+### TransIP
+
+You will need to generate an API key from the TransIP Control Panel at https://www.transip.nl/cp/account/api/.
+
+The propagation limit will be automatically raised to 240 seconds.
+
+Example configuration:
+```yaml
+email: hello@home-assistant.io
+domains:
+  - your.domain.tld
+certfile: fullchain.pem
+keyfile: privkey.pem
+challenge: dns
+dns:
+  provider: dns-transip
