To directly connect with Salesforce, you will need a Salesforce account that includes the Web Services API. Currently, this includes the following Salesforce plans: Enterprise, Performance, or the Professional edition with the optional Web Services API upgrade. Here are the various plans Salesforce offers.
DataHero uses the Salesforce Web Services API to connect to your Salesforce account directly and this is why a certain Salesforce plan is required. Should you have questions on these plans, please contact Salesforce for more information on upgrading to a plan that includes the Web Services API.
