Are you seeing this error in your Sync Details Report?
"does not support full HTML or Script Content"
How do I fix this error? Error on sync: Constant Contact error: Contact Data, line: 207, email: [firstname.lastname@example.org], error: addresses/0/city: Field does not support full HTML or script content.
https://api.constantcontact.com/v2/activities/addcontacts (HTTP Status Code: 400)
Thanks and certainly.
Please locate the email above and remove the HTML code from their Address City field in CRM then try to sync again.
Constant Contact does not allow code to sync over.
