URL format for objects in different DC

URL format for objects in different DC

Hi there,
I'm currently working on supporting multiple DCs. While everything works as expected, there is one problematic topic - I am displaying a link that user can click and it will open object in Zoho CRM - i.e. Account. So war, I've been using the following format:
  1. https://crm.zoho.<tld>/crm/EntityInfo.do?module=<module>&id=<object ID>
which required from me maintaining a mapping between `location` from the authorization request and `tld` value (i.e. location = `us`, tld = `com`).

Is there any way to avoid maintaining such mapping (`location` to `tld`)? It would be great if `tld` (or even whole CRM domain) could be returned along with `location`, as part of response for authorization request.

If that's not possible, can you please provide a complete list that allows me to map `location` to `tld`? There is such mapping OAuth requests (source) but I want to make sure if it applies to CRM urls as well.

Thanks!
