hello @seejacksonhole. we don't ever change ID of the webcam, that has to be some confusion on your side. the webcam can however be disabled (happens from time to time), or be merged with some other webcam (in such case, old merged webcam is redirected to the new one). In any case, unless the webcam is disabled, original link will always work (unless you are doing some undocumented/unsupported hacking...)
I found the culprit for this: it ends up that I have used old key and base URL (before integration with windy.com). It worked fine few months but not any more. With new key and new base URL: https://api.windy.com/api/webcams/v2/, everything works fine.
Okay, I think I misunderstood the the response data. I'm guessing total refers to the total number of webcams, and the regions field lists all of the available regions. In which case, this is definitely enough.
