# 17585: Invalid status callback URL

Log Type: APPLICATION

Log Level: WARNING

## Description

The configured status callback URL isn't a valid, well-formed HTTP or HTTPS URL, so Twilio did not attempt to deliver the transcription status event. The transcription itself is unaffected.

### Possible causes

* The URL has a malformed scheme.
* The URL is missing a host.
* The URL uses a protocol other than HTTP or HTTPS.

### Possible solutions

* Correct the callback URL in the transcription configuration so that it is a fully-qualified HTTP or HTTPS URL.
