Customer.io is a marketing automation platform. FluentCart processes an order is placed beautifully, but sending that data to external platforms needs an integration. AFI bridges that gap to Customer.io.

Why connect directly?

Cloud automation tools like Zapier charge per task and route your data through external servers. AFI processes everything on your WordPress site. No per-order fees, no external dependencies.

What you will need

  • A WordPress site with FluentCart installed and configured.
  • A Customer.io account.
  • The Advanced Form Integration plugin (free from WordPress.org).

Connect Customer.io to AFI

  1. Log in to your Customer.io account.
  2. Go to Settings → API Credentials and copy your Site ID and API Key.
  3. In WordPress, go to AFI → Settings → Customer.io.
  4. Enter the Site ID and API Key, then click Save Changes.

Setting up the integration

1. Create a new integration

Go to AFI → Add New. Name it FluentCart to Customer.io.

2. Pick your trigger

Select FluentCart as the form provider. AFI fires when an order is placed, giving you access to customer details, product information, and order totals.

3. Select Customer.io as the destination

Choose Customer.io from the platform dropdown and pick Add Customer. This creates or updates a customer in Customer.io.

4. Map fields

Match each Customer.io field on the left to the corresponding FluentCart field on the right. Common mappings include customer name, email, product details, and order total. You can also use smart tags like {{_submission_date}}.

5. Add conditions if needed

Only want to send certain orders? Set up a conditional rule based on any field value.

6. Save and test

Click Save Integration. Place a test order in your FluentCart store. Check Customer.io to confirm the data arrived. If anything looks wrong, open AFI → Log to see the exact request and response.

Free vs Pro

The free version maps email, name, and standard attributes to Customer.io with unlimited orders. Pro adds custom attributes and event tracking. No per-order fees on any plan.
