The Manual Validation task allows you to pause a pipeline run within a stage, typically to perform some manual steps or actions, and then continue with the pipeline. For example, the user may need to manually validate certain deployment configurations before the pipeline starts a long running computational intensive job.

The Manual Validation task configuration includes an instructions parameter that can be used to provide related information, or to specify the manual steps the user should execute during the pause. You can configure the task to send email notifications to users and user groups when it is awaiting a review, and specify the automatic response (reject or resume) after a configurable timeout occurs.

You can specify the timeout value for the task using the timeoutInMinutes parameter available in control options. This parameter is optional.


For the task to run completely, the timeout value of the job should be higher than the timeout value of the task. See default job timeout values.


You can use variables to specify email addresses in the notifyUsers parameter.

When the Manual validation task is activated during a pipeline, it displays a message bar containing a link that opens the Manual validation dialog containing the instructions. After carrying out the manual steps, the administrator or user can choose to resume the run, or reject it. Users with 'Queue builds' permission on the pipeline can resume or reject the run.
