**SmartThings Community 2.0.40 — 403 Forbidden after November 2026 API changes (diagnostic results included)
**
@Adrian_Rockall

Hi Adrian,

I’m having trouble reconnecting the SmartThings Community app (version 2.0.40) on my Homey Pro following Samsung’s recent API changes.

I’ve subscribed to the new SmartThings developer plan and generated a fresh Personal Access Token with the permissions specified in the app’s documentation.

When I enter the token during pairing, I immediately receive Error: 403 Forbidden, before reaching the OAuth authorization screen.

I’ve performed three direct API tests using the same token:

  • GET /v1/devices → 200 OK

  • GET /v1/apps → 403 Forbidden

  • GET /v1/smartapps → 200 OK

The device endpoint successfully returns my Brilliant smart panel devices, confirming that the token is valid and can access my devices.

Given Samsung’s recent migration from /v1/apps to /v1/smartapps, I’m wondering whether version 2.0.40 still calls the legacy endpoint during the initial pairing or OAuth setup.

Could you confirm whether this endpoint is used and whether a compatibility update might be necessary?

This integration previously worked well for controlling my Brilliant lighting loads through Homey Flows and Apple Home via HomeKitty.

I look forward to hearing back… and thank you very much for your work on this app!

I will need to check as it’s been a while since I worked on the app due to Samsung’s policy changes. I have basically dropped all my SmartThings devices and only have my washing machine left.
If I can update the app to make it work with paid PATS I will, but I don’t intend to pay for one myself, so I’m not sure how I will test it.

I totally understand what you are saying. Honestly, this might be the excuse i need to disconnect myself from SmartThings. I have only been using it as a bridge between my Brilliant Smart Panels and Homey. It may be time to move on. Thanks for your reply!

I’m withdrawing SmartThings Community from the Homey App Store because new installations can no longer complete authentication following Samsung’s API changes.

I have replaced all my SmartThings devices as I don’t want to pay to be able to use them when there are plenty of free to use alternatives on the market. So, as I have no way to test any changes to try and make the app work again, I don’t feel it is practical to try.

Existing installations may continue working while their OAuth access remains valid, but future operation cannot be guaranteed. Please do not uninstall the app, remove working devices, or run Repair, as reconnecting may fail.

I will no longer be maintaining or supporting the integration. Thank you to everyone who has used and supported it.
