Two-way sync
Changes in Affinity or Monday instantly reflect in both systems. No stale data, no manual imports.
Keep Affinity and Monday in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Monday holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.
Stacksync connects Groups, Updates, Users, Workspaces in Monday to Opportunities, Field Values, Notes, Interactions in Affinity with bi-directional, real-time sync. Activity and record changes in Monday update the matching contact or account in Affinity, and CRM data flows the other way wherever Monday can store and use it.
Owner, lifecycle stage, or account details from Affinity sync into Monday, so people working there have the context without switching tools.
Tickets and conversations attach to the right contact and account in Affinity, so sales sees open issues before the next call.
Enriched fields land directly on records in Affinity, and refreshes keep them from going stale.
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Affinity objects | Monday objects | How this pairing syncs | |
|---|---|---|---|
| Field Values Custom field data, either global or scoped to a list, mapped field-by-field in syncs. | Items Rows within a board and the primary record; synced two-way and created, updated, archived, or deleted via GraphQL mutations. | Field Values is specific to Affinity and Items to Monday — each maps to any object or custom field on the other side. | |
| Notes Meeting and call notes synced for record-keeping in other systems. | Subitems Nested rows under items, stored on a separate hidden board; synced as a child table linked to the parent item. | Notes is specific to Affinity and Subitems to Monday — each maps to any object or custom field on the other side. | |
| Interactions Automatically captured emails and meetings, read for activity reporting. | Column values Typed fields (status, date, people, numbers, connect-boards); polymorphic JSON usually written together via change_multiple_column_values. | Interactions is specific to Affinity and Column values to Monday — each maps to any object or custom field on the other side. | |
| Reminders Follow-up tasks associated with people and organizations. | Groups Named sections that group items inside a board; synced as a grouping attribute or category field on the row. | Reminders is specific to Affinity and Groups to Monday — each maps to any object or custom field on the other side. | |
| Lists Pipelines (deal flow, fundraising, portfolio) that structure most Affinity data; syncs usually target a specific list. | Updates Comment and activity threads attached to items; read out into a database for reporting or written back as notes. | Lists is specific to Affinity and Updates to Monday — each maps to any object or custom field on the other side. | |
| List Entries The membership of a person, organization, or opportunity on a list, carrying its list-specific fields. | Users Account members referenced by people columns; read to resolve owner and assignee IDs to names and emails. | List Entries is specific to Affinity and Users to Monday — 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.
DetectionAffinity notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, supplemented by polling.
DeliveryEach detected change is written to Monday through its API, with automatic retries and rate-limit backoff.
DetectionMonday notifies Stacksync of record changes through webhook events. Board-scoped webhooks (create_item, change_column_value, item_deleted, and similar) for real-time events.
DeliveryEach detected change is written to Affinity through its API, with automatic retries and rate-limit backoff.

Yes. Stacksync provides a managed, real-time two-way integration between Affinity and Monday: authenticate both systems, choose the objects to sync (such as Affinity's Field Values and Notes), map fields visually, and changes propagate both ways in milliseconds — no code required.
On the Monday side: Groups, Updates, Users, Workspaces, plus custom fields where Monday exposes them. On the Affinity side: Opportunities, Field Values, Notes, Interactions. Stacksync auto-detects both schemas and converts types between the two systems.
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
Common patterns for Affinity and Monday: Where Monday can store CRM context: fields kept current; Where Monday handles support or shared inboxes; Where Monday supplies contact or company data. Owner, lifecycle stage, or account details from Affinity sync into Monday, so people working there have the context without switching tools.
Affinity: REST API. Authentication: API key. Monday: GraphQL API (single endpoint, api.monday.com/v2). Authentication: OAuth 2.0 for installed apps, or a per-user personal API token (admin/member scope); a date-based API version is sent via request header. Stacksync manages authentication, retries, and rate limits on both sides.
Monday: Rate limiting is complexity-based, not request-count based: each query has a complexity cost capped at 5M per call and ~10M per minute per user token (1M on trial/free). Affinity: The data model centers on lists: a person, organization, or opportunity gains list-specific field values only through its list entry, so syncs must address both the entity and the entry. Stacksync's field mapping accounts for these differences between Affinity and Monday without custom code.
