Why teams connect Folk CRM and Marketo

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

Folk 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 Notes, Reminders, People, Companies in Folk 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 — Folk 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 Sync folk people and companies with a marketing or outbound tool so outreach lists stay current.
  • 02 Push enriched contact data from a data warehouse into folk custom fields.
  • 03 Add or remove Leads on Static Lists or set Program Member status from lifecycle stage computed downstream, then run a trigger Smart Campaign against them.
  • 04 Sync Opportunities and Opportunity Roles into Marketo so revenue and pipeline data can drive account-aware nurture and reporting.

Common sync patterns

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 Folk CRM, so who receives a campaign reflects current pipeline reality instead of a stale export.

Where Marketo generates leads: hand-off without re-keying

New leads or responders captured in Marketo flow into Folk CRM assigned and deduplicated, so nothing sits in a marketing list waiting for someone to export it.

What you can sync between Folk 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.

Folk CRM objects Marketo objects How this pairing syncs
Companies Organization records linked to people and kept aligned with billing or CS systems. Companies Company records linked to Leads via a company link field; read and upserted through /rest/v1/companies.json, typically mastered in a CRM or ERP and written into Marketo for account context. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Groups Shared workspaces that organize contacts; group membership is often the field integrations act on. 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. Groups is specific to Folk CRM and Static Lists to Marketo — each maps to any object or custom field on the other side.
Custom fields Group-scoped attributes that receive enriched or computed values from external 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. Custom fields is specific to Folk CRM and Programs and Program Members to Marketo — each maps to any object or custom field on the other side.
Notes Free-text context attached to people and companies, readable for 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. Notes is specific to Folk CRM and Smart Campaigns to Marketo — each maps to any object or custom field on the other side.
Reminders Follow-up items that can be created from external triggers. 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. Reminders is specific to Folk CRM and Leads to Marketo — each maps to any object or custom field on the other side.
People Contact records; the primary entity synced with outreach and enrichment tools. Opportunities and Opportunity Roles Revenue objects synced via /rest/v1/opportunities.json and /rest/v1/opportunities/roles.json; roles associate an opportunity with a Lead, so pipeline data can drive nurture and scoring. People is specific to Folk CRM and Opportunities and Opportunity Roles to Marketo — each maps to any object or custom field on the other side.

How changes propagate between Folk 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.

Folk CRM Marketo Sub-second propagation

DetectionFolk CRM notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, with polling of list endpoints as a fallback.

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

Marketo Folk 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 Folk CRM through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Folk CRM: Subject to the platform's API rate limits.
  • 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.

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.
