Latenode

Form to QR workflow

Inbound form JSON hits Mailhook; JavaScript calls Beaconstac’s REST API to create or update a dynamic QR asset; Google Sheets logs the mapping between submission id and QR link; Slack posts a short confirmation to your ops channel. Zapier is not part of the graph.

How Latenode estimates time and cost

Latenode bills workflow runs in credits: 1 credit = 30 seconds of processing. Minimum charge per run depends on your plan. 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.
