# Customer Email Check

This enhancement addresses a recurring issue that has been consistently reported – various issues arising from merchants inadvertently mixing reusable links with individual authorisation links, leading to customer confusion and a range of problems.

#### **How it Works**

If the Billing Request has customer details captured (via linked customer, prefilled data, or if a customer has already initiated the flow and provided their email), when the authorisation link is opened, a payer will encounter a prompt to enter their email.

- If the entered email matches the captured one, the payer will be able to proceed with the current Billing Request Flow.
- If the emails don't match, a new authorisation link will be generated (if possible, i.e., Billing Request is created from a paylink or a plan link) and the user will be redirected to a new, empty flow. If creating a new link is not possible, an error page is displayed.

If customer details aren't captured, the flow proceeds without changes.

###### Happy path: Resume the flow

1. Submitting the email which matches the captured one:

2. Proceeding with the current flow:

###### Happy path: Generate a new flow

1. Submitting the email which does NOT match the captured one:

2. Being redirected with a new authorisation link to the new flow:

###### Unhappy path: Auto-generating a new flow is not possible

1. Submitting the email which does NOT match the captured one:

2. Seeing an error:
