3. Build a Background Check application with Temporal and Python

   • Source code
   • Tutorial
   • Instructions:

     # Prerequisites

     $ temporal operator namespace create background_check_namespace
     $ python -m worker.main
     
     # Run tests
     $ pytest
     
     # Run workflow
     $ temporal workflow start \
         --workflow-id background_check_workflow \  # Manually set Workflow ID
         --task-queue background_check_task_queue \
         --type BackgroundCheck \
         --input '"555-55-5555"' \
         --namespace background_check_namespace
     
     # List workflow executions
     $ temporal workflow list \
         --namespace background_check_namespace
     
     # Save workflow execution data to file
     $ temporal workflow show \
         --workflow-id background_check_workflow \
         --namespace background_check_namespace \
         --output json > tests/background_check_workflow_history.json
