Hello,   Thanks for posting in the forums.  How are you adding the contacts?  Are you adding them one at a time, or all at once as an activity?  Depending on how the contacts were removed (whether there status is REMOVED or OPTOUT), the preexisting contacts have to be added back in individually.  Some more information on that is here: http://developer.constantcontact.com/docs/contacts-api/contacts-index.html#contact_status   Regards,   Andrew B. API Support ... View more

Hello,   Thanks for posting in the forums.  I was able to perform both a POST (add) and PUT (update) request using the template you provided.  Can you provide some more information detailing the requests you are trying to do?  Can you PM me the account username and the URL you are calling?    Thanks,   Andrew B.

Thanks for the information.  I passed it along to a developer who will be performing an investigation, to try to figure out what happened.  I'll be in touch at intervals with a status or when I have an answer.   -Andrew ... View more

Hello,   Thanks for posting in the forums.  Would you mind sending me a PM with the account details, or emailing webservices@constantcontact.com.  It looks like something unexpected may have happened when the accounts was migrated to the new CMS.  We'll need to perform an investigation.   Regards,   Andrew B.

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. API Support, Constant Contact ... View more

Hello,   Thanks for posting!  It looks like the set methods for some attributes have been set to private in the SDK.  Removing the private modifier in the set method of the Contacts object will remove the read-only effect of the attribute.  Its strange to see a private set method with no way in the class to pass a message.  I'm updating the SDK in our repo now to make the set methods public.   Regards,   Andrew B. API Support, Constant Contact ... View more

Took a look at the SDK (based on the code, the php sdk).  The deleteContactFromList method needs the contact's id as a parameter as a string.  Can you try passing just the contact id string, instead of the entire $ctct, which looks like a Contact object?   Edit:  The contact id is an int, sorry. ...

Right now there is a delay in the UI reflecting changes made to an account using the API.  So even though you are correctly removing a contact, it will not change in the UI right away.  There is a defect logged to resolve the issue, but I don't have a time frame for its resolution right now.  The best way to check if a contact has been removed at the moment is to verify it through the API. ...

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 in the forums.  What you are experiencing definitely looks like it could be some issue on our end.  Would you PM me some more details of what is going on.  Contents of the response body that omitted the two events or the account/ token the endpoint was called on would be helpful.  Thanks.   Regards,   Andrew B.

Hello,   Thanks for posting in the forums.  We are currently experiencing an issue with causes valid bulk remove contacts to fail on both the v1 and v2 APIs.  Unfortunately, I don't have a timeline for when the bug will be fixed.  I'll provide updates here when I get some more information.  Sorry for the inconvenience.   Regards,   Andrew B.

Hello,   Thanks for posting on the forums.  The GetCampaigns method currently returns the campaigns in reverse chronological order, so you would get the "newest" campaigns first.  Your code looks fine.  Have you been able to been able to sort out what happened with your results?   Regards,   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. ...

Hello,   The errors you got back are because of the duplicate contacts.  We don't have a method for developers to clear out duplicate contacts right now.  We will most likely be removing the duplicates ourselves once the bug has been fixed.   You should still be able to view the bulk activities performed by the API through the UI.  The URL may have changed.  When you look at your contacts in the UI, there is a tab labeled "Activity" that should provide that information.   Regards,   Andrew B. Constant Contact, API Support   EDIT:   Sorry, you are correct.  The new UI does not currently show API activities.  I have been told that this is supposed to be fixed in the near future, but I don't have a time for this. ...

Hello,   Thanks for posting.  Our API allows XHTML emails, in addition to normal HTML emails.  XHTML emails allow you to include dynamic content, based on the individual it goes to.  A full how to use XHTML is in our advanced editor guide, located here:   http://img.constantcontact.com/docs/pdf/building-your-emails-with-the-advanced-editor-tool-constant-contact.pdf   So you could instert <Property name="Subscriber.CustomField1"/> into a url to embed the custom field you wanted.  There is tighter validation with XHTML (specified in the guide), so you may need to make some additional changes as well.  I hope the information helps.   Andrew B.
