Fetch sent/received SMS from Dialpad to be integrated with my custom application

Hi,

I am working on an application where I have to integrate sent/received messages from Dialpad via APIs. I checked the APIs but could not find any API, which I can use for this. I found one API https://dialpad.com/api/v2/sms_messages, but when accessing it, it says "Requested URL /api/v2/sms_messages not found".

Can you please help me to have a bit more information to achieve my task?

Any help would be greatly appreciated.

Many Thanks.
