Hi there,
I have noticed that my Invoke Web Service request are being blocked until I use User Agent Mozilla 5.0. Although this time I was sending a request to WhatsApp Cloud API and I got the error below.
{"error":{"message":"(#100) The parameter file is required.","code":100,"type":"OAuthException","fbtrace_id":"A-MpfHoy11gyLCCWreKv8hX"}}
