# Workflow actions

> Explore the actions available in Nedzo workflows, including voice calls, SMS, email, Slack messages, webhooks, contact updates, conditions, and wait steps.

Actions are the steps in your workflow that do something — make a call, send a message, update a contact, or call an external API. Add as many actions as you need, and they execute in order.

## Variables

Use `{{variable}}` syntax in any text field across all actions.

| Variable           | Description            |
| ------------------ | ---------------------- |
| `{{firstName}}`    | Contact's first name   |
| `{{lastName}}`     | Contact's last name    |
| `{{email}}`        | Contact's email        |
| `{{phone}}`        | Contact's phone number |
| `{{businessName}}` | Contact's company name |

Trigger data and previous step outputs are also available. For example, `{{nodeId.status}}` references the output of a previous action.

## Retries

All actions retry up to 3 times with exponential backoff on transient failures (network timeouts, rate limits). Permanent failures (invalid config, auth errors) fail immediately.
