I created a trial Twilio account and configured WhatsApp with Twilio. I then configured the Twilio Account SID and Auth Token in Pega and configured the Pega webhook URL as the inbound message webhook in Twilio.
When I send a WhatsApp message, the message is successfully received by Twilio, but it is not reaching Pega.
Could someone please confirm whether a paid Twilio account is required for WhatsApp integration with Pega Digital Messaging, or if there is any additional configuration that I may have missed on the Pega or Twilio side?
