# Loop Breakpoint

> Control loop execution with breakpoints for testing and debugging

The Loop Breakpoint block allows you to control and test loops within your automation. Use it to prevent excessive iterations during debugging or to validate loop behavior.

## Inputs

### ☐ Loop Reference *(Required)*

Select which loop in your automation this breakpoint will control.

<Note type="success">
  **Example:** Select the product scraping loop to test product data extraction
</Note>

### ☐ Stop Loop *(Required)*

Choose whether to halt the loop after one iteration:

* **Unchecked (Default):** Loop runs fully as intended
* **Checked:** Loop executes only once for testing

## Usage Examples

  <Card title="1. Testing Product Scraper" icon="bug">
    <div className="flex flex-col space-y-2">
      <div className="flex items-center gap-2 text-sm">
        <span className="px-2 py-1 bg-purple-100 rounded-md">Loop</span>
        <span className="font-mono bg-slate-100 px-2 py-1 rounded">Product List Loop</span>
      </div>

      <div className="flex items-center gap-2 text-sm">
        <span className="px-2 py-1 bg-purple-100 rounded-md">Stop Loop</span>
        <span className="text-green-600">✓ Enabled</span>
      </div>
    </div>

    <Note className="mt-2">Tests extraction of first product before running full loop</Note>
  </Card>

  <Card title="2. Production Email Sender" icon="envelope">
    <div className="flex flex-col space-y-2">
      <div className="flex items-center gap-2 text-sm">
        <span className="px-2 py-1 bg-purple-100 rounded-md">Loop</span>
        <span className="font-mono bg-slate-100 px-2 py-1 rounded">Customer Email Loop</span>
      </div>

      <div className="flex items-center gap-2 text-sm">
        <span className="px-2 py-1 bg-purple-100 rounded-md">Stop Loop</span>
        <span className="text-red-600">✗ Disabled</span>
      </div>
    </div>

    <Note className="mt-2">Processes all customer emails in production</Note>
  </Card>
</CardGroup>

## When to Use

<CardGroup cols={2}>
  <Card title="Debugging" icon="bug">
    * Enable Stop Loop during testing
    * Validates loop behavior quickly
    * Prevents unwanted iterations
  </Card>

  <Card title="Production" icon="rocket">
    * Disable Stop Loop for full execution
    * Processes all iterations as intended
    * Normal automation operation
  </Card>
</CardGroup>

## Notes

<Warning>
  * Always test loops with Stop Loop enabled first
  * Remember to disable Stop Loop before deploying to production
  * Useful for validating complex loop logic
