`GET https://api.vigilbase.com/one/v1/support-tickets/{ticketId}/messages`

The conversation on one support request, oldest first (the newest 200 messages). Staff must name the customer with customerId; everyone else gets their own organisation’s customer.

> Deprecated aliases: `GET https://one.vigilbase.com/api/support/tickets/{issueId}/messages`. They answer with the same bodies, with a `Deprecation` header and a `successor-version` link to this URL.
