Question 1

What is a Harmonic saved search here?

Accepted Answer

It is a saved query inside Harmonic, not a stored snapshot and not a special record type. Polytomic runs that query at sync time and reads whatever currently matches it, which is why results legitimately change between runs even when you have changed nothing on either side. Only team visible saved searches of the companies or persons type are offered.

Question 2

What can I select?

Accepted Answer

Shared Harmonic lists containing companies, people or investors, plus company saved searches and people saved searches. Older connections expose company and people watchlists separately. Private saved searches, and lists not shared with your team, are deliberately excluded, so when something is missing from the picker, sharing it in Harmonic is almost always the fix.

Question 3

What comes out of a company saved search?

Accepted Answer

Companies, company funding rounds, company highlights, investors, people, person highlights and person education. A people saved search gives you people, highlights and education. Newer Synapse lists carry a single entity type decided by the list itself rather than offering the full spread.

Question 4

Does it read incrementally?

Accepted Answer

No. Every ETL run restarts the saved search or list query and paginates through all the current results. The cursors involved are page cursors within a single run, not checkpoints that persist between runs. Harmonic advertises bulk source mode only, with no incremental reader at all, so size your schedule with that in mind.

Question 5

What does authentication need?

Accepted Answer

An API key from the Harmonic usage dashboard, which Polytomic sends in the apikey header and validates against Harmonic's auth endpoint. There is no OAuth flow. What you can read is bounded by that key's Harmonic subscription, and Deal Data fields need both the API entitlement and the Harmonic Deal Data API option enabled on the connection.
