We recommend installing our plugin via both the Script Manager and Site Verification Tags.

Script Manager is the official method to customise your checkout. This allows address validation on your checkout and will be supported by BigCommerce indefinitely.

The Site Verification Tag install will provide further address validation on your account registration and user address book pages. This is currently the only way to add global scripts to your BigCommerce site.

Script Setup

In the Script Manager and Verification Tag install you will the script below with some amendments.

window.idpcConfig = {
apiKey: "Your API Key goes here"


You will need to replace apiKey attribute in the first script tag. This should be replaced with the Key on your account

Add to Site Verification Tags

  1. Navigate to your Tracking Code page by clicking on the Advanced Settings tab from your dashboard.

  2. Check the Site Verification Tags checkbox in the Analytics page (under the General Settings tab).

This integration will be continually updated without your action. However there will be occassion when a backwards breaking change is introduced. When this happens we will increment the version number at the end of the script src.

Version Pinning

It's possible to fix the version number of the integration script. The version suffix @VERSION in src can be replaced with a specific version number. Versions are automatically logged and tracked on our Changelog.

Admin Pages
