Actions do the actual work in a workflow: API calls, transformations, notifications, flow control, and integrations. Use this action when your workflow needs to perform an operation, call an external service, or transform data for downstream nodes.

​
When To Use

  • Send branded email alerts through organization SMTP.
  • Deliver periodic PDF reports to distribution lists.

​
Configuration Checklist

  1. Configure SMTP server credentials and sender details.
  2. Set recipients, subject, and body with context variables.
  3. Send and inspect delivery response/errors.
  4. Add retries or fallback channels for critical alerts.

​
Inputs

  • Required node.data metadata: uiId, componentId, and operation (for actions that define an operation).
  • Action-specific configuration fields from the node editor.
  • Upstream context values from triggers or previous nodes (for example trigger.* or prior action outputs).

​
Outputs

  • Adds action result data to the workflow context for downstream nodes.
  • May produce external side effects (API updates, notifications, scripts, SSH commands, etc.).
  • Can emit structured values consumed by conditions or subsequent actions.

​
Failure Modes

  • Missing required configuration or invalid parameter values.
  • Missing/invalid context variable references from upstream nodes.
  • External dependency failures (HTTP errors, auth failures, timeouts, rate limits).
  • Payload validation/parsing errors during request or response handling.

​
Best Practices

  • Use secret storage for SMTP credentials.
