 The **Message TTL** is an optional field that allows you to set the time-to-live (TTL) for the correlated messages. TTL defines the time for which the message is buffered in Zeebe before being correlated to the process instance (if it can't be correlated immediately).
 The value is specified as an ISO 8601 duration. For example, `PT1H` sets the TTL to one hour. Learn more about the TTL concept in Zeebe in the [message correlation guide](../../../concepts/messages#message-buffering).

+You can send XML to the webhook or return XML using the response expression, but XML content is treated as a plain string. It will not be parsed or extracted into process variables.
