Is there an API Call that allows me to send an SMS from Marketing Cloud without adding a new contact into All Contacts?
I tried to use this one, but a new contact has been created and subscripted to the keyword. { "mobileNumbers": [ "13175551212" ], "Subscribe": true, "Resubscribe": true, "keyword": "JOINSMS", "Override": true, "messageText": "Welcome to Code@", }
Do you have any suggestions?
