Steps
Confirm which API surface applies: docs.grassfish.com/grassfish-api lists three current products — the IXM One API, a separate Ad Booking API for retail media, and the newer IXM Aqua API (cloud-native platform announced 2025)
Sign up or log in to the Document360-hosted developer portal (docs.grassfish.com) — the full API reference pages require an authenticated account and redirect to identity.document360.io if not logged in
Request platform/API credentials through Grassfish's commercial onboarding (grassfish.com or a sales contact), since public self-serve API keys are not offered
Use the IXM One/IXM Aqua API to manage content objects such as categories, locations, and media groups in the signage CMS
Use the separate Ad Booking API for programmatic/retail-media ad booking workflows within IXM
Known gotchas
Full API reference content is gated behind a Document360 login (docs.grassfish.com/apidocs/overview redirects to identity.document360.io) — exact endpoint paths and auth scheme could not be verified without an account
Grassfish has platform-naming churn: legacy 'IXM One' vs. newer 'IXM Aqua' (built on Visual Art's Signage Player, AI-driven, API-first) appear to be distinct API surfaces — confirm which generation a target customer is on before integrating
Grassfish is not renamed as a brand, but it has been a subsidiary of Vertiseit AB (Swedish-listed) since 2021 — don't confuse the corporate parent (Vertiseit) with the product/docs brand (Grassfish/IXM)
