# 13621: Invalid 'recordingStatusCallbackEvent'

Log Level: ERROR

## Description

Twilio returns this error when one or more values in `recordingStatusCallbackEvent` are invalid. Valid values are `in-progress`, `completed`, and `absent`. If you set `recordingStatusCallback` without `recordingStatusCallbackEvent`, Twilio sends `completed` by default.

### Possible causes

* `recordingStatusCallbackEvent` includes a value other than `in-progress`, `completed`, or `absent`.
* Multiple callback events are separated with commas or another delimiter instead of spaces.

### Possible solutions

* Update `recordingStatusCallbackEvent` to use only supported values, separated by spaces, such as `in-progress completed`.
* Remove `recordingStatusCallbackEvent` if you only need the default `completed` callback.
