If adding of CNAME is not possible on the domain, then can TXT records created on DNS will also work for host mapping in zendesk? Kai April 09, 2023 20:46 Zendesk Customer Care Hi Amit,Creating TXT records instead of CNAME will not work for Hostmapping, since CNAME is one of the essential records that you need to set up for the host mapping to work as expected.
