[jackb101]

We are having an issue where the FirstName and LastName of are contact are not updated in constantcontacs by the json api call when I am trying to set the to no value. In cinstantcontacts, the previous value is kept. There is no error message. What am I doing wrong

Hello,

Thank you for reaching out to the API Support team here at Constant Contact. I'd be happy to help in any way I can.

Can you provide us with an example of what call you are making? Specifically, the endpoint you are using and the full body of your request.

Once we have this information we can begin looking for potential problems that could cause an issue.

Sincerely,
David B.
