Salesforce says their extra API service is required to use the RingCentral app with Salesforce Professional. Is it? App docs don't say.

For this inquiry, please contact the developer support team via email or creating a support ticket.

Hi Lorie,

According to our requirements for the Salesforce app (https://developers.ringcentral.com/app-gallery.html#/app/salesforce):

• RingCentral for Salesforce is available for RingCentral Office Premium and Enterprise customers.
• You must have a Salesforce Professional, Enterprise or Unlimited Edition account.
• Requires Windows XP or above or Mac OS X 10.8 Mountain Lion or above.
• Supported browsers include: ChromeTM 30 (or later), Firefox 25 (or later), Safari 6.0.5 (or later), and Internet Explorer 10 (or later).

According to Salesforce (https://help.salesforce.com/HTViewSolution?id=000005140&language=en_US):

• Salesforce Editions which have API access enabled by default
• 1. Enterprise Edition
  2. Unlimited Edition
  3. Developer Edition
  4. Performance Edition

The reason we say that Professional Edition is the minimum requirement is because you can purchase the extra API services (per the above URL):

*Professional can have API Temporarily turned on by contacting their Account Executive.  Professional can also purchase API by contacting their Account Executive.
