We recently released a new Velo Package - static-ip-request
Wix is a cloud-based platform with a dynamic IP address. With the Static IP Request package, you can easily get a static IP address for your Wix site, enabling you to perform HTTP requests from your Wix site to 3rd-party services that require a static IP address for authentication.
Check out the Velo Packages article to learn more, or make a request for a new package.
Thanks for this. I have followed the article. But is there any tutorial where i can find how to use it.
