Using V1 API we get 400 Bad Request returned from server when attempting to upload a new contact individual using CreateNewContact API. I have a suspicion this relates to the problem I reported recently in item titled..."using version 1 api Not able to retrive more than 50 contacts from Do Not Mail list.".
Thanks in advance...Mike Cravitz
Hi Mike,
400 error when creating a Contact is usually related to a data issue. Have you looked at the returned error message to see what we are saying is wrong? 400 Bad Request is a data validation failure and we usually return a detailed error of what the problem was, or at least which node had the bad data. If you could share your code, that would help as well.
