HTTP methods

The HTTP methods of the REST API provide the operations available on Rule Execution Server artifacts, such as create, read, update, and delete.

The following HTTP methods are supported:

Table 1. Supported HTTP methods
HTTP method	Description
POST	Creates a resource.
GET	Retrieves a resource.
PUT	Updates an existing resource. Does not create the resource if it does not exist.
DELETE	Deletes a resource.

Security

When using HTTP methods, consider the security aspects. For tighter security, some firewalls do not allow HTTP PUT or DELETE traffic. To accommodate this restriction, you can send these requests in two ways:

Use the X-Method-Override or X-HTTP-Method-Override HTTP header fields to channel a PUT or DELETE request through a POST request.
Use the x-method-override or the x-http-method-override URI parameters.
For example: POST /api/v1/ruleapps?...&x-method-override=PUT
