Gainsight API
Gainsight documents REST APIs for NXT and a separate PX API, plus an async CSV Bulk API, but there is no unified developer portal. Auth is tenant-specific access keys issued by an admin, with no OAuth. Rate limits are documented and tight: 100 sync calls per minute, 50,000 per day.
Frequently asked questions
Gainsight scores D on Supergood's API Report Card. Gainsight documents REST APIs for NXT and a separate PX API, plus an async CSV Bulk API, but there is no unified developer portal. Auth is tenant-specific access keys issued by an admin, with no OAuth. Rate limits are documented and tight: 100 sync calls per minute, 50,000 per day.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Gainsight is a customer success and product experience software company headquartered in San Rafael, CA, founded in 2009.
Vertical: Customer Success / Post-Sales Operations / Product Experience SaaS. Customers use Gainsight CS as the system of record for post-sales customer data: ingesting account/usage/support/billing data via connectors and APIs, computing customer health scores, generating CTAs (risk, expansion, lifecycle) routed to CSM playbooks, managing renewal forecasts and Success Plans, running NPS/CSAT programs, and reporting on retention/expansion metrics to executives.
8/10. Gainsight is widely regarded as the category-defining customer success platform and the de facto enterprise standard.
Gainsight holds the system of record for post-sales customer health: account-level revenue/ARR, renewal dates, contract metadata, usage telemetry, NPS/CSAT survey responses, CTA history, CSM activity logs, support ticket aggregates, and email/call engagement data.
Founded in 2009 (originally JBara Software, rebranded Gainsight 2013). Acquired by Vista Equity Partners in 2020 for ~$1.1B.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Gainsight scores GOOD on MCP availability. Gainsight ships an official Gainsight CS MCP server, hosted per tenant at gainsightcloud.com, with OAuth setup and connection steps for Claude, ChatGPT, and Copilot Studio documented on its support site. Its Staircase AI product also has an official MCP server listed in Claude's connector directory.
Yes. Gainsight publishes an official MCP server, so MCP clients like Claude, Cursor, and Codex can connect to it directly. Setup instructions are in the vendor's documentation.
