@fabi Hello! I'm sorry to hear that you're having trouble accessing the API reference page. It's possible that there might be a temporary issue with the website or it could be an issue with your internet connection. Here are a few steps you can try to resolve the problem: 1. Check your internet connection to ensure it's stable and active. 2. Try refreshing the page or clearing your browser cache and cookies. 3. Attempt to access the page using a different browser or device to see if the issue persists. 4. If you're behind a firewall or using a VPN, try disabling these to see if they might be blocking access to the page. If none of these steps work, the issue might be on the server side, and it would be best to wait for a while and try again later. If you need immediate assistance with the Create Phone Call API, I can help answer any questions you might have. Just let me know what you need!
