I'm looking at this code: https://github.com/venomous0x/WhatsAPI On the page: /src/php/EXAMPLES.php I've made the following changes (which I think is all I need to amend. I have obviously used different IMEI number and Mobile numbers for this example): $userPhone ='447799999999';# Telephone number including the country code without '+' or '00'. $userIdentity ='98B898B898B8';# This is tipically the IMEI number.# If you are using an iOS device you should input your WLAN MAC address. $userName ='John Doe';# This is the username displayed by WhatsApp clients. $destinationPhone ='447788888888';# Destination telephone number including the country code without '+' or '00'.# For groups: [phone number]-[group id]. $debug = TRUE; $w->requestCode('sms','GB','en'); $w->registerCode('123456'); but when navigating to this example.php page on my server I receive the following error: Fatal error: Uncaught exception 'Exception' with message 'There was a problem trying to request the code.' in /whatsapp/src/php/whatsprot.class.php:1174 Stack trace: #0 /whatsapp/src/php/EXAMPLES.php(49): WhatsProt->requestCode('sms', 'GB', 'en') #1 {main} thrown in /whatsapp/src/php/whatsprot.class.php on line 1174I just want to know where I'm going wrong, can anyone shed some light? Thanks
