# Set encoded OCPP Password (AuthorizationKey) for a charger

`POST /chargers/{chargerId}/ocpp/settings/encodedauthorizationkey`

## Request

- Base URL: `http://integrations.api.prod.zaptec.com`
- URL: `http://integrations.api.prod.zaptec.com/chargers/{chargerId}/ocpp/settings/encodedauthorizationkey`
- Auth: HTTP bearer

Sets the charger's OCPP AuthorizationKey from `encodedPassword` and configures the charger to use that encoded key as-is (without decoding).

Expected `encodedPassword` format is an OCPP AuthorizationKey encoded as hexadecimal text (typically 32-40 hex characters).

If you want default password handling, use `/chargers/{chargerId}/ocpp/settings/password` instead.
