Persistent 'Invalid Credentials' Error During Upstox Login

Developer API
1

I am encountering a persistent issue when attempting to log in to the Upstox using the redirection login flow. Despite providing correct credentials, I consistently receive the following error after entering the 6-digit PIN on the Upstox login screen.

{“status”:“error”,“errors”:[{“errorCode”:“UDAPI100016”,“message”:“Invalid Credentials”,“propertyPath”:null,“invalidValue”:null,“error_code”:“UDAPI100016”,“property_path”:null,“invalid_value”:null}]}

I have double-checked my credentials, ensured the accuracy of the redirect URI, and verified that the API key and secret are correct. Despite these efforts, the issue persists, and I am unable to log in successfully.

Redirect url : http://localhost:8080/login/callback-upstox/

Please investigate this matter and provide guidance on resolving the ‘Invalid Credentials’ error during the redirection login process.

Thank you for your assistance.

@Yamanrb12,

Thank you for reaching out.

Assuming you are using a browser to authenticate to the API, the error you’re encountering may be related to your browser’s settings preventing the setting of a necessary cookie for the authentication process.

Could you please try using a different browser for this task and let us know if the issue persists?

Thank you!

Hello @shanmu Thank you ,

I attempted the same process in a new incognito window, but encountered the same issue. In the new window, the system prompted me to complete the entire login procedure, including entering my mobile number, TOTP (Time-based One-Time Password), and PIN.

@shanmu Any Update ?

@Yamanrb12,

Please provide your UCC and the URL you’re using to initiate the login. For security purposes, you may omit the client_id when sharing this information.

Thanks!
