My server's API requests to ClickFunnels are being blocked

Hi,

I'm trying to make API requests from my server to a ClickFunnels workspace, but I'm getting blocked.
I'm not sure if ClickFunnels uses Cloudflare or another security system, but every request returns a 403 Forbidden error.

I've tried allowing my server's IP and making the request with standard headers, but nothing works.
Is there any way to fix this or someone I should contact to get my server unblocked?

Thanks in advance for any help.
