Two-way sync
Changes in Notion or Outreach instantly reflect in both systems. No stale data, no manual imports.
Keep Notion and Outreach 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 Notion 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 Formula and Rollup properties, Users, Comments, Files and attachments in Notion to Tasks, Opportunities, Users, Mailboxes in Outreach with bi-directional, real-time sync. Activity and record changes in Notion update the matching contact or account in Outreach, and CRM data flows the other way wherever Notion can store and use it.
Enriched fields land directly on records in Outreach, and refreshes keep them from going stale.
Owner, lifecycle stage, or account details from Outreach sync into Notion, so people working there have the context without switching tools.
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.
| Notion objects | Outreach objects | How this pairing syncs | |
|---|---|---|---|
| Users Workspace members and bots referenced by people properties; read-only — users cannot be created or invited through the API. | Users Seat holders used to resolve ownership on synced records | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Files and attachments File-property and file-block values. Notion-hosted URLs are temporary and expire, so files are re-fetched or copied at sync time. | Mailboxes Connected sending accounts referenced when attributing outbound activity | Files and attachments is specific to Notion and Mailboxes to Outreach — each maps to any object or custom field on the other side. | |
| Pages The core content unit and also every row of a database; synced two-way as records, with typed properties mapping to table columns. | Prospects The people being engaged; the main record kept in sync with the CRM | Pages is specific to Notion and Prospects to Outreach — each maps to any object or custom field on the other side. | |
| Databases / Data sources Collections of pages with a typed property schema. Since the 2025-09-03 API a database is a container holding one or more data sources; syncs target a specific data_source_id. | Accounts Companies grouping prospects, aligned with CRM account ownership | Databases / Data sources is specific to Notion and Accounts to Outreach — each maps to any object or custom field on the other side. | |
| Properties Typed columns on a page — title, rich_text, number, select, multi_select, date, people, relation, status, checkbox, URL. Read and written both ways. | Sequences Multi-step cadences; synced as reference data for enrollment automation | Properties is specific to Notion and Sequences to Outreach — each maps to any object or custom field on the other side. | |
| Blocks The page body — paragraphs, headings, to-dos, tables — nested as children and fetched recursively, separate from a page's properties. | Sequence states Per-prospect enrollments; writing one adds a prospect to a cadence | Blocks is specific to Notion and Sequence states to Outreach — 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.
DetectionNotion notifies Stacksync of record changes through webhook events. Workspace webhooks (page.created, page.content_updated, data_source.schema_updated, comment.created.
DeliveryEach detected change is written to Outreach through its API, with automatic retries and rate-limit backoff.
DetectionOutreach notifies Stacksync of record changes through webhook events. Webhook subscriptions on resource create, update, and destroy events, plus polling.
DeliveryEach detected change is written to Notion through its API, with automatic retries and rate-limit backoff.
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Notion–Outreach connection.
Changes in Notion or Outreach instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Notion or Outreach data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Notion or Outreach record.
Track your Notion ⇄ Outreach sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Notion and Outreach.
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate Notion and Outreach with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Notion and Outreach objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Notion and Outreach: authenticate both systems, choose the objects to sync (such as Notion's Users and Files and attachments), map fields visually, and changes propagate both ways in milliseconds — no code required.
Change detection on Notion: Workspace webhooks (page.created, page.content_updated, data_source.schema_updated, comment.created; HMAC-SHA256 signed) plus polling on each page's last_edited_time. On Outreach: Webhook subscriptions on resource create, update, and destroy events, plus polling. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
On the Notion side: Formula and Rollup properties, Users, Comments, Files and attachments, plus custom fields where Notion exposes them. On the Outreach side: Tasks, Opportunities, Users, Mailboxes. 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 Notion and Outreach: Where Notion supplies contact or company data; Where Notion can store CRM context: fields kept current. Enriched fields land directly on records in Outreach, and refreshes keep them from going stale.
Notion: REST API (api.notion.com/v1). Authentication: OAuth 2.0 for public integrations, or an internal integration secret (bearer token); every request must send a Notion-Version header. Outreach: REST API conforming to the JSON:API specification. Authentication: OAuth 2.0. Stacksync manages authentication, retries, and rate limits on both sides.
