TL;DR: Before setting up your sync, prepare your monday.com board with the right columns for HubSpot data. This page shows you which columns to create for each HubSpot object type.
Why board setup matters
The sync maps monday.com columns to HubSpot properties. If the right columns don't exist on your board, you won't be able to map the data you care about.

Custom properties: your own HubSpot properties appear in field mapping like any other property — create a monday.com column for each one you want to sync.
Common gotchas
Create columns before setting up the sync for the easiest mapping. You can also create a missing column from the field mapping screen with + Add column.
Match column types to property types — a Status column maps well to a HubSpot dropdown; a Numbers column maps to numeric properties
Don't delete the HubSpot Link column. It's created automatically when you activate a sync and links each item to its HubSpot record (each link is stored both in the app and in this column). See The HubSpot Link column
Keep column names clear — "Close Date" is better than "When will it close." Simple names make field mapping easier.
Avoid formula or mirror columns for mapped fields — these are read-only in monday.com and can't be written to when data flows from HubSpot. Use native column types instead.
