How it works

  1. 1
    Trigger
    Webhook / schedule / form submission fires the workflow.
  2. 2
    Validate & Enrich
    Inputs are sanitized; missing data is enriched via API lookups.
  3. 3
    AI Step
    GPT or Claude classifies, summarizes, or generates the next action.
  4. 4
    Branch & Route
    Conditional logic routes to the right downstream system.
  5. 5
    Write to Destination
    Final payload is delivered to CRM / DB / Slack / email.
  6. 6
    Observability
    Failures route to an alert channel with full payload context.
