Wanted to make sure we gave an update on this.  Our Contacts Management team has gone through all of our accounts in production and merged duplicate Contacts into single records.  This was only Contacts with identical information, I.E. accidental duplications from multiple imports.   We do support having the same email address on multiple Contacts, so having multiple Contacts with the same email address is considered a valid use case.  We believe we accounted for the vast majority of the duplication reported by developers in this thread in our cleanup efforts.  If anyone sees something which should have been accounted for but was not, please provide information such as the account name (or email use the account information via webservices@constantcontact.com) so we can check out the specifics of those accounts.   We do have an open issue where duplicate Contacts can be created through parallel requests in the API (two POST requests with the same information occuring virtually at the same time).  Long term, we want to put some defensive meassures in place to prevent this.  However, this is not a simple problem for us to solve and it is not a short term fix for us.  In the short term, we recommend to developers to not attempt to POST the exact same Contact information at the same time.  ...

We have not found any specific issues.  I do want to reiterate my earlier post, we neither recommend nor support using an iFrame for security purposes and highly recommend using a popup window.  We will keep this on our list to investigate and see if there are issues but since we do not support iFrame flows for our OAuth process, this would be low priority for us if fixed at all. ...

It does sound like you are doing a single contact add as the error you receive is only through the single contact add.  Basically, that error means that a contact is trying to be modified or created in a state that requires ACTION_BY_VISITOR (indicating the Contact asked to be subscribed).  There are a few reasons that could occur, most commonly that the contact already exists, is opted out and you are attempting to opt them back in.   We would need to see the raw information about the Contact you're trying to create/update, the payloads and do some investigation to get you a more detailed answer than this.  If you could email our API support team (webservices@constantcontact.com) with the details that would help.    Also wanted to point out, we do not permanently delete Contacts.  If you use the "Delete" option in our web UI, the Contacts are marked as "deleted" but stay in the database forever.  Thus, the API integration is likely trying to update one of those deleted Contacts and there is a disconnect in the states. ...

Hi Caroline,   I'm referring you to our comprehensive API documentation resources on our developer portal.    When you retrieve the details for a contact, it includes the lists that they are a member of. So, if you know the contact's email address that you added to the list, you can search on that as described here in the documentation. You will know which list that the contact is a member of. Then you can GET the Contactlist membership as described here.   Let me know if this helps you with the issue you are experiencing. ... View more

Hello,   Thanks for posting in the forums.  We're going to be adding this to the documentation in the near future, but here's an example cURL request that will perform a contact upload:   curl -i -H "Authorization: Bearer <TOKEN>" -H "Content-Type: multipart/form-data" -H "Accept: application/json" -X POST -F 'lists=<LIST_ID(S)>' -F 'file_name=contacts.txt' -F 'column_names=EMAIL' -F 'data=@contacts.txt' "https://api.constantcontact.com/v2/activities/addcontacts?api_key=<API_KEY>";   This request implies that the file is in the same directory that the cURL request is run in, and that there is only one column of information.  The file_name parameter should match the file pointed to in the data parameter.  You can add column_names based on the listed parameters here:   https://developer.constantcontact.com/docs/bulk_activities_api/bulk-activities-addcontact-multipart.html   Be sure to follow the other constraints specified by the documentation.  I hope the information helps.   Regards,   Andrew B.

I did a global search in the sdk for private set and patched to remove the word "private". Rebuilt the sdk and I'm still having problems. Here is a somewhat more detailed description of what's happening to me.   Use the following method to retrieve a list of contacts         public static ResultSet<Contact> GetContactFromList(string listId)         {             ContactList cl = api.GetList(listId);             Pagination pag;             //Get first (up to) 50 individuals             ResultSet<Contact> retVal = api.GetContactsFromList(cl);             pag = retVal.Meta.Pagination;             //Retrieve the rest (if any)             while (pag.Next != null)             {                 ResultSet<Contact> moreFolks = api.GetContactsFromList(pag);                 foreach (Contact c in moreFolks.Results)                     retVal.Results.Add(c);                 pag = moreFolks.Meta.Pagination;             }                         return retVal;         } Caller invokes this method like this...             ContactList previouslyRemovedList = CCAPIAAccess.GetList(ConfigurationManager.AppSettings["RemovedSaveList"]); Then...             try             {              foreach (Contact c in contactsToBeRemoved.Results)              {    ...                  //Retrieving contact because I notice that the GetContactsFromList only retrieves skeleton Contact objects                  Contact c1 = CCAPIAAccess.api.GetContact(c.Id);    //Not shown here is code where I used GetList to retrieve previouslyRemovedList                  c1.Lists.Add(previouslyRemovedList);           ...              }             }      catch (Exception e)      {   //e.Message states that "Collection was of a fixed size."             } ...

Hello,   Thanks for posting on the forums.  We have a group of ContactList endpoints, one of which will allow you to retrieve the membership of a particular list.  Details on the endpoint are here:   http://developer.constantcontact.com/docs/contact-list-api/contactlist-membership-collection.html   The short of it is, make a GET call to the following URL:   https://api.constantcontact.com/v2/lists/{listId}/contacts   You will get a paginated response back that contains an array of contacts in the particular list.  This will allow you to retrieve contacts from a list.  I hope the information helps.   Andrew B.

Hello,   Thanks for posting on the forums.  I'm not quite sure why you are getting the error.  Can you provide a more complete code snippet or the body of the request that is returning the error?  Feel free to PM me.   Regards,   Andrew B. Constant Contact, API Support ... View more

Here's an update.  We have been able to reproduce the problem and it is logged as a defect to be fixed.  We were also able to determine a workaround until the fix is live.  If there is a custom field with a comma in the value, you can wrap the field in escaped double quotes to ensure correct processing.    So this:   {      "name":"Custom Field 1",      "value":"test, test" }   Becomes this:   {      "name":"Custom Field 1",      "value":"\"test, test\"" }   I'll provide another update once I know when the fix should be released. ...

Your idea is great in theory, but Constant Contact does not allow it.  I've tried every which way from Sunday to use a custom field inside of a link and it seems to be impossible. PLEASE PROVE ME WRONG. At first I thought the issue was related to using single and double quotes, but that appears to irrelevant. In order to create a hyperlynk you have to start with <a href="Then your link goes here">link text</a>  But in order to use a custom field you have to use something like:  <Property name="SUBSCRIBER.ADDRESSLINE3"/> Which gives you the following code:   <a href=' <Property name="SUBSCRIBER.ADDRESSLINE3"/>' >link text</a> (I switched the double quotes in the href out for single quotes so that the double quotes around the name would not cancel out the href and it still doesn't work.   It appears that Constant Contact cannot think of a scenario where you would ever want to link to a custom field, much less link an image to a custom field. ...

Wanted to give a quick update here.  Looks like this is an issue with using bulk imports only with our new Contact Management System that we're moving our customers over and is really a false alarm (the imports actually succeed).  We're working on fixing this up and hope to have this cleared up soon so that we can get back to giving you accurate errors in the bulk imports.  Don't have an expected date yet for this fix but will update once we get one. ...

The content should be escaped automatically when the object is converted to JSON, so in the case of your production server it will be double escaped causing us to fail parsing on our side when we decode the JSON.  Very strange that it's getting escaped twice, is it the exact same code on both environments?  Are you storing the HTML somewhere and retrieving it and potentially encoding it along the way? ...
