How to update the distribution stat via API?

Hello,
I am sending Survey URL by SMS and Email using a custom application out of Qualtrics. This URL is individual for each contact. I am exporting URL and contact list from Qualtrics and sending from custom NodeJS application
After sending URL to the contacts, I need to update to Qualtrics about these contacts survey URL delivered. Just update Qualtrics who are all successfully received the survey. Could you please some one tell me which API ,I have to use and what are the parameters to be updated while sending from outside Qualtrics.
basically something similar like below, I need to update : "sent" :1
"stats": {
"sent": 0,
"failed": 0,
"started": 5,
"bounced": 0,
"opened": 5,
"skipped": 0,
"finished": 4,
"complaints": 0,
"blocked": 0
}
},
