UDAPI100016 error

Developer API

I am trying to generate the Authentication code which is required to generate the Access Token, but as soon as i enter my pin on the login page, it gives UDAPI100016 error saying invalid credentials.

Here is the full error

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

The initial step to send a request to “https://api.upstox.com/v2/login/authorization/dialog” works fine and I get the login page but when i enter my pin, it will show above error, I have cross checked all my credentials and they are correct.

Please help me out
My Dep UCC is 12081801 and my UCC is 3JCQED
and my redirect_uri is “https://localhost:8000”

We will check with the relevant team and get back to you. In the meantime, could you confirm if you are using the mobile number 9*******29? This issue may occur if you are using a different mobile number than the one associated with the account where the app was created.

Yes, I am using the same mobile number.

I think the url now gives me the auth code, although the sign in doesn’t happen, thanks
