Service and helpdesk marketplaces reach support, IT, and operations teams who live inside a ticketing or ITSM tool all day. Apps that embed context in the agent workspace, automate routine tickets, or sync with CRM and engineering systems directly raise agent productivity — a benefit these buyers measure and pay for.
The typical build is an embedded app inside the agent view (Zendesk’s ZAF, Freshworks’ FDK, ServiceNow’s App Engine) plus connectors and workflow actions against the platform’s REST APIs. Public apps use OAuth 2.0; simpler single-account integrations often use API tokens.
ServiceNow sits at the enterprise, high-compliance end with partner certification and formal security review; Freshworks and Zendesk are quicker to list and skew toward SMB and mid-market support teams. Match your compliance appetite and target company size accordingly.
