HubSpot API changes & breaking changes
CRM integrations outlive the people who wrote them: contacts, companies, and deals syncing into billing, support, and data warehouses. Detektu diffs HubSpot's published CRM contracts so an object schema change becomes a finding before it becomes a broken sync.

How HubSpot ships changes
The release patterns that shape your integration risk.
HubSpot publishes OpenAPI contracts for its CRM APIs: core objects, properties, pipelines, lists, owners, and the v4 associations model. The surface evolves steadily, and sync code written against v3 objects tends to run unattended for years.
Detektu watches each contract separately and names the exact object API and property that changed, so you can match findings against the objects your sync actually reads and writes.
From change to finding

Illustrative examples. Every real finding carries exact before/after evidence, severity, and source provenance.
