# Action
> Perform actions in connected applications like creating tasks, sending messages, or updating records.
## Overview
The Action node executes operations in your connected integrations - send Slack messages, create CRM records, add rows to spreadsheets, update project tasks, and more.
**Best for**: Creating/updating records, sending messages, triggering actions
in connected apps, and integrating with external services.
## Configuration
1. **Select Integration**: Choose from connected apps (Slack, Google Sheets, Notion, etc.)
2. **Choose Action**: Select a specific action (Send message, Create record, etc.). The available fields depend on your selection.
3. **Select Connection**: If you have multiple connections, choose which one to use
4. **Map Fields**: Provide data from previous nodes using variables. Hover a field label to view its description when guidance is available.
5. **Configure Settings**: Action-specific options
### Field Configuration Modes
Each field in an action can be configured independently with one of these modes:
| Mode | Description | When to Use |
| ------------- | ----------------------------------------------------------- | -------------------------------------------- |
| **Manual** | Enter a static value or use variables from previous nodes | When you know exactly what value to use |
| **Auto** | AI automatically determines the best value based on context | When the value depends on workflow context |
| **Prompt AI** | Provide instructions for AI to generate the value | When you need custom AI logic for this field |
| **None** | Skip an optional field entirely | When the action does not need that input |
Recipient fields such as To, Cc, and Bcc are never filled by AI by default. If you switch them to Auto or Prompt AI, the editor shows a warning, because earlier steps can contain untrusted text from form submissions or meeting invites. At runtime, AI-generated addresses are validated against recipient data from previous nodes; if an address cannot be verified, the step fails instead of sending.
**Manual Mode Example:**
```handlebars theme={null}
{{trigger.output.customer_email}}
```
**Prompt AI Mode Example:**
```text theme={null}
Based on the sentiment analysis result {{agent.output.structured.sentiment}},
write an appropriate subject line for the follow-up email.
```
### Connection Selection
If you have multiple connections to the same integration (e.g., multiple Slack workspaces or Gmail accounts), select which connection this action should use. This is configured at the action level.
If the selected connection is expired or missing scopes required by this action, the connection selector shows a warning with a link to reauthorize.
### Requires Confirmation
When enabled, the workflow will pause before executing this action and request user confirmation. This is useful for:
* Actions with significant external impact (sending emails, creating records)
* Review steps before data is pushed to external systems
* Compliance workflows requiring human approval
**Default:** Disabled (action executes automatically)
### Error Handling
Configure how errors are handled:
| Strategy | Behavior |
| ------------------ | ----------------------------------- |
| **Stop** (default) | Workflow stops immediately on error |
| **Callback** | Route to an error handling branch |
| **Continue** | Continue with error data available |
