+	 * You can secure your webhook using a secret token or by using basic
+	 * authentication.
+	 *
+	 * **Secret token**: Use secret tokens to authenticate the payload and ensure
+	 * that contents are not tampered between Bitbucket and your endpoint.
+	 * Combined with HTTPS, it helps ensure the message transmitted is the one
+	 * that Bitbucket intended to send.
+	 *
+	 * When you define a secret for a webhook, each request is signed via a
+	 * Hash-based Message Authentication Code (HMAC). The default for this
+	 * algorithm is HMACSha256. The header X-Hub-Signature is defined and contains
+	 * the HMAC. For example, the header of the POST request would be plain text
+	 * encoded as follows:
+	 *
+	 * ```ini
+	 * x-hub-signature: sha256=c3383246d4fd871e66e962b50cc12222222222222222222222222222222222
+	 * ```
+	 *
+	 * To authenticate the validity of the message payload, the receiver can
+	 * perform the HMAC algorithm on the received body with the secret as the key
+	 * to the HMAC algorithm. If the results do not match, it may indicate there
+	 * was a problem with transmission that has caused the message payload to
+	 * change.
+	 *
+	 * **Basic authentication**: If your endpoint uses basic authentication (a
+	 * username and password), use this method to secure your webhook. When the
+	 * webhook data is sent, the authorisation header will be included  in the
+	 * HTTP request. The authentication credentials for the Authorization header
+	 * are base64 encoded.

+	 * @see https://confluence.atlassian.com/bitbucketserver/manage-webhooks-938025878.html#Managewebhooks-webhooksecrets */
