I am using the Mautic API for adding contacts to my list. It was working previously but not working now. All other API methods are working except add contact method. I received error as **“# This form should not contain extra fields”**. Does anyone has faced the same issue? Any solution on this ? ---

I just ran into this. For me it was because I was including custom fields in my API call that I hadn’t added to Mautic yet.
