hi I want to qualify leads from FB ads using a call from vapi but I get error 400-bad request. But I get the same error when I put the data directly. i tried USA number but I am primarily working with Czech. Can anyone help me? https://cdn.discordapp.com/attachments/1294321839488761933/1294321840000598097/Snimek_obrazovky_2024-10-11_v_17.31.15.png?ex=670a96a5&is=67094525&hm=e3178433b2a27fbc554a70a8bcdc64ef669aed55e900d17df962bb9df2f831de&

@Martin-AI Hello! I'd be happy to assist you with your issue. To help you effectively, I need a bit more information about the call you're trying to make. Could you please provide me with the exact request you're sending to the VAPI, including the body and headers (excluding your Authorization token for security reasons)? This will help me understand where the issue might be occurring. If you're working with phone numbers from different countries, make sure you're using the correct international dialing format.

hey either use customer phonenumber or customer id because customer id means actual record in vapi db. so better use customer phone number only.
