    • Subscribe to customers/create to capture account creation and send an event to Mixpanel.
    • No known webhook exists for customer login; an alternative approach was not provided.
    • Correlate the browser session and the webhook payload by sharing the customer ID across both contexts.

  • Status: Partial solution (account creation) identified; login tracking remains unresolved. No final decision or code shared; next steps are implementation and exploring a workaround for login events.

You can likely use the Mixpanel API, combined with Shopify webhooks.

For example, you can subscribe to customers/create and log events.

However, you’ll need a way to share the customer’s ID between the on-page session and the webhook.

Also, I’m not aware of a “customer login” webhook topic you can subscribe to.

But hopefully this information gets you started in the right direction.
