We use VBA code that loops through a recordset and sends SMS text messages to customers as appointment reminders. The SMS text messages sent are sent from the RC telephone number of the employee assigned to the customer receiving the SMS. Our existing code (using password auth) in our app has been working flawlessly for a long time.
In our existing app - using Password Auth - our request header is structured like this:
http.Send "grant_type=password" & "&username=" & strRCEmployeeTel & "&password=" & strRCEmployeePwd & "&extension=" & strRCEmployeeExtension
Later in the Password Auth code - we SEND the SMS from the RCEmployeeTel using this code:
http.Send "{" & """to"": [{""phoneNumber"": """ & strCustomerPhone & """}]," & """from"": {""phoneNumber"": """ & strRCEmployeeTel & """}," & """text"": """ & strMsg & """" & "}"
Moving to our JWT Auth app we are working on - our request header is structured like this:
http.Send "grant_type=urn%3Aietf%3Aparams%3Aoauth%3Agrant-type%3Ajwt-bearer&assertion=" & JWToken
Later in the JWT Auth code - when we attempt to SEND the SMS from the RCEmployeeTel using the same code as above:
http.send "{" & """to"": [{""phoneNumber"": """ & strCustomerPhone & """}]," & """from"": {""phoneNumber"": """ & strRCEmployeeTel & """}," & """text"": """ & strMsg & """" & "}"
We get this error:
{
"errorCode" : "FeatureNotAvailable",
"message" : "Phone number doesn't belong to extension",
"errors" : [ {
"errorCode" : "MSG-304",
"message" : "Phone number doesn't belong to extension"
} ]
}
We thought that the JWT would allow us to send SMS from any of our employee RC telephone numbers - but clearly that is not the case.
Can anyone suggest how we can address the above error?
