SoftEther VPN User Forum

I'm developing a VPNGate Client App. At the moment, I only want to retrive support for SSTP servers. I utilized the VPNGate Api https://www.vpngate.net/api/iphone/ and it's working great. But I want to only get servers that support SSTP Protocol. I request the VPNGate Team to add a new column protocols in the api which will has protocols that server supports separated by commas, so that I can get only the servers that I need.

Also do let me know if any donation or payment is required for that.
