30109: Callback URL is invalid

This error occurs when the CallbackUrl in your Link Shortening domain configuration isn't a valid URL. Click event data is sent to this callback URL after a recipient clicks a shortened link.

• The CallbackUrl is missing a protocol such as http:// or https://.
• The hostname is invalid, incomplete, or malformed.
• The path or query string contains characters that aren't properly URL-encoded.
• You entered an invalid Click tracking callback URL in the Console, or sent an invalid CallbackUrl parameter in the request.

• Submit a fully qualified CallbackUrl that includes the protocol, hostname, and any required path.
• If you configure Link Shortening in the Console, update the Click tracking callback URL and save the domain configuration again.
• If you configure Link Shortening with the API, send a corrected CallbackUrl in a POST request to the Link Shortening domain's Config subresource.
• URL-encode special characters in the path and query string before you save or submit the callback URL.
