API returns 403 Forbidden - integration broken since ~June 29, 2026

[mariusz-d1]

Bug description

Since approximately June 29, 2026, both integrations stopped working.
All sensors show "unavailable" in Home Assistant.

Root cause

The InPost public API endpoint https://api.inpost.pl/v1/points/{point_name}
now returns HTTP 403 Forbidden when called without authorization.

The data IS available on the InPost website (inpost.pl), but the website
uses an authenticated session — which the integration does not have.

Steps to reproduce

curl -s "https://api.inpost.pl/v1/points/WDZ01BAPP"
Returns: {"status": 403, ...}

Environment

• Integration version: 1.7.0
• Home Assistant: 2025.12.5 (Container)
• Affected points: WDZ01BAPP, KIW01BAPP (likely all points)

Expected behavior

Integration should fetch air quality data from InPost API successfully.

Possible fix

InPost may have restricted public API access and now requires authentication
or a different endpoint. Please investigate if there is an alternative
endpoint or auth method available.

While it's true that the endpoint you provided returns 403 — we don't use it 😅. We use another one (but only during setup) that seems to work fine. I checked machines you mentioned and they are working fine for me.

For POZ02BAPP it doesn't work. That point has air quality available in the InPost app.
