Similar to retrieving a DNS zone, you need to provide the UUID of the DNS zone that you want to export.
Prerequisite: You need an IONOS Cloud account with API credentials configured with the appropriate permissions.
To export an existing zone at IONOS Cloud DNS in a BIND format, follow this step:
Perform a GET request providing the zoneId of your zone.
Result: On a successful GET request, you receive the BIND file with the DNS zone having the UUID assigned.
Request
Copy curl --location --request GET 'https://dns.de-fra.ionos.com/zones/d6ba6fc1-fc82-4f0c-b030-2638778e0bef/zonefile' \
--header 'Authorization: Bearer eyJ0eXAiOiJKV1QiLCJraWQiO' \

Zone file
The exported zone file is in BIND format, a widely used format supported by most DNS software, including the BIND DNS server.
The file includes all record types associated with the selected zone, including SOA record, NS record, Service (SRV) record, and configuration information such as TTL values.
An example of a file in BIND format with an updated SRV record is as follows:
