I tried adding a comment to this topic but it was ignored, so I'm creating a separate topic.

When using GET /api/v1/contacts and /api/v1/accounts, many fields are not returned, including address/zip/state information and all custom fields. My use case involves syncing data from an external database to Zoho Desk, and right now the only way to keep the information updated involves making a PATCH every day for each of our thousands of contacts/accounts. If the "List" feature returned custom fields and address fields, I'd be able to limit my PATCH activity to the records where the external database and the Zoho data don't match. But for now, I have no way of knowing whether the data matches without making thousands of GET calls.

Your response to the initial ticket said that custom fields would be available in the "List" feature in the "near future". That was 11 months ago. Is there any update?
