HubSpot announced at Fall Spotlight 2026 the end of support for v1-v3 APIs, legacy public apps, and legacy private apps, all with a September 2027 enforcement date. This is a sweeping deprecation affecting a large portion of the HubSpot API surface.

Migration: Audit all integrations using v1-v3 APIs, legacy public apps, or legacy private apps and migrate to current supported versions (date-based versioning, Developer Platform Projects) before September 2027.

HubSpot has added a new changelog entry announcing that Pipeline and pipeline stage delete endpoints will validate references by default starting with the 2026-09 API version (live September 8, 2026). This is a breaking change affecting integrations that delete pipelines or pipeline stages without first removing associated references.

Migration: Review any integration logic that calls pipeline or pipeline stage delete endpoints and ensure all references (e.g., deals linked to pipeline stages) are removed or migrated before deletion, prior to adopting the 2026-09 API version.
