Enable JSON-API and add API Secret Key
Go to the Global Configuration > ConvertForms > Advanced Tab. Under this tab, you will see the Enable JSON-API. This option must be enabled.
Next, head over to the Security Tab. Within this tab, you will find the API Secret Key field that is used by Zapier for authentication. This must be an alphanumeric. No specials characters are allowed.
