Zoho's own apps integrate cleanly: if you run Zoho Books or Zoho Desk alongside Zoho CRM, we've gone through what their native connections actually sync and where they stop → and the Zoho Desk side of the same story →. Outside the Zoho family, Zoho's Marketplace lists real connectors for Mailchimp, Slack, LinkedIn, and a handful of other external tools, each syncing a defined slice of data, usually contacts and basic activity, between the two systems.
Beneath the named connectors, a steady stream of real searches point at a narrower, more mechanical need: moving contacts and leads in or out of Zoho CRM specifically, syncing with Google Contacts, exporting to Excel, pulling records through the contacts API directly. These aren't full "integration" projects in the Marketplace sense; they're genuine automation-intent tasks that just happen to be smaller in scope.
