Latenode

Sync new Square customers to Constant Contact automatically

This template starts when Square sends a new-customer event, maps name and email in JavaScript, and creates a Constant Contact contact.

Connect Square and Constant Contact. Put Square access on the Square connection and the Constant Contact key on the Constant Contact connection. Filter the Square event so only new customers create contacts.

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.

How it works

1
Trigger

The scenario starts when Square sends an event to Latenode.

Logic

Keep new customers

JavaScript continues when the event is a new customer and maps name and email. Fetch the customer from Square if the payload is only an id.

3
Action

Create the Constant Contact

Constant Contact creates a contact from those mapped fields.
