+## 196. Use CZECHIA.COM DNS API
+Get your API Authorization Token from the CZECHIA/RegZone, see [here](https://www.regzone.info/rest-api-terms)
+
+Export the required credentials:
+
+``` sh
+export CZ_AuthorizationToken="your_api_token"
+export CZ_Zone="example.com"
+```
+
+If you manage multiple zones, you can specify them as a comma-separated
+list:
+
+``` sh
+export CZ_Zones="example.com,example.net"
+```
+
+Then issue a certificate using the dns_czechia provider:
+
+``` sh
+acme.sh --issue --dns dns_czechia -d example.com -d '*.example.com'
+```
+
+Notes:
+
+-   `CZ_Zone` (or `CZ_Zones`) must contain the apex domain name(s), not
+    the `_acme-challenge` subdomain.
+-   TXT record changes for ACME DNS-01 validation do not require IP
+    whitelisting.
+-   Credentials are automatically saved to `account.conf` for future
+    renewals.
