Frequently asked questions
Cumulus Retail scores D+ on the API Report Card. Celerant publishes no general-purpose self-serve API for Cumulus Retail. Integration means a catalog of 150 plus pre-built connectors, SPS Commerce EDI, or custom work by Celerant analysts per customer. Partner docs like Credova's imply an internal API, but it is not openly documented.
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.

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 Cumulus Retail API and MCP server so AI agents and internal tools can read and write Cumulus Retail data. See the Cumulus Retail integration docs at supergood.ai/docs/cumulus-retail-api.
