HubSpot will sunset the Pipelines API V1 on December 4, 2026. After this date, the API will no longer be supported. If your integration relies on V1 endpoints, you'll need to migrate to the 2026-03 or newer version before the deadline to avoid disruption.
What's Changing
The Pipelines API V1 is being permanently retired. Any calls to V1 endpoints will stop working after December 4, 2026.
We recommend migrating to the Pipelines API 2026-09 version, which becomes generally available on September 9, 2026 and is the latest version of this API. Review the linked API reference to understand the updated endpoints, request/response shapes, and any behavioral differences that may affect your integration.
We recommend auditing your codebase for any V1 Pipelines API calls and completing your migration well ahead of the December 4 deadline.
When is it happening?
This API will sunset on December 4, 2026. V1 endpoints will stop responding after this date.
