Issue with OAuth Web Server Flow - 'Sorry, there is a problem with the service'

API Issues
1

We have successfully created an application with Companies House and generated a Web key to access the APIs.
However, when initiating the OAuth web server flow using our Client ID, we are encountering the following error: “Sorry, there is a problem with the service.”

We have reviewed similar issues discussed in the forum (URGENT - Not able to connect to the API ), but unfortunately, we have not been able to resolve the issue.

Below is the requested user authorization URL for your reference:

Could you please assist us in troubleshooting this issue?

Thank you for your help.

Thank you,

After calling the OAuth2 endpoint in the sandbox environment, I was redirected to the Companies House sign-in page. Since I didn’t have an account initially, I created one using GOV.UK One Login.

URL : ‘Sign in to Companies House - Companies House - GOV.UK’.

However, when I tried to sign in, I encountered the following error:

Error: There is no Companies House account that uses this email address.

Could you please look into this and advise on how to resolve the issue?

Best regards,

Hi Prashant,

Just wanted to check if you have a breakthrough on this since we are facing the same issue(in LIVE and not sandbox) since March 2025. Your help is much appreciated.
