Please help in the error. I am using constant contact php-api and I am facing the above problem, but it does not occur while creating a new contact while the same error occurs when I am updating a contact (when confirmed opt-in is turned on and the user has already confirmed the subscription). I dont get any error whether it is adding a new contact or updating an existing contact while the Confirmed opt-in is not used. I have already checked the email duplication its not the problem in my case so dont know what to do.
Please help me.
I would be happy to help you resolve this problem. In order to troubleshoot this further, it would be a great help to have some of the details on your API request that is returning a conflict error. If you can provide some of this information, that will help greatly:
I do also want to mention that if any of the above information is sensitive enough that you would prefer to not post it on a public forum, you can also provide this information by emailing us at email@example.com. If you do email us, please provide your Constant Contact username as well as information on which contact you are having issues with updating.
