module [Addon] StripePaymentLinks → Mailchimp Sync

[Mikel]

Hi, everyone! We recently built a small add-on module for our StripePaymentLinks setup and thought it might be useful to share here.

We’ve been working with StripePaymentLinks quite a lot lately, and one thing the clients always wanted was a simple way to get purchases synced into Mailchimp without relying on external paid add-ons. So we built a small ProcessWire module to handle exactly that.

The idea is simple: every time a customer makes a purchase via StripePaymentLinks, their details (name, email) plus the purchased products (as tags) get synced directly into Mailchimp. That means you can instantly segment, automate, and follow up with buyers without any manual exports.

We built this because we didn’t want to rely on a separate paid Stripe → Mailchimp connector. With this add-on, it’s all handled natively inside ProcessWire — lightweight, minimal, and no extra subscription fees.

What it does right now:

• Hooks into the creation of purchase repeater items (repeater_spl_purchases)

• Pulls customer name + email from the User created by StripePaymentLinks

• Extracts product names either from the expanded Stripe session line_items or as fallback from the purchase_lines field

• Pushes everything to Mailchimp, creating the subscriber if you allow it in the config

• Assigns the product titles as Mailchimp tags

Config is super simple: just drop in your Mailchimp API key, Audience ID, and decide if you want to auto-create subscribers or only update existing ones.

We’re keeping this intentionally minimal — one module, no extra steps, no fuss. Install, configure, and you’re done.

We’ve been running it in production for some clients and it’s working reliably. If you’re already using StripePaymentLinks, this could save you the cost of external integrations while keeping everything in one place.

Happy to hear your feedback or ideas for tweaks.
