Why did I get a message that Salesforce API is not enabled with my jotform account?

Also, I got the message that API is not enable for my jotform account. Why is that?

In regards to your question here you are mostly wondering why you are receiving a message that the API is not enabled for your jotform account.

The reason for this message is that our system has detected that you don't have (or are not using) the correct Salesforce Account Type and API hence a warning notice is then displayed.
