To use this app, you will need to be on the Shopify Plus plan and have upgraded to Checkout Extensibility.
Shopify's Checkout Extensibility upgrade guide provides more details on upgrading if needed.
You will also need access to your Experian Address Validation API authentication token, which can be generated on our Self Service Portal. This guide assumes that you already have access to our Self Service Portal via either a free trial or as a new or existing customer. If you do not have an account yet, please get in touch with your account manager or contact one of our regional sales teams.
