Environment

SOI 4.2

Resolution

SOI 4.2 REST API works with secure protocol.

Note: By default, the non-secure interface is not allowed with the Basic authentication (user name and password), where the user name and password are sent as a plain text ( Base64 encoded). If you want to allow Basic authentication over the non-secure connection, you can configure the web.xml file.

You can always use the non-secure interface with other types of authentications: CA EEM token and JSESSION. However, you can use the secure interface with all three types of authentications: Basic (user name and password), CA EEM token, and JSESSION. For more information about these authentication methods, see the REST Web Services Authentication.

Refer following wiki page for more details about this.

1) You may change this and allow basic authentication over non-secure (http), then update "\SOI\SamUI\webapps\rest\WEB-INF\web.xml" as mentioned below. 
 allowPlainCredentials false
 Change the value from "false" to "true" and restart 'CA SOI UI Service' services

2) Now, access REST API with http http://<servername>:7070/rest/alert/4503599635341545/action
