I've been trying to use Zoopla's property search API a few days now. First day I used the API, it was straight forward. I registered for a new key, and could do requests via the documentation. Starting yesterday, all the requests I would do would always return a 403 response with the body <h1>Developer Inactive</h1>.
I tried creating a new API key but the problem is still the same. Is anyone using the API that can share some knowledge about it? Seems to be deprecated, but I cannot understand how I was getting results from it without issues for a single day.
