HubSpot API breaking changes (2025–2026): complete tracker and fixes

hubspot 3 breaking / deprecation entries 2025–2026

HubSpot ships API and SDK changes continuously. Most are additive — but the ones that are not can silently break integrations that worked yesterday. This page is the complete, continuously regenerated record of every HubSpot breaking change and deprecation in the mendapi change database: 3 entries (3 breaking, 0 deprecation), each linked to its upstream source and, where possible, to a concrete fix.

How to read this page

Every entry carries a fixability verdict from the mendapi adjudication pipeline: code-fixable means a mechanical code change repairs the break (1 entries); not code-fixable means the change requires a business decision, credential provisioning, or upstream action that no codemod can produce (2 entries). Entries marked auto-fix pack have a deterministic, gold-tested migration pack that mendapi fix can apply locally.

Am I affected?

Reading a changelog tells you what changed — not whether your code uses the affected surface. The mendapi scanner answers that locally, in about 30 seconds, without any code leaving your machine:

npx mendapi sync
# -> one network call: pulls the change feed into a local database
npx mendapi scan
# -> N findings: file, line, provider, confidence
mendapi deps --match
# -> which of the changes below actually hit your endpoints

See Getting Started for the full workflow and the security model for why zero code upload is the default and only mode.

Recent HubSpot releases adjudicated non-breaking

Not paging you is the other half of the job. The same pipeline that produced the timeline above also cleared 7 HubSpot changes as additive or fix-only — releases an integrator can upgrade through without a migration. The most recent:

Monitoring HubSpot going forward

This page is regenerated from the change database, which is fed by release feeds, changelog capture and OpenAPI spec diffing — so it does not depend on HubSpot writing a perfect changelog. mendapi monitors 84125 change records across 20 providers; hosted plans watch your repos continuously and open fix PRs when a change lands.

Frequently asked questions

How do I check if my codebase is affected by HubSpot breaking changes?

Run npx mendapi scan in your repo. It statically matches your files against the 3 HubSpot breaking changes and deprecations in this tracker and reports file, line and confidence for every hit — locally, in about 30 seconds, with zero network calls.

How many HubSpot API breaking changes are on record?

This tracker records 3 entries for HubSpot (3 breaking changes and 0 deprecations, 2025–2026). Each entry is adjudicated: 1 is code-fixable, 2 require a decision no codemod can make.

Are there automated fixes for HubSpot breaking changes?

Yes — mendapi ships 1 deterministic migration pack for HubSpot. mendapi fix applies them locally as reviewable diffs; every pack is gold-tested and idempotent.

Does my code get uploaded when scanning for HubSpot changes?

No. mendapi scan, deps and fix run with zero network code, mechanically enforced by the test suite. Optional hosted reporting is metadata-only, secrets-redacted, and requires an explicit flag.
