HubSpot will sunset its Pipelines API v1 on December 4, 2026. Integrations still calling it need to move to a 2026-03 or newer version of the Pipelines API.

What happened

HubSpot announced on August 14, 2026 that the Pipelines API v1 will be sunset on December 4, 2026.

HubSpot recommends migrating to the Pipelines API 2026-09 version, auditing code for any v1 pipeline calls, and finishing the move well before the deadline. Versions 2026-03 and newer are supported.

Why it matters

Deal and ticket pipeline syncs in older custom integrations and middleware often still use v1 endpoints. Those calls will fail after December 4.

Search your code and your automation platform scenarios for /crm-pipelines/v1/ before the deadline.
