## Error - 52203

### Missing body for Facebook Messenger delivery attempt

Messenger messages need to have some content. You can specify this either via the [generic Body parameter](/docs/api/notify/rest/notifications#generic-payload-parameters) of the Notification request or the [FacebookMessenger channel specific parameter](/docs/api/notify/rest/notifications#channel-specific-parameters).

#### Possible causes

- Notification has neither Body not FacebookMessenger parameter set

#### Possible solutions

- Specify either Body or FacebookMessenger parameter when sending a Notification
