Integration

Catalogian + n8n

n8n is an open-source, self-hostable workflow automation platform with 400+ integrations. For teams that need full control over their automation infrastructure, connecting Catalogian's webhooks to n8n gives you product feed change automation without sending data through third-party SaaS platforms.

When Catalogian detects changes in your product feed, it posts structured change data to n8n's webhook node. From there, n8n's workflow editor lets you process, filter, and route the data — update databases, trigger scripts, send notifications, or call external APIs. Because n8n is self-hosted, your product data never leaves your infrastructure.

n8n's code node support means you can write custom JavaScript or Python to process Catalogian's change data within your workflows. Parse specific field changes, calculate percentage differences, or transform the data for downstream systems — with the full flexibility of code inside a visual workflow builder.

How it works

Set up an n8n webhook node

In n8n, create a new workflow with a Webhook trigger node. Set the HTTP method to POST and copy the webhook URL.

Register with Catalogian

Add n8n's webhook URL as an endpoint for your Catalogian source. Catalogian will POST change data to your self-hosted n8n instance on every feed update.

Build self-hosted automation

Use n8n's 400+ nodes to route change data. Add code nodes for custom processing. Your product data stays on your infrastructure throughout the entire workflow.

curl -X POST "https://catalogian.com/v1/sources/src_abc/webhooks" \
  -H "Authorization: Bearer cat_sk_live_..." \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://n8n.your-domain.com/webhook/catalogian-changes",
    "events": ["delta.completed"],
    "secret": "whsec_your_signing_secret"
  }'

# n8n receives the webhook, verifies the signature,
# and runs your self-hosted workflow pipeline

Frequently asked questions

Can I self-host both n8n and use Catalogian?

Yes. n8n runs on your infrastructure, and Catalogian sends webhooks to your n8n instance's URL. Your product change data flows directly from Catalogian's servers to your self-hosted n8n — no third-party intermediary.

Does n8n support Catalogian's webhook signature verification?

Yes. Use n8n's code node to verify the HMAC-SHA256 signature in the webhook header against your signing secret before processing the payload.

Can I use n8n's code nodes to process Catalogian data?

Yes. n8n supports JavaScript and Python code nodes. You can parse Catalogian's change payload, filter for specific field changes, calculate aggregations, or transform the data for downstream systems.
