Request Syntax

PUT /things/thingName/jobs/$next?namespaceId=namespaceId HTTP/1.1 Content-type: application/json { "statusDetails": { "string" : "string" }, "stepTimeoutInMinutes": number }

URI Request Parameters

The request uses the following URI parameters.


The namespace used to indicate that a job is a customer-managed job.

When you specify a value for this parameter, Amazon IoT Core sends jobs notifications to MQTT topics that contain the value in the following format.



The namespaceId feature is only supported by Amazon IoT Greengrass at this time. For more information, see Setting up Amazon IoT Greengrass core devices.

The name of the thing associated with the device.

Length Constraints: Minimum length of 1. Maximum length of 128.

Request Body

The request accepts the following data in JSON format.


A collection of name/value pairs that describe the status of the job execution. If not specified, the statusDetails are unchanged.

The maximum length of the value in the name/value pair is 1,024 characters.

Specifies the amount of time this device has to finish execution of this job. If the job execution status is not set to a terminal state before this timer expires, or before the timer is reset (by calling UpdateJobExecution, setting the status to IN_PROGRESS, and specifying a new timeout value in field stepTimeoutInMinutes) the job execution status will be automatically set to TIMED_OUT. Note that setting the step timeout has no effect on the in progress timeout that may have been specified when the job was created (CreateJob using field timeoutConfig).

Valid values for this parameter range from 1 to 10080 (1 minute to 7 days).

Type: Long

Required: No
