Latenode

Sync new BoomTown leads to targeted Mailchimp audiences

This template runs on a schedule, calls the BoomTown API from JavaScript for new leads, and adds or updates each person in Mailchimp.

Email, name, and lead tags come from BoomTown. Mailchimp matches on email so a repeat lead refreshes the same subscriber. Connect Mailchimp. Put the BoomTown API key in that JavaScript node and the Mailchimp API key on the Mailchimp connection.

How Latenode estimates time and cost

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.
