Unable to log in to the SmartThings Developer Center

Hi everyone,

I am having trouble logging in to the SmartThings Developer Center and was wondering if anyone else is experiencing the same issue or knows a solution.

Here are the details of my situation:

  • Issue: Cannot log in via both Samsung and Google accounts.

  • Observation: Logging in to the official Samsung website works perfectly fine, but it fails only on the Developer Center page.

  • Error: I have attached a screenshot of the error message that appears during the login attempt.

I have already tried clearing my browser cache and using a different browser, but the problem persists. Any advice or help from the community or the support team would be greatly appreciated.

Thank you in advance!

Hi, @yeosu0107
Are you still having issues with the Developer Console? I was able to enter now, it might have been a temporary issue
Since your post was flagged as Spam, it’s been a while since you reported it and I approved it.

Unfortunately, I still can’t seem to log in. Since this is my very first time trying to access the SmartThings Console, could there be an issue with my account itself?

Could you try accessing the Developer Center using an incognito/private browsing window and let us know if the issue persists there?

The login issue persists even in Incognito mode.
Currently, I am able to log in via SmartThings. Add a little smartness to your things. and am working through the CLI, but I will eventually need access to the console for long-term use.

Should I provide the network traffic logs to help with the investigation?

Could it be an issue with Google account being enabled. I have seen a couple of users post about being denied access to my.smartthings.com in the past. To fix, they would login to https://account.samsung.com, open their profile and disable Google account. they could then login to my.smartthings.com. after that they enabled Google account in their Samsung account and all was good. Just a thought but i could be totally off on this.

Anyway, the OP should wait on your thoughts before proceeding. I don’t want to cause any harm if I am wrong.

Hi,
Yes, could you please share the network traffic logs you mentioned? Additionally, it would be very helpful if you could include the exact timestamps (with your timezone) when the issue occurred.

@Itati
Sorry for the late response.

The following 2 APIs keep returning 302: https://account.samsung.com/api/auths/, https://account.smartthings.com/ssoCallback?

I have removed some information such as authcode as it appears to be personal/sensitive data.

All other SmartThings-related services are working fine with login, but I’m unable to log in to the console specifically.

Additionally, on the SmartThings Developer Center landing page, the following API is consistently returning 401: https://developer.smartthings.com/api/client/pastora/organizations

Is there any separate setup or permissions that need to be granted before logging into the console?

Additionally, when calling https://account.samsung.com/api/auths/~ directly in the browser, it seems the following message is displayed.

``{"error":{"code":"NotFound","message":"The key is invalid.5YyfdaWlHfMPJ7oIau"}}``

Thank you for the information shared so far.

To continue the investigation, could you please provide the exact timestamps (including your timezone) when the issue occurred?

If you don’t remember the timestamps, please reproduce the issue again and share the new timestamps with us.

Additionally, could you please grant impersonation access to your account so our engineering team can review some details?

  1. Confirm the email account registered in the forum is the same one you use for SmartThings. If not, please share it with me over DM.
  2. Enable support access to your account:
  1. Go to the SmartThings Web (my.smartthings.com)
  2. Log in to your Samsung Account
  3. Select Menu (â‹®) and choose Settings
  4. Toggle on Account Data Access
  5. Select the time period and confirm - In this step, please select “Until turned off”, once the team finishes, we’ll let you know so you can disable it again.

More info about this access here: https://support.smartthings.com/hc/en-us/articles/36170233944852-Enabling-Account-Data-Access-for-Support

Thank you very much for the detailed guidance.

I have activated Account Data Access, and the email address is the same as the one used for the community.
Since there was no previous timestamp, I have just tried again.
