# List customers

List the people who have paid you or started to, with totals for each.

`GET https://dash.402pay.co/api/v1/customers`

A customer is added when checkout collects an email, when a payment names one in `customer_email`, or when you [create one](https://developer.402pay.co/api/customers/create.md), so a customer can have no payments yet. In `stats`, `payments_count` and `volume` count succeeded payments, and `incomplete_count` counts the rest.

### Query

- `q` (string): Matches the name, email or ID.
- `blocked` (boolean): `true` or `false`.
- `sort` (string): `created_at`, `last_payment_at`, `payments_count`, `volume` or `name`, with `-` for descending. Defaults to `-last_payment_at`.
- `limit` (integer): Page size, from 1 to 100. Defaults to 25.
- `cursor` (string): The `next_cursor` from the previous page. See [pagination](https://developer.402pay.co/api/pagination.md).

### Errors

- 400 `invalid_request` A filter has a value it can't take, or the `cursor` belongs to another list.

Any request can also fail on its key or its body. See [errors](https://developer.402pay.co/api/errors.md).
