Wait workflow state - AWS Step Functions
Wait State Examples

Wait workflow state

A Wait state ("Type": "Wait") delays the state machine from continuing for a specified time. You can choose either a relative time, specified in seconds from when the state begins, or an absolute end time, specified as a timestamp.

In addition to the common state fields, Wait states have one of the following fields.

Seconds

A time, in seconds, to wait before beginning the state specified in the Next field. You must specify time as a positive, integer value from 0 up to 99999999.

Timestamp

An absolute time to wait until beginning the state specified in the Next field.

Timestamps must conform to the RFC3339 profile of ISO 8601, with the further restrictions that an uppercase T must separate the date and time portions, and an uppercase Z must denote that a numeric time zone offset is not present, for example, 2024-08-18T17:33:00Z.

Note

Currently, if you specify the wait time as a timestamp, Step Functions considers the time value up to seconds and truncates milliseconds.

SecondsPath

A time, in seconds, to wait before beginning the state specified in the Next field, specified using a path from the state's input data.

You must specify an integer value for this field.

TimestampPath

An absolute time to wait until beginning the state specified in the Next field, specified using a path from the state's input data.

Note

You must specify exactly one of Seconds, Timestamp, SecondsPath, or TimestampPath. In addition, the maximum wait time that you can specify for Standard Workflows and Express workflows is one year and five minutes respectively.

Wait State Examples

The following Wait state introduces a 10-second delay into a state machine.

"wait_ten_seconds": {
  "Type": "Wait",
  "Seconds": 10,
  "Next": "NextState"
}

In the next example, the Wait state waits until an absolute time: March 14, 2024, at 1:59 AM UTC.

"wait_until" : {
  "Type": "Wait",
  "Timestamp": "2024-03-14T01:59:00Z",
  "Next": "NextState"
}

You don't have to hard-code the wait duration. For example, given the following input data:

{
  "expirydate": "2024-03-14T01:59:00Z"
}

You can select the value of "expirydate" from the input using a reference path to select it from the input data.

"wait_until" : {
    "Type": "Wait",
    "TimestampPath": "$.expirydate",
    "Next": "NextState"
}
