# 14105: Invalid statusCallback attribute

Log Level: WARNING

## Description

Twilio returns this warning when the `<Message>` verb includes a `statusCallback` attribute that is not a valid URL. The `statusCallback` attribute accepts a relative or absolute URL. If you use an absolute URL, it must contain a valid hostname and the hostname cannot include underscores.

### Possible causes

* The `<Message>` verb includes a `statusCallback` value that is empty, malformed, or not formatted as a relative or absolute URL.
* The `statusCallback` value uses an absolute URL with an invalid hostname. This includes hostnames that contain underscores.
* The callback URL contains a typo, incorrect domain, or invalid path. ([help.twilio.com](https://help.twilio.com/articles/43659166532123))

### Possible solutions

* Update the `statusCallback` attribute so it contains a valid relative URL or a fully qualified absolute URL.
* If you use an absolute URL, make sure the hostname is valid and remove any underscores from the domain name.
* If you need a custom status webhook for `<Message>`, set both `statusCallback` and `action` to the same URL. This helps you avoid undefined behavior across message types while Twilio normalizes attribute handling.
* Test the callback URL with a temporary public webhook endpoint to confirm Twilio can send requests successfully, then switch back to your production endpoint after the test passes. ([help.twilio.com](https://help.twilio.com/articles/43659166532123))
