# Zapier & Webhooks

Threadly supports bidirectional automation via Zapier and raw HTTP webhooks, letting you connect to thousands of external apps without code.

Requires **Premium**. The Zapier integration also requires a feature flag — contact <support@trythreadly.com> to enable it.

***

## Inbound webhooks — trigger Threadly from external systems

Every Threadly workflow with the **Threadly Inbound Webhook** trigger exposes a unique URL. POST to that URL to fire the workflow from any external system.

### Setup

1. Create a [Workflow](/threadly/workflows/creating-your-first-workflow.md) and select **Threadly Inbound Webhook** as the trigger.
2. Copy the webhook URL shown in the trigger settings.
3. Configure your external system to POST to that URL.

### Passing data in the request body

Include a JSON body to pass dynamic values into the workflow:

```json
{
  "channel_id": "C012AB3CD",
  "user_id": "U098GHI765",
  "variables": {
    "customer_name": "Acme Corp",
    "renewal_date": "2026-06-01"
  }
}
```

These values are available as template variables in your workflow steps.

***

## Outbound webhooks — send data to external systems

Use the **Send a Webhook** step inside a Workflow to POST data outbound when something happens in Threadly.

**Example:** A user submits a Threadly form → a workflow fires → Threadly POSTs the form data to your internal API or CRM.

See [Workflow Steps](/threadly/workflows/workflow-steps.md) for full configuration details.

## Zapier integration

### Trigger Threadly from a Zap

1. In Zapier, set up any trigger app (e.g. "New row in Google Sheets").
2. Add a **Webhooks by Zapier** action step.
3. Paste the Threadly inbound webhook URL as the POST destination.
4. Map the fields you want to send.

### Trigger a Zap from Threadly

1. In Zapier, create a new Zap with **Webhooks by Zapier** as the trigger (Catch Hook).
2. Copy the Zapier-generated webhook URL.
3. In Threadly, add a **Send to Zapier** step in your workflow.
4. Paste the Zapier URL in the step configuration.

When the Threadly workflow runs, it fires the Zapier hook and kicks off the rest of your Zap.
