Updated at October 14, 2025

An execution contains all information about a particular workflow run. Possible execution statuses: In queue, In progress, Paused, Canceled, Error, and Executed. Learn more about possible error codes.

You can execute a workflow using:

Management console, the CLI, and the API. For more information, see Starting a workflow.
Yandex EventRouter. To do this, you need to specify the workflow as a target in a rule. To learn more about how to create a rule, see Creating a rule with a Yandex Workflows target. The rule defines the events that should trigger a workflow. The event body is provided to the execution as an input parameter.
Timer. The schedule is set in cron expression format. For more information, see Scheduling a workflow to start on a timer.

Possible error codes

Error	Description
`ALL`	Error you can specify in a retry policy for the policy to apply to any error type other than `STEP_INTERNAL`.
`STEP_DATA_LIMIT_EXCEEDED`	Input or output data limit exceeded. For more information, see Quotas and limits in Serverless Integrations.
`STEP_NO_CHOICE_MATCHED`	There is no suitable execution path in `choices`. For more information, see Switch.
`STEP_PERMISSION_DENIED`	No access to resource.
`STEP_TIMEOUT`	Step timeout exceeded. For more information, see Quotas and limits in Serverless Integrations.
`STEP_INVALID_OUTPUT`	Invalid output data.
`STEP_INTERNAL`	Internal error. If a step terminates with this error, you cannot apply the retry policy, and the execution immediately gets the `Error` status.
`STEP_INVALID_TEMPLATE_EXPRESSION`	Invalid jq template.
`STEP_FAIL`	The execution ended with an error at the `Fail` step. For more information, see Fail.
`STEP_FAILED_PRECONDITION`	The resource state is invalid to complete the step, e.g., an email address is unverified or blocked.
`STEP_INVALID_ARGUMENT`	Invalid step parameters.
`STEP_QUOTA_EXCEEDED`	The resource request limit is reached.
