Why teams connect Freshworks CRM and Marketo

Keep the people you sell to and the people you market to in one shared view: Freshworks CRM and Marketo sync contacts, accounts, and engagement in real time, in both directions.

Freshworks CRM owns the customer relationship and the pipeline; Marketo runs the campaigns, audiences, and outreach that fill it. The two overlap on the same people and companies — a lead in one system is a subscriber, a segment member, an event registrant, or an ad audience in the other. When that overlap is bridged by CSV exports or a nightly job, sales works from lists that no longer match reality and marketing keeps targeting people whose status has already moved on.

Stacksync syncs Deals, Tasks, Appointments, Sales activities in Freshworks CRM with Leads, Companies, Opportunities and Opportunity Roles, Custom Objects in Marketo field by field, in real time, and in both directions. You decide which system owns which fields — Freshworks CRM can own account and opportunity status while Marketo owns engagement and campaign membership — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Mirror deal and activity data into a Postgres database that internal tools query directly.
  • 02 Sync unified contact records, covering sales and marketing attributes, into a warehouse for full-funnel reporting.
  • 03 Sync Opportunities and Opportunity Roles into Marketo so revenue and pipeline data can drive account-aware nurture and reporting.
  • 04 Two-way sync Marketo Leads with a Postgres or warehouse table, matched on email, so RevOps queries and updates marketing profiles in SQL while marketers keep working in Marketo.

Common sync patterns

Where Marketo captures engagement: activity lands on the record

Opens, clicks, form fills, event attendance, or ad responses recorded in Marketo post back to the contact or account in Freshworks CRM, so reps see interest before they reach out.

Lead and lifecycle status agree

Status, stage, or score set in one system updates the matching record in the other, so a lead marketing is still nurturing is not worked as sales-ready, and a closed account stops receiving prospecting.

Segments and audiences follow the CRM

Where Marketo builds lists, segments, or ad audiences, membership tracks the fields and stage owned in Freshworks CRM, so who receives a campaign reflects current pipeline reality instead of a stale export.

What you can sync between Freshworks CRM and Marketo

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.

Freshworks CRM objects Marketo objects How this pairing syncs
Lists Contact list membership synced against segments computed in a warehouse. Custom Objects Auxiliary data tables described via /rest/v1/customobjects.json and read/written via /rest/v1/customobjects/{apiName}.json, linked to Leads by a dedupe/link field so campaigns branch on records like purchases or subscriptions. Lists is specific to Freshworks CRM and Custom Objects to Marketo — each maps to any object or custom field on the other side.
Notes Context records attached to contacts, accounts, and deals. Activities and Lead Changes Engagement feed (opens, clicks, form fills, Data Value Changes) read via GET /rest/v1/activities.json using a paging token from /rest/v1/activities/pagingtoken.json (sinceDatetime), plus Get Lead Changes and Get Deleted Leads; read-only, also available via async Bulk Activity Extract. Notes is specific to Freshworks CRM and Activities and Lead Changes to Marketo — each maps to any object or custom field on the other side.
Contacts Unified sales-and-marketing person records; the core entity for bidirectional syncs. Static Lists Named static lists; read via /rest/v1/lists.json, with Leads added or removed via POST and DELETE on /rest/v1/lists/{listId}/leads.json to control campaign membership from lifecycle logic computed downstream. Contacts is specific to Freshworks CRM and Static Lists to Marketo — each maps to any object or custom field on the other side.
Accounts Company records kept consistent with ERP and billing systems. Programs and Program Members Marketing programs read via /rest/v1/programs.json; program membership and member status managed via /rest/v1/leads/programs/{programId}.json and the program status endpoint for acquisition and attribution reporting. Accounts is specific to Freshworks CRM and Programs and Program Members to Marketo — each maps to any object or custom field on the other side.
Deals Pipeline records synced out for forecasting and full-funnel reporting. Smart Campaigns Automation flows read via /rest/v1/campaigns.json and run against a set of Leads by requesting a trigger campaign with POST /rest/v1/campaigns/{id}/trigger.json, so downstream logic can push Leads into a Marketo flow. Deals is specific to Freshworks CRM and Smart Campaigns to Marketo — each maps to any object or custom field on the other side.
Tasks Follow-ups created from external signals such as product usage events. Leads Core person records (called Leads/People), deduped on email address by default or a configured dedupe field; read via GET /rest/v1/leads.json with a filterType, upserted via POST /rest/v1/leads.json (action createOrUpdate/createOnly/updateOnly), bulk-imported via CSV through POST /bulk/v1/leads.json, and bulk-exported via /bulk/v1/leads/export/create.json. Tasks is specific to Freshworks CRM and Leads to Marketo — each maps to any object or custom field on the other side.

How changes propagate between Freshworks CRM and Marketo

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.

Freshworks CRM Marketo Sub-second propagation

DetectionFreshworks CRM notifies Stacksync of record changes through webhook events. Polling with updated-at filters.

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

Marketo Freshworks CRM Interval-based propagation

DetectionStacksync polls Marketo for changes on an incremental schedule, reading only records changed since the previous pass. Polling: Get Lead Changes and Get Lead Activities from a paging token seeded by a sinceDatetime, plus Get Deleted Leads, or Bulk Extract filtered on.

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

Rate-limit considerations

  • Freshworks CRM: Subject to per-account API rate limits that vary by plan.
  • Marketo: Interactive calls are capped at 100 per 20 seconds (error 606) and a maximum of 10 concurrent calls (error 615) per instance, neither increasable; a default daily quota of 50,000 calls (increasable, resets midnight CST) applies. Bulk Extract shares a 500 MB/day export quota across data types with at most 2 concurrent jobs and 10 queued.

Marketo

Integration surface
Marketo REST API (JSON over HTTPS) for Leads, Companies, Opportunities, Custom Objects, Activities, Lists, Programs, and Campaigns, plus an asynchronous Bulk Import (leads) and Bulk Extract (leads/activities/program members/custom objects) API and an Asset REST API for emails, forms, and landing pages
Authentication
OAuth 2.0 client_credentials (2-legged): GET the Identity URL /oauth/token?grant_type=client_credentials with a Custom Service client_id and client_secret to receive an access token valid for 3600 seconds, then send it as Authorization: Bearer on each call. The instance base URL is https://{munchkinId}.mktorest.com; passing the token as an access_token query parameter is deprecated (removal July 31, 2026).
Change detection
Polling: Get Lead Changes and Get Lead Activities from a paging token seeded by a sinceDatetime, plus Get Deleted Leads, or Bulk Extract filtered on createdAt/updatedAt. Marketo's Webhooks are Smart Campaign flow-step outbound HTTP calls to a URL, not a general record-change subscription, so there is no push feed of arbitrary CRUD.
