Endpoint Properties

Name	Type	Required	Default	Description
`name`	string	✓		The logical name
`body`	string			The data to use as message body. You can externalize the data by using file: or classpath: as prefix and specify the location of the file.
`headers`	object			The data to use as message headers as key=value pairs. You can externalize the data by using file: or classpath: as prefix and specify the location of the file. This is a multi-value option with prefix: header.
`bridgeErrorHandler`	boolean		`false`	Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions (if possible) occurred while the Camel consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. Important: This is only possible if the 3rd party component allows Camel to be alerted if an exception was thrown. Some components handle this internally only, and therefore bridgeErrorHandler is not possible. In other situations we may improve the Camel component to hook into the 3rd party component and make this possible for future releases. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.
`exceptionHandler`	object			To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.
`exchangePattern`	enum			Sets the exchange pattern when the consumer creates an exchange.
`delay`	integer		`1000`	The number of milliseconds to wait before triggering. The default value is 1000.
`exchangeProperties`	object			The data to use as exchange properties as key=value pairs. You can externalize the data by using file: or classpath: as prefix and specify the location of the file. This is a multi-value option with prefix: exchangeProperty.
`variables`	object			The data to use as exchange variables as key=value pairs. You can externalize the data by using file: or classpath: as prefix and specify the location of the file. This is a multi-value option with prefix: variable.
