 Name::      The name of the connector.
-URL::       The request URL. If you are using the <<action-settings, `xpack.actions.allowedHosts`>> setting, make sure the hostname is added to the allowed hosts.
-Method::    HTTP request method, either `post`(default) or `put`.
-Headers::   A set of key-value pairs sent as headers with the request
-Require authentication:: If true, a username and password for login type authentication must be provided.
-Username::      Username for HTTP basic authentication.

+Authentication::
+The authentication type: none, basic, or SSL.
+If you choose basic authentication, you must provide a user name and password.
+If you choose SSL authentication, you must provide SSL server certificate authentication data in a CRT and key file format or a PFX file format. You can also optionally provide a passphrase if the files are password-protected.
+HTTP headers::   A set of key-value pairs sent as headers with the request.
+Certificate authority::
+A certificate authority (CA) that the connector can trust, for example to sign and validate server certificates.
+This option is available for all authentication types.
+CA file:::
+The certificate authority file.
+Verification mode:::
+Controls the certificate verification.
