+Authproxy is part of middleend and it exposes following 3 apis
+1. **/v1/login**
+   - Redirects user to keycloak login page.
+   - Sets a cookie with original URL
+2. **/v1/callback**
+   - After successful login gets auth code and exchange it for token.
+   - Set id_token and access_token in cookie and redirects to original URL
+3. **/v1/auth**
+   - Retrieve idtoken from cookie and verifies the JWT.
+   - If id_token is valid then access to resources else redirects to login page.
+
+Required inputs of authproxy comes from authproxy section of helm config
+- Issuer
+- Redirect URI
+- Client id
