Field Name | Type | Description
---|:---:|---
action | `"send"` | `"receive"` | **Required**. 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).
-channel | [Reference Object](#referenceObject) | **Required**. A `$ref` pointer to the definition of the channel in which this operation is performed. If the operation is located in the [root Channels Object](#channelsObject), it MUST point to a channel definition located in the [root Channels Object](#channelsObject), and MUST NOT point to a channel definition located in the [Components Object](#componentsObject). If the operation is located in the [Components Object](#componentsObject), it MAY additionally point to a channel definition located in the [Components Object](#componentsObject). 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.
