How Knit builds this workflow

Common questions
Can Knit build “Segment contacts based on custom database query results” between PostgreSQL and Poplar?
Yes — describe it in the box above and Knit's Integrations Agent researches PostgreSQL and Poplar's public API docs (or your own uploaded docs) and builds a working workflow, whether or not either app already has a pre-built connector.
How long does it take to build?
Minutes to a first working version, not weeks — you test it against real data before it goes anywhere near production.
What's the most common Databases & Warehouses + Marketing automation?
Syncing campaign and contact activity from Poplar into PostgreSQL on a schedule, so marketing metrics can be joined against product or sales data.
Does this need a specific reporting format?
No — the Agent maps Poplar's own fields into whatever table structure PostgreSQL expects, so it fits your existing schema rather than forcing a new one.
