Question 1

What can I write to Zendesk?

Accepted Answer

Users, organizations, tickets and Zendesk custom objects. Delete mode exists for users and organizations only, which is a sensible restriction: having a sync delete tickets is almost never what anyone actually wants.

Question 2

How is the matching record found?

Accepted Answer

It depends on the object. Users match on Zendesk ID, email, or external ID. Organizations on Zendesk ID or external ID. Custom objects on Zendesk record ID or external ID. Tickets are the exception worth knowing about: updates match only on the Zendesk ticket ID, and create mode always creates a new ticket rather than looking for an existing one.

Question 3

Can custom fields be written?

Accepted Answer

Their values, yes. Custom ticket fields and custom user fields are both writable through the mapping. What reverse ETL will not do is create or alter the field definitions themselves, so build the field in Zendesk first, then map to it.

Question 4

What happens to rejected rows?

Accepted Answer

A row Zendesk rejects is skipped, counted as an error, and written to the record logs with its identity and the Zendesk error detail. The rest of the batch continues. Rejected rows are not retried automatically, so the pattern is fix and rerun. A request or job level failure is a different case and can fail the batch outright.

Question 5

Why push database data into a support tool?

Accepted Answer

Because the agent needs it at the moment of replying. Plan tier, usage over the last month, an open invoice, a renewal date. Those live in your database and are invisible inside Zendesk unless something puts them there, and asking agents to look them up in another system is exactly where response times go.
