Use custom login page of my application - Zoho Desk SAML Integration

Hi,

I am currently using Keycloak as an IDP for federated login of a Zoho Desk portal.

Zoho Desk does not allow compatibility with OpenID, for this reason the protocol I use on Keycloak for clients is SAML.

I need to use a custom login page on my host, outside the keycloak environment, which allows me to authenticate and return to my zoho desk portal with already logged in.

I tried to use the Rest API (which seem to work only with the OpenID protocol) receiving access and refresh token but I don’t understand how to send this information to the zoho desk portal to be authenticated.

Any suggestions?

Thanks for the support
