Documentation Reference for Custom Dynamic DNS Setup like Custom HTTP Requests?

[lbwarped]

Hello! The Dynamic DNS documentation page mentions custom HTTP requests being possible with the Native Dynamic DNS backend, but does not offer any specifics about how it can be configured.

I am using NameSilo as my domain provider, and would like to use their API to update a subdomain for Dynamic DNS purposes. Their API page linked above provides a sample request along with all the possible available parameters to use.

Can someone please help me understand if it is possible to construct a URL that this API requires with the various parameters, and how I would do so using the OPNsense Dynamic DNS Native backend? In particular, it would be helpful to understand the differences between "Custom GET", "Custom POST", and "Custom PUT".

Thank you!
