SCORECARD

ExistenceGOODA REST API is real and in production, posting invoices, payments, and PO status to cloud ERPs without middleware.
AccessPOORNo self-serve path; access is gated through Stampli's integrations team, partner onboarding, or customer implementations.
CoveragePOORThe API is shaped for ERP sync of invoices, payments, and PO status; no general-purpose surface is exposed to third parties.
AuthPOORNo public authentication documentation exists; the scheme is shared only during a partner implementation.
Docs & DXPOORNo developer portal exists; webhooks, rate limits, error codes, and sandbox details are undocumented publicly.
StabilityMIXEDSync cadences are documented, roughly 2-hour master data and 5-minute downstream, but versioning and deprecation are not public.
Supergood: Stampli has an API, but using it means gates, contracts, or workarounds. Ours doesn't: stable endpoints, normalized JSON, managed auth.
