Use this endpoint to decide which channels to offer to a user before you create a verification. For example, show a WhatsApp option only in countries where `whatsapp` is listed. The list does not say whether a specific phone number can receive a channel. For example, it does not say whether the user has WhatsApp. If a channel cannot reach the phone number, Prelude falls back to the next channel. `voice` and `silent` can appear in the list, but they are not values of the `channels` option of the create verification endpoint. Request voice with the `method` option set to `voice`. Silent verification needs the Prelude SDK on the user's device. The list is per country. It does not show channels that are closed for one platform only (for example web only) in the dashboard. The result changes rarely. Refresh it periodically (for example once a day) instead of calling it before every verification. In order to get access to this endpoint, contact our support team.
