You can pause an Airflow DAG for human approval by using deferrable human-in-the-loop operators like ApprovalOperator. These operators suspend DAG execution until an approval response is submitted via the Web UI or REST API, then resume the workflow automatically.

A human-in-the-loop workflow in Airflow pauses automated DAG execution to require human decision gates, form inputs, or dynamic branching. You need it when downstream tasks depend on manual approvals, data entry, or human-driven task selection.

Yes, you can create form-driven dynamic branching in Airflow using the HITLBranchOperator. It pauses the DAG to collect human input and uses that response to determine which downstream tasks run or skip, enabling guided workflow orchestration.

Yes, this approach uses deferrable HITL operators designed specifically for Airflow 3.1+ environments. Deferrable operators free up worker slots while the DAG waits for human input through the Web UI or REST API.

You collect form data during an Airflow DAG run by using the HITLOperator or HITLEntryOperator to pause execution. Users submit form inputs through the integrated Web UI or REST API, and the DAG continues using the collected data.

The best way to add manual decision gates to an Airflow workflow is using deferrable HITL operators. They integrate with the Web UI and REST API to pause DAGs, capture human responses, and trigger notifiers for guided workflow orchestration without holding worker resources.
