# Set payment QR

Changes the payment link a charger shows as a QR on its display. Plugchoice writes it with `ChangeConfiguration`. Returns `204 No Content` when the charger accepts it.

**charger** `string` *required*

The UUID of the charger.

**template** `string` *required*

A link that starts with `https://`, at most 100 characters. Use `{chargingstationid}` and `{evse}` where the charger should put its Chargepoint ID and the connector number. An empty string removes the QR from the display.

## Errors

| Status | When |
| - | - |
| `400` | The charger is offline. |
| `422` | The link does not start with `https://` or is too long, or the charger did not accept it. In that last case the body has `reason` set to `value_rejected`. |
