# 57007: 'EventType' is absent

Log Type: APPLICATION

Log Level: ERROR

## Description

Twilio returns 57007 when a request reaches Twilio without the `EventType` parameter. Use Programmable Messaging Logs and Debugging Tools to inspect the failing request and confirm what your application sent.

### Possible causes

* Your application did not include `EventType` in the request.
* The request was built incorrectly, so `EventType` never reached Twilio.

### Possible solutions

* Add the `EventType` parameter to the request and send it again.
* Check Programmable Messaging Logs, then use Debugging Tools to inspect the request details and confirm the parameter is present.
