# Zendesk

Connect Zendesk with a subdomain, email address, and API token. The source writes 43 core and child tables plus discovered custom fields under `titan.zendesk`.
## Connect Zendesk

1. Open **Apps**, choose **Connect app**, and select **Zendesk**.
2. Enter a subdomain, email address, and API token.
3. Review the tables, then save the source.
4. Watch **Sync history** until the first run completes.

Credentials are stored as secrets. They never become lake columns or appear in query results.

## Sync behavior

Ticket, user, and organization custom fields become columns. Tags, comments, attachments, identities, and domains remain queryable child tables.

A new source syncs when you connect it and then follows its schedule. The default recurring interval is 4 hours. An interrupted run keeps its completed progress and retries safely.

Every lake table also has the [system columns](/v2/docs/concepts/your-lake#the-system-columns) `_synced_at` and `_deleted`; the column reference below lists source columns only.

## Table reference

Supernova discovers this reference from the connected account. Zendesk field APIs supply tenant-specific custom columns. The Tables tab shows the resulting core, child, and custom-field reference.

Open **Apps → Zendesk → Tables** after the first discovery run to see every exact table name, column name, type, and sync selection. Dynamic fields cannot be listed truthfully before an account is connected.

## Deletes and history

Rows are merged by their source key. When the source can prove that a row was deleted, Supernova keeps the row and sets `_deleted` so queries can choose whether to include history. Filter current-state queries with `where not _deleted`.
