I do wish you expressed your concerns in an email before jumping to conclusions and giving the plugin a one-star. There’s nothing to be suspicious about, as your credit card isn’t stored on the website and goes through Stripe. As for the API, you are only charged for what you use. The plugin may work but due to some limitations with Bunny.net, you have to change your Storage Region zone if you aren’t on the default.
It looks something like this:
https://bunnyapi.com/?key=%5BAPIKEY%5D&action=setstorageregion&zone=zone&host=main|ny|la|sg|syd
Although the plugin is slightly out of date currently and we are working to update so it would work no matter what storage region was chosen. It still works if you are in the correct storage region. But you are correct that we are a third-party and not associated with Bunny.net, though we do provide the link in between.
If you need any assistance, we can provide the support. Apologies for the plugin not working for you, but clarifying that we are legit business and do not steal your information.
