A billing descriptor is required to setup Ethoca and CDRN alerts.

A billing descriptor is the name that shows up on the charge within your customer's card statement. 

Here's how to find your billing descriptor:

Shopify Payments

Go to Settings > Payments > Manage

Scroll all the way down. Your billing descriptor will be visible at the bottom.

Stripe

Go to Settings > Public details

Your statement descriptor will be visible here.

If you're not using Stripe or Shopify Payments, you may need to ask your processor for your descriptor or make a test purchase from yourself to view your descriptor.
