You can disable the Change of Interest email by using ACTION_BY_CUSTOMER for all actions except for opting back in.  You can do this by first checking to see if the contact has a Do Not Mail status.  If it does, you would need to do an ACTION_BY_CONTACT which would be the only situation where the Change of Interest email would be sent.   Thanks, ...

Hi Jason,   Any time you are managing your list on your own, you should be using   "ACTION_BY_CUSTOMER".  This will prevent the Change of Interest email from going out.  You could set it up so that "ACTION_BY_CONTACT" is only used when a customer is opting back into your list.  They will receive the Change of Interest email, but at least they will be expecting it.   Thanks, ...

Hi, It looks like the problem is with how your XML is formatted.  When I changed the spacing so that each node is on a separate line, it worked for me.  I have included an example below: <entry xmlns="http://www.w3.org/2005/Atom"> <title type="text"></title> <updated>2011-08-25T01:21:06.407Z</updated> <author></author> <id>data:,none</id> <summary type="text">Contact</summary> <content type="application/vnd.ctct+xml"> <Contact xmlns="http://ws.constantcontact.com/ns/1.0/"> <EmailAddress>bobp@vinomis.com</EmailAddress> <OptInSource>ACTION_BY_CUSTOMER</OptInSource> <ContactLists> <ContactList id="http://api.constantcontact.com/ws/customers/***/lists/1"/> </ContactLists> </Contact> </content> </entry>   I hope this helps.  Please let me know if I can be of further assistance. ...

Hi Shameer, Yes, you can add an email address into multiple lists using the API. I suspect the issue is that you are trying to do a POST for a contact that already exists. When you are adding a contact for the first time, you should perform a POST.  However, when you are updating a contact (when the contact already exists in your account), you need to perform a PUT. So, I recommend first checking if the contact already exists.  If it does, update it via a PUT.  If it doesn't, add it via a POST.  Keep in mind that when updating and doing a PUT, it will remove the contact from whatever list(s) they are on and only add them to the list(s) that are specified in the PUT statement. I hope this helps! ... View more

Hi, I believe that the problem lies in the following isset statement: else { $search = $ConstantContact->searchContactsByEmail($email); if(isset($search)) Currently, this is just checking to see if the $search variable has been declared.  Since it was declared, this will always be true.  So, you should remove isset so that the statement appears as follows: else { $search = $ConstantContact->searchContactsByEmail($email); if($search) I hope this helps!

Thanks for providing your code.  We are going to look into this and I will get back to you as soon as possible. ... View more

Hello,   Thanks for your inquiry.   Regarding the contact not being added to your account, it would be helpful if you could provide the exact code that you are using in place of "(execute code to add visitor to mailing list and send e-mail)" in your example.  We will do the best we can to troubleshoot the problem within your code.   Also, it appears that you are using the mail function, which is not related to Constant Contact.  The mail function typically works with your own local mail server.  This would explain the SMTP error message that you are receiving.  I would suggest reviewing your mail server settings in order to troubleshoot this error.   Thanks, ...

Hi Jennifer, Sorry for the trouble.  I have a few questions: What is the exact error message that you are receiving? Are you sure that you have updated your password everywhere within your code? Also, could you please email me with your username?  You can send the email to webservices@constantcontact.com. Thanks, ... View more

Hello Suvarna, Thanks for your inquiry. Only one API key will be required.  Each user will be able to access their own account using your one API key. In order to gain access to the scheduling portion of our API, you will need to get in touch with someone on our AppConnect team.  You can do so by sending an email to appconnect@constantcontact.com. The organization information will need to be specific to each user's account.  So, you will need to collect this data on a per-user basis. I hope this is helpful.  Please feel free to reply back if you have additional questions or concerns. Regards, ... View more
