This template receives data on a Latenode webhook, maps the payload in JavaScript, and creates a record in your Knack app.
JavaScript calls the Knack API with the object id and field values. Put the Knack API key in that JavaScript node. Paste the webhook URL into the system that sends events, then test with one payload.
Latenode bills workflow runtime in CPU seconds. The first 10,000 CPU seconds are free each month, then usage follows pay-as-you-go CPU-second pricing. Plug-and-Play (PnP) AI nodes are billed separately—each PnP token is $1 USD, charged pay-as-you-go at vendor cost plus a small processing fee, with no API keys required.

The scenario starts when an external system POSTs JSON to the Latenode webhook.
JavaScript reads the payload and builds the Knack field object for the record type you use.
JavaScript calls the Knack API to create the record. Put the Knack API key in that JavaScript node.
Add a webhook trigger and copy its URL into the external app that should send new records.
Add a JavaScript node and put your Knack API key there, with the application id and object id from Knack.
In that JavaScript node, map webhook fields onto Knack field keys and POST a create-record call. Send a test payload and open the new Knack row.
