# 11001: Website URL doesn’t match the required format

Log Type: TWILIO

Log Level: ERROR

## Description

The website URL must be in a valid format, starting with https:// and followed by a valid domain name (e.g., https://example.com).

### Possible causes

The URL doesn't start with https://.

The URL contains typos, spaces, or unsupported characters.

The domain name is incomplete or missing (e.g., "https://example" instead of "https://example.com" ).

The URL includes extra paths or parameters that make it invalid.

The URL uses an unsupported protocol (e.g., http:// or ftp://).

### Possible solutions

Please review the possible causes and update the linked profile with the correct information:

* Enter the full website URL in the Profile Website field, starting with https://.
* Verify the domain name is complete and valid (e.g., https://example.com ) before saving the profile.
* Remove any spaces, typos, or special characters from the website URL in the profile.
* Ensure the website uses the https:// protocol - other protocols (e.g., http://, ftp://) are not supported.
