Available since `1.26.0`

Messengers are used to send messages from within FusionAuth to other systems.

## Message Types

Beginning in version `1.65.0`, each messenger can be configured with one or more message types in **messageTypes**. This tells FusionAuth which workflows the messenger may be assigned to.

For example, when configuring SMS or Voice settings in [multi-factor configuration](https://fusionauth.io/docs/lifecycle/authenticate-users/multi-factor-authentication.md#tenant-mfa-settings-enable-methods-policies-templates) on a tenant, you can assign a messenger that supports the corresponding message type.

The legacy **transport** field remains for backward compatibility, but it is deprecated.

## Set Up a Messenger

In FusionAuth, you can use the following types of messengers:

*   [Generic Messenger](https://fusionauth.io/docs/messengers/generic-messenger.md)
*   [Twilio Messenger](https://fusionauth.io/docs/messengers/twilio-messenger.md)

To configure a Messenger, navigate to Settings -> Messengers and select the appropriate Messenger type from the dropdown in the top right.

## Message Templates

Message Templates support the following message types:

*   Text
*   Voice

Each template can be customized and localized. FusionAuth uses FreeMarker for all templates.

*   [Manage Message Templates](https://fusionauth.io/docs/messengers/message-templates.md)

To configure a message template, navigate to Customizations -> Message Templates .

To modify Messenger templates using the API, see [Messenger Template APIs](https://fusionauth.io/docs/apis/messengers.md).
