Instant Commerce

Instant Commerce is a storefront builder for headless commerce that enables eCommerce brands to build superior online shopping experiences, fast and easy, with best-in-class technology.

The wonderful folks at Instant Commerce provide a simple integration for Faslet, the only thing needed is your unique Faslet Shop ID.


In order to provide full insights, Faslet requests that you implement both the Size Me Up Virtual Assistant on the Product Page and Order Tracking on the Thank You page. To validate your installation, please see our Integration Checklist

Integration Guide

Size Me Up Virtual Assistant

In the Instant Commerce admin panel, go to integrations, and find the Faslet button.

Faslet Instant Commerce integration

Click enable, you should now see the following screen:

Faslet Instant Commerce integration

Here you can fill in your Faslet Shop ID, and the name of the option for sizes from Shopify.

The size option can be found in your Shopify Admin panel, when editing a product. For example, if you see this:

Shopify size name

then the size option is "Size".

If in doubt, please reach out to the Faslet Support.

That's it! The Size Me Up Virtual Assistant should now be integrated, and will be visible as products are activated in the Faslet system.

Order Tracking

This will allow Faslet to track orders and compare users that are using the Faslet Size Me Up Virtual Assistant with users that are not using the Virtual Assistant.

SHOP_ID should be the shop identifier provided by Faslet for your store

If you'd like Faslet to help you install the order tracking code, Shopify allows for adding Collaborators (see article for more details). Faslet will request the Themes and Manage Settings permissions. Note that "Only the store owner, or staff with Manage collaborator requests permission, can view collaborator access requests or grant collaborator access to a store."
