You can use the following json code to construct a json object to be used for the `config` field or use the upstream doc for your specific domain provider [here](https://github.com/qdm12/ddns-updater#configuration):
My domain provider is `cloudflare`.
The `zone_identifier` or `Zone ID` is _per_ domain and can be found in the overview of the website/domain.
My host or the `A record` is set to `@`.
If the record is proxied through CLoudflare, set `proxied` to `true` or otherwise `false`.
The `token` is different from the API key. Please go to [api-tokens](https://dash.cloudflare.com/profile/api-tokens) in Cloudflare to create a `Edit zone DNS` token for your specific zone or domain.
:::caution
For security purposes create multiple different tokens for every domain you plan to add. **DO NOT** use a global token.
:::
The `ip_version` should always be `ipv4` unless your special :/.
