Wait task definition object

A Wait task (identified by "type": "Wait") causes the system to delay the process from continuing for a specified time. The time can be specified as a wait duration, specified in seconds, or an absolute expiry time, specified as an ISO-8601 extended offset date-time format string.

For example, the following Wait task introduces a ten-second delay into a process:

"Wait Ten Seconds" : {
  "type": "Wait",
  "seconds": 10,
  "nextTask": "Next Task"
}

This waits until an absolute time:

"Wait Until" : {
  "type": "Wait",
  "timestamp": "2016-03-14T01:59:00Z",
  "nextTask": "Next Task"
}

The wait duration does not need to be hardcoded. Here is the same example, reworked to look up the timestamp time using a JSONPath expression tothe data, which might look like { "expiryDate": "2016-03-14T01:59:00Z" }:

"Wait Until" : {
  "type": "Wait",
  "timestampExpression": "${expiryDate}",
  "nextTask": "Next Task"
}

The Wait task has following additional fields:

The JSONPath expression must be inside a placeholder ${ }. To escape the expression, prefix it with an extra $ character, e.g. $${ }. See JSONPath for more information about JSONPath.

JSONata expression can also be used instead of JSONPath, prefix the expression with jsonata, e.g. ${jsonata: }. See JSONata for more information about JSONata.

To reference workflow input, use ${workflow.input}.

To reference task input and output, use ${<TASK_NAME>.input} and ${<TASK_NAME>.output} respectively.

Here are more examples of acceptable expressions:

• ${workflow.input.waitSeconds}

• ${TaskName.input.waitSeconds}

• ${['Task Name'].output.waitSeconds}

• ${jsonata:$now()}
