| Monday objects | Twenty CRM objects | How this pairing syncs | |
|---|---|---|---|
| Updates Comment and activity threads attached to items; read out into a database for reporting or written back as notes. | Attachments Files linked to records. | Updates is specific to Monday and Attachments to Twenty CRM — each maps to any object or custom field on the other side. | |

| Boards Table-like containers that hold items; each board maps to a synced table, and its columns define the field mapping. | Companies Account-level records that group people and opportunities. | Boards is specific to Monday and Companies to Twenty CRM — each maps to any object or custom field on the other side. | |
| Items Rows within a board and the primary record; synced two-way and created, updated, archived, or deleted via GraphQL mutations. | Opportunities Deal records tracked through pipeline stages, synced for forecasting. | Items is specific to Monday and Opportunities to Twenty CRM — each maps to any object or custom field on the other side. | |
| Subitems Nested rows under items, stored on a separate hidden board; synced as a child table linked to the parent item. | Tasks To-dos linked to people, companies, or deals. | Subitems is specific to Monday and Tasks to Twenty CRM — each maps to any object or custom field on the other side. |
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Authentication: API key. Stacksync manages authentication, retries, and rate limits on both sides.
Monday: The API is GraphQL-only; item queries use cursor-based items_page pagination capped at 500 items per page, so large boards are read with a cursor. Twenty CRM: Twenty is open source and self-hostable, backed by PostgreSQL, with an object and field model that is metadata-driven and editable from the UI.
