## Zapier vs custom webhooks

Each runs in two directions. hyzl names the four cards on the Integrations page after those directions.

| ------------------------- | ---------------------------------- | ----------------------------- |
| **Setup**                 | No-code, visual editor             | Requires a server / endpoint  |
| **Best for**              | Non-developers, quick integrations | Developers, custom systems    |

Use **Zapier** if you want to connect hyzl to apps like HubSpot, Google Sheets, Asana, or Slack without writing code. Use **custom webhooks** if you are building a custom integration or need full control over the data flow.
