57007: 'EventType' is absent

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.

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

• 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.
