Why teams connect Marketo and Vtiger CRM

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

Vtiger 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 Organizations, Leads, Opportunities, Cases in Vtiger CRM with Activities and Lead Changes, Static Lists, Programs and Program Members, Smart Campaigns in Marketo field by field, in real time, and in both directions. You decide which system owns which fields — Vtiger 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 Two-way contact and organization sync between Vtiger and a billing or ERP system.
  • 02 Sync Cases to an external help desk or engineering tracker so support and product teams work from the same tickets.
  • 03 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.
  • 04 Extract Marketo Activities (opens, clicks, form fills, Data Value Changes) through Bulk Activity Extract or Get Lead Activities into a warehouse for lead scoring and multi-touch attribution.

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

What you can sync between Marketo and Vtiger CRM

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.

Marketo objects Vtiger CRM objects How this pairing syncs
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. Leads Unqualified prospects that convert into contacts, organizations, and opportunities. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
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. Sales Orders Order records between quote and invoice, synced to fulfillment systems. Programs and Program Members is specific to Marketo and Sales Orders to Vtiger CRM — each maps to any object or custom field on the other side.
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. Invoices Billing documents pushed into accounting software. Smart Campaigns is specific to Marketo and Invoices to Vtiger CRM — each maps to any object or custom field on the other side.
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. Campaigns Marketing campaign records tied to leads and contacts. Companies is specific to Marketo and Campaigns to Vtiger CRM — each maps to any object or custom field on the other side.
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. Contacts Person records linked to organizations; a core target for two-way contact syncs. Opportunities and Opportunity Roles is specific to Marketo and Contacts to Vtiger CRM — each maps to any object or custom field on the other side.
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. Organizations Company and account records. Custom Objects is specific to Marketo and Organizations to Vtiger CRM — each maps to any object or custom field on the other side.

How changes propagate between Marketo and Vtiger CRM

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.

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

Vtiger CRM Marketo Sub-second propagation

DetectionVtiger CRM notifies Stacksync of record changes through webhook events. Polling on record modified timestamps.

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

Rate-limit considerations

  • 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.
  • Vtiger CRM: Subject to the platform's API rate limits, which vary by edition.

How the Marketo and Vtiger CRM connectors work

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.
