I am unable to add custom fields using API. I am getting below errors.
json.regex.mismatch.custom_fields:#/custom_fields/0/name: This attribute value must be of the format 'CustomFieldNN' using API
Here is my Sample code to add custom fields.
CTCT.Components.Contacts.CustomField CustomField1 = new CTCT.Components.Contacts.CustomField();
CustomField1.Name = "Department";
CustomField1.Value = "Department 1";
CTCT.Components.Contacts.CustomField CustomField2 = new CTCT.Components.Contacts.CustomField();
CustomField2.Name = "Subject";
CustomField2.Value = "Test Subject";
Please help me.
Thank you for reaching out to Constant Contact's API Support.
The current version of our API is using and older version of the contacts system compared to what is available in our website UI. This means that the API does not currently support custom names when using the custom fields. You will need to use the naming structure of CustomFieldn. You can reference the below link for the differences between the API and the website.
