property found but not permitted at this location

I received an email from our CC contact form but the new contact is not successfully added to our specified list.  

Looking at the logs it appears this has happened in the past. 

Here is the recent log error.

Please note, there are no custom fields - Just first name, last name and email.

Hello SabrinaD460,


Thank you for reaching out to Constant Contact API Developer Support. My team is here to assist outside software developers with questions about building into Constant Contact's API.


I'm sorry to hear that you are having list addition issues with your sign-up form. It looks like you are using the integration “Constant Contact Forms for WordPress”, which was developed by and is directly supported by Constant Contact, so I’m going to escalate this case to one of our Tier 2 support specialists so that they can follow up directly for further troubleshooting. 


They should be in touch within 4 business days. Otherwise, for immediate assistance, or if you’d like a callback/email from them at a certain day/time you can call our support line at 866-289-2101 and reference case #29496120.


Courtney E.
Tier II API Support Engineer
