+## Add TXT record

+```
+https://<subdomain>:<subdomain_password>@www.dnshome.de/dyndns.php?acme=add&txt=<txtvalue>
+```
+
+- `<subdomain>`: the subdomain (ex: `lego.dnshome.de`).
+- `<subdomain_password>`: the subdomain password.
+- `<txtvalue>`: the value of the TXT record (12 characters minimum)
+
+Only one TXT record can be used for a subdomain.
+
+Always returns StatusOK (200)
+
+If the API call works the first word of the response body is `successfully`.
+
+Can be a POST or a GET, the HTTP method doesn't seem to have an impact.
