In the Dashboard
The customer list, its export, and merging two customers into one.
Customers lists the records your payments and your integration create, with a timeline per customer, and their payments, refunds and disputes on their own tabs. Tags, groups and notes are editable there, and bulk actions apply a change across a selection.
Two tools have no API equivalent. Customers → Export produces a CSV or Excel of the list and is live only. Settings → Tools → Customer merges folds two customers into a single record, for duplicates the email and phone rules cannot see, such as one payer under two addresses.
