Error with NHS Login Sandpit Api returns invalid_client_id

Hi,

I am trying to log into the NHS login in sandpit environment
using below url
https://auth.sandpit.signin.nhs.uk/authorize

This is the response message we get back,

{“error”: “invalid_client_id”, “state”: “db27795ccf2df5d93ec73b57777fae2d327f1048”}

This was working before but has stopped working for a couple weeks now. Do we need a new client ID or has something else changed recently ?

Kind regards,
Lekan Oni

when was the date of your last successful login also maybe you should, the client ID may be expired also Log in to the NHS Login developer portal and check if your client ID is still active and correctly configured

Hi, the last successful login was the last week in August, Is it alright if you could point me in the right place to check whether or not the Client ID has expired ? Our client ID is PHUBIntegrNoGP.
