30100: Domain SID is invalid

The Domain SID included in your request is not a valid Domain for your Twilio Organization.

The Domain SID you're using could belong to another Organization. It could also potentially be an issue of copy and pasting. You may be providing a Url instead of a Domain SID in the Domain SID field.

Double check the Domain SID's available for use within your account and ensure you're using one of those.
