Why teams connect Apollo.io and Monday

Sync what happens in Monday 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 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 Users, Workspaces, Boards, Items in Monday to People (database records), Sequences, Deals (Opportunities), Tasks and calls in Apollo.io with bi-directional, real-time sync. Activity and record changes in Monday update the matching contact or account in Apollo.io, and CRM data flows the other way wherever Monday can store and use it.

Common use cases

  • 01 Two-way sync of Items and their Column values between a monday.com board and Postgres so ops teams work in SQL while project owners stay in monday.com.
  • 02 Write closed deals or provisioning records from a CRM or ERP into monday.com Items to kick off delivery and onboarding boards.
  • 03 Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • 04 Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.

Common sync patterns

Where Monday handles support or shared inboxes

Tickets and conversations attach to the right contact and account in Apollo.io, so sales sees open issues before the next call.

Where Monday supplies contact or company data

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

Where Monday can store CRM context: fields kept current

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

What you can sync between Apollo.io and Monday

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 Monday objects How this pairing syncs
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. Boards Table-like containers that hold items; each board maps to a synced table, and its columns define the field mapping. Deals (Opportunities) is specific to Apollo.io and Boards to Monday — 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. Items Rows within a board and the primary record; synced two-way and created, updated, archived, or deleted via GraphQL mutations. Tasks and calls is specific to Apollo.io and Items to Monday — each maps to any object or custom field on the other side.
Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. Subitems Nested rows under items, stored on a separate hidden board; synced as a child table linked to the parent item. Custom fields is specific to Apollo.io and Subitems to Monday — each maps to any object or custom field on the other side.
Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Column values Typed fields (status, date, people, numbers, connect-boards); polymorphic JSON usually written together via change_multiple_column_values. Contacts is specific to Apollo.io and Column values to Monday — each maps to any object or custom field on the other side.
Accounts Company records with firmographic attributes, matched to CRM accounts during sync. Groups Named sections that group items inside a board; synced as a grouping attribute or category field on the row. Accounts is specific to Apollo.io and Groups to Monday — 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. Updates Comment and activity threads attached to items; read out into a database for reporting or written back as notes. People (database records) is specific to Apollo.io and Updates to Monday — each maps to any object or custom field on the other side.

How changes propagate between Apollo.io and Monday

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

Monday Apollo.io Sub-second propagation

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 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.
  • Monday: Complexity-budget limits: a single query caps at 5M complexity points and ~10M points/min per user token (1M on trial/free) over a sliding 60s window.
