409 Conflict

409 Conflict

I am trying to add several contact lists with random names from a .NET app using your C# sdk.

 

However, I can't seem to get any other response than 409 Conflict.

I get the same response when using your v2 API tester/debugger using both your example payload and random names. I have read that this error message indicates that a list with that name already exists, but I am positive a list with these names does not exist.

 

Example JSON payload:

 

    {
       "name": "Hot Opportunities",
        "status": "ACTIVE"
    }

 

The response I get:

    

    "error_key": "http.status.conflict"

    "error_message": "There was a conflict between the supplied data and the existing resource."

Re: 409 Conflict

There is a 1000 list limit in our new Contact Management platform.  It definitely could be that limit you're running into, which was added roughly a month ago.  It looks like our error message for that limit is not very good.  Will open a defect on our side to investigate and update the error message.

Re: 409 Conflict

I tested your JSON Payload against my account and was able to create a list no problem with the content you're sending over.  I assume you're using the POST request to create a contact list?  Here is what I received:

Here is what I see:

However, this morning when I look at our lists I see a message warning me that we are at our limit of 1,000 lists. Could this response be caused by trying to add a list that would put you over the maximum list limit?

Re: 409 Conflict

Ok, looks like we will have to find a way to limit our list creation.

Thanks for the info and quick responses.

Re: 409 Conflict

Hi,

Please help in "There was a conflict between the supplied data and the existing resource" error.

I am using constant contact php-api and I am getting the above mentioned error, 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 on he has confirmed the subscription). Also 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 problem its related to email duplication.Dont know what to do, Please help me.

 

Thanks,

MAK

Re: 409 Conflict

Posted a response on some of your other posts.  This is not related to the original topic but we did mention this defect in our May release notes: http://developer.constantcontact.com/docs/release-notes/may-2014-rel-notes.html.  We are working on fixing this defect now and hope to have it in a future release.
