'API is not enabled for this Organization or Partner' error on Salesforce integration

I am trying to link Jotform to Salesforce. After I put in my Security Token, I get a message saying I do not have access to the API. Do I need to upgrade?

The issue seems to be with your Salesforce login or account. Please note that the Salesforce edition is required to have API access in order to connect to your JotForm. Please check the Salesforce edition that you are using and only Enterprise and higher editions are provided with API access.
