Invalid Client - Client ID passed does not exist

Invalid Client - Client ID passed does not exist

Hi,

Daniel here. i try to generate an authorization code by following this page Authorization Request - Web Apps - OAuth | Zoho Accounts

https://accounts.zoho.com/oauth/v2/auth?scope=ZohoCRM.users.ALL&client_id=1000.myclientid&response_type=code&access_type=offline&redirect_uri=https://localhost:7195/account/integrations/zoho/tokencallback

I put a dummy client id. but in real i am using the correct client id from my developer page.

But every time i go to the link above,

i will redirected to EU location (which i assume is correct because my account location is in EU) but i keep getting client id passed does not exist.

Please advise maybe there is a mistake i am not aware of.

Thanks,

Daniel
