Using the plugin on a Multisite + multilingual setup

Greetings, I would like to ask some advices about the Zendesk Guide solution. My company and I are working on with WordPress for a project (multilingual and multisite). We would like to use the SSO service of this plugin to connect to it. As we have a multisite installation, each one of them has its own domain name. One per country (and using subdomains for the many languages within the country) We’re seeking a way to setup this connection , so to use many callbacks url, binded to the current site (among the multisites) the user is visiting, to handle the user connection properly. Do you have any strategies, solutions provided to achieve that ? Thanks in advance. PS : I’m also reachable on this mail : ismael@sleede.com Best regards, Ismaël
