How to use VBA to send and receive SMS messages
Has anyone been able to use VBA (Visual Basic for Applications) to send and receive SMS? I've tried the code posted in a response in this forum, but can't get past getting an access token. No matter what I try, I get the error "Client authentication is required", error code OAU-123. I would be glad to pay for some consulting time with anyone who can help me.
