New Limits on Server side requests

Web3Forms API is expected to run on client side for spam prevention. If you call the API on the server side, you might get "this method is not allowed" or occasional "ratelimit" error because when you use it server side, each requests sent from one IP (your server IP address) which we use to prevent spam.

So, we will block such IPs and it will cause your forms will stop working permanently or temporarily. So we suggest you to use Web3Forms in client side code directly (HTML or Javascript) instead of proxying via backend API (eg: your own /contact API proxy) or in server side code directly.

If your use case requires you to use server side code, please contact support with your server IP address so that we can add them to safelist, so such error won't happen for your form. This custom request needs an active paid subscription (Pro or higher plans).
