We sent an SMS to a contact using the same API call
"POST /messageContact/{id}/send"
{ "Subscribers": [{ "MobileNumber": "39334320430",
"SubscriberKey": "11111" }],
"Subscribe": true,
"Resubscribe": false,
"keyword": "OK",
"Override": true,
"messageText": "Reply OK to +39333456576"
}
Then we changed the first mobile number with a second one related to this contact into a Data Extension.
We tried to send a second SMS with the same API parameters (obviously with a different MobileNumber). But we noticed that, despite the result of the call is accepted (code 202), in the Membership page inside Mobile connect, the system didn't add a new subscription and i didn't receive any SMS.
Is it a standard behavior in mobile connect feature? Do you have any advice?
