List all mails by mail-adress

List all mails by mail-adress

Hi,

in our admin portal we now want to list all mails of a customer from the support portal, so best the complete dialogue between the customer and the support employee. 

But I can't find my way around the API-Doku https://desk.zoho.com/DeskAPIDocument, there is neither an entity "Customer" to find out a possible customer ID via e-mail address, nor an entity "Mails" to read all mails by customer ID.

Is this documentation the right one for the support system at all?

Thank you!
