Hello, first at all, sorry about my English. My name is Ezequiel and I'm from Argentina and I'm trying to send messages to contacts that I have scheduled in an Access database.
There is a way to do it directly from Access or it would also be useful to do it from Visual Basic. Thank you.
If I understand your requirement correctly, you want to use Messenger Bot API to send a chat message to specific user on the Messenger. Is this correct?
Basically, the API just provides a set of HTTP requests to send and receive a message from the system. I believe that you should be able to use VB.NET /C# HTTP Client class to send the HTTP requests.
Please refer to a set of HTTP request messages you need to send/receive and its limitation from the following Messenger Bot document.
