└─────────── Minute (0-59)

​
Initial Context Template

The initial_context_template object allows you to pass variables to your webhook or workflow that can be accessed using {{ initial.key }} syntax:
  • In request body: {{ initial.key }} will be replaced with the value
  • In headers: {{ initial.key }} can be used in header values
  • In query params: {{ initial.key }} can be used in query parameters
  • In path: {{ initial.key }} can be used in URL paths
You can also combine with:
  • System secrets: {{ #secret_key }} for vault secrets
  • Workflow step responses: {{ step.response.variable }} in workflows

​
Use Cases

  • Daily Reports: Generate reports every day at 9 AM
  • Weekly Maintenance: Run maintenance tasks every Sunday at 2 AM
  • Monthly Billing: Process billing on the 1st of every month
  • Business Hours: Execute during business hours only (with rules)
  • Complex Patterns: Create sophisticated scheduling patterns
