# 57009: 'EventType' is too long

Log Type: APPLICATION

Log Level: ERROR

## Description

Twilio returns this error when the `EventType` value in a Messaging webhook or status callback exceeds the accepted length. `EventType` is one of the fields Twilio includes in outbound message status callback requests for supported messaging channels.

### Possible causes

* The `EventType` value in the request is longer than Twilio accepts.
* Your webhook or callback payload includes extra text or formatting instead of the supported event identifier. This is an inference from the error and the documented callback shape.

### Possible solutions

* Send the documented `EventType` value exactly as required for the webhook or callback you are using.
* Remove any appended labels, whitespace, or other formatting before you send the request to Twilio. This is an inference based on the length error.
* If you are tracking outbound message delivery, use the Messaging webhook and status callback flow and make sure your endpoint handles the parameters Twilio sends.
