A commercial sales CRM that’s been widely adopted by nonprofits, the plugin- and customization-friendly Salesforce underlies a variety of setup configurations including but certainly not limited to Nonprofit Success Pack (NPSP), Pardot (a marketing automation extension of Salesforce), the cloud-based On-Demand Sandboxes (ODS), as well as the now-deprecated configurations Luminate CRM (LCRM) and NGO Connect (NGOC).
Under any name, Salesforce boasts robust APIs that are just perfect for bots.
