Oauth Redirects me to sign in page

Oauth Redirects me to sign in page

I am developing a postman script for me to securely get my credentials via Zoho Vault. With that, I need to authorize my postman to be able to access Zoho Vault.

I am currently on Step 1 in this Zoho Vault | API Reference which redirects me to this guide Client-based Apps - Get Access Token | OAuth 2.0 - Zoho.

It says that I need to perform GET with my set of parameters on url https://accounts.zohocloud.ca/oauth/v2/auth (Canada based).

Upon doing so, I receive a response that I'm being redirected to Zoho Login page.

Am I performing GET on the right Endpoint?
