Use `send` when it's expected that the application will send a message to the given [`channel`](#operationObjectChannel), and `receive` when the application should expect receiving messages from the given [`channel`](#operationObjectChannel).

Please note the `channel` property value MUST be a [Reference Object](#referenceObject) and, therefore, MUST NOT contain a [Channel Object](#channelObject). However, it is RECOMMENDED that parsers (or other software) dereference this property for a better development experience.

 <a name="operationObjectSecurity"></a>security | [[Security Requirement Object](#securityRequirementObject)]| A declaration of which security mechanisms are associated with this operation.
