Cloudflare wrote to me today to say that I’m using v1 of their API not v4 and that I have two weeks to migrate to v4. In a panic I checked how we are updating our DDNS records in cloudflare and realised that we are using ddclient and following the instructions at https://www.cloudflare.com/technical-resources/#ddclient.
How then is it possible that we are using v1 of the API? Surely the instructions on cloudflares’ own website are using v4 of the API??? How can I work out what is really going on here? Did cloudflare send me this email in error?
