This template receives contact JSON on a Latenode webhook, maps email, first name, and last name in JavaScript, then creates or updates the matching Constant Contact contact.
Point any system that can POST a contact at the webhook URL. Connect Constant Contact. Put the Constant Contact API key on the Constant Contact connection. Skip the write when the payload has no email.
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.

Add a Constant Contact connection and paste your Constant Contact API key there. Choose the list that should receive these contacts.
Map first name, last name, and email in JavaScript. Find the Constant Contact by email, then create or update. Send a test POST and confirm Constant Contact shows the person.
