Why teams connect Apollo.io and Notion

Sync what happens in Notion with the customer records in Apollo.io, in real time and in both directions.

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 Users, Comments, Files and attachments, Pages in Notion to People (database records), Sequences, Deals (Opportunities), Tasks and calls in Apollo.io with bi-directional, real-time sync. Activity and record changes in Notion update the matching contact or account in Apollo.io, and CRM data flows the other way wherever Notion can store and use it.

Common use cases

  • 01 Sync a Notion content-calendar database with Jira or Linear by mapping status and date properties both directions.
  • 02 Read Notion wiki Pages and their Blocks into a database or search index for internal knowledge retrieval.
  • 03 Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.
  • 04 Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.

Common sync patterns

Where Notion can store CRM context: fields kept current

Owner, lifecycle stage, or account details from Apollo.io sync into Notion, so people working there have the context without switching tools.

Where Notion supplies contact or company data

Enriched fields land directly on records in Apollo.io, and refreshes keep them from going stale.

What you can sync between Apollo.io and Notion

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.

Apollo.io objects Notion objects How this pairing syncs
Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. 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. Contacts is specific to Apollo.io and Files and attachments to Notion — each maps to any object or custom field on the other side.
Accounts Company records with firmographic attributes, matched to CRM accounts during sync. Pages The core content unit and also every row of a database; synced two-way as records, with typed properties mapping to table columns. Accounts is specific to Apollo.io and Pages to Notion — each maps to any object or custom field on the other side.
People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. 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. People (database records) is specific to Apollo.io and Databases / Data sources to Notion — each maps to any object or custom field on the other side.
Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. 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 is specific to Apollo.io and Properties to Notion — each maps to any object or custom field on the other side.
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. Blocks The page body — paragraphs, headings, to-dos, tables — nested as children and fetched recursively, separate from a page's properties. Deals (Opportunities) is specific to Apollo.io and Blocks to Notion — each maps to any object or custom field on the other side.
Tasks and calls Rep activity records synced for activity reporting and coaching workflows. Formula and Rollup properties Values computed by Notion from other fields; read-only, so they are pulled out for reporting but never written back. Tasks and calls is specific to Apollo.io and Formula and Rollup properties to Notion — each maps to any object or custom field on the other side.

How changes propagate between Apollo.io and Notion

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.

Apollo.io Notion Interval-based propagation

DetectionStacksync polls Apollo.io for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at timestamps.

DeliveryEach detected change is written to Notion through its API, with automatic retries and rate-limit backoff.

Notion Apollo.io Sub-second propagation

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 Apollo.io through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Apollo.io: Rate limits and enrichment credits vary by plan; bulk endpoints are throttled separately from single-record calls.
  • Notion: Average of ~3 requests/second per integration with some bursts; 429 with a Retry-After header when exceeded. Payloads capped at 500 KB and 1000 block elements.
