Frequently asked questions
Thomson Reuters Engagement scores F on the API Report Card. No public REST API for Engagement or the CS Professional Suite; the Thomson Reuters developer portal covers other products. Integration is limited to file imports/exports and internal suite links, and any automation means reverse-engineering browser sessions through SSO and MFA.
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.
Thomson Reuters Engagement (Engagement CS / Engagement Manager) is audit engagement and workpaper management software within Thomson Reuters' CS Professional Suite.
Compliance, Typically for small-to-mid-size CPA and accounting firms performing audit, review, and compilation engagements, as well as tax workpaper management. Firms use Engagement daily to assemble audit binders, import and adjust trial balances from GL systems, prepare workpapers and lead schedules, execute PPC/Checkpoint Engage methodology checklists, manage review notes and sign-offs, and collaborate on PBC requests with clients.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial Thomson Reuters Engagement API and MCP server so AI agents and internal tools can read and write Thomson Reuters Engagement data. See the Thomson Reuters Engagement integration docs at supergood.ai/docs/thomson-reuters-engagement-api.
