About Using HTTP Methods
The HTTP protocol supports a number of methods that are used to specify the operation to be performed on a resource on the Web. Siebel CRM supports the HTTP GET and POST methods only. All other HTTP methods are blocked to maximize the security of your Siebel application. For information on using the HTTP GET and POST methods with Siebel CRM, see Transports and Interfaces: Siebel Enterprise Application Integration.
In Siebel CRM 8.1.1.14 and later releases, you can allow access to a blocked method for HTTP GET access using the GETEnabledMethods user property. For information about using the GETEnabledMethods user property, see Configuring Siebel Open UI.
