Why teams connect Salesforce Marketing Cloud and Salesloft

Keep the people you sell to and the people you market to in one shared view: Salesloft and Salesforce Marketing Cloud sync contacts, accounts, and engagement in real time, in both directions.

Salesloft owns the customer relationship and the pipeline; Salesforce Marketing Cloud 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 Accounts, Cadences, Cadence Memberships, Emails in Salesloft with Tracking Events, Transactional Sends, Data Extensions, Contacts / Subscribers in Salesforce Marketing Cloud field by field, in real time, and in both directions. You decide which system owns which fields — Salesloft can own account and opportunity status while Salesforce Marketing Cloud owns engagement and campaign membership — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Sync people, cadence memberships, and outcomes into a warehouse so RevOps can report on sequence performance next to pipeline data.
  • 02 Auto-enroll leads into cadences when a row in an enrichment database meets a scoring condition.
  • 03 Fire Journey Builder entry events (/interaction/v1/events) from an app or database when a contact acts, so behavioral journeys trigger on live events instead of scheduled batch loads.
  • 04 Land tracking events - Sent, Open, Click, Bounce, Unsubscribe - from the SOAP tracking objects or Automation Studio Data Views into a warehouse table for per-send deliverability 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 Salesforce Marketing Cloud builds lists, segments, or ad audiences, membership tracks the fields and stage owned in Salesloft, so who receives a campaign reflects current pipeline reality instead of a stale export.

Where Salesforce Marketing Cloud generates leads: hand-off without re-keying

New leads or responders captured in Salesforce Marketing Cloud flow into Salesloft assigned and deduplicated, so nothing sits in a marketing list waiting for someone to export it.

What you can sync between Salesforce Marketing Cloud and Salesloft

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.

Salesforce Marketing Cloud objects Salesloft objects How this pairing syncs
Automations (Automation Studio) Scheduled or triggered workflows of import, query, extract, and send activities managed via /automation/v1/automations; SQL Query Activities read Data Views and write results into Data Extensions. Custom Fields Per-person and per-account fields commonly populated by enrichment syncs for personalization. Automations (Automation Studio) is specific to Salesforce Marketing Cloud and Custom Fields to Salesloft — each maps to any object or custom field on the other side.
Tracking Events Sent, Open, Click, Bounce, Unsubscribe, and NotSent events retrieved through the SOAP tracking objects (SentEvent, OpenEvent, ClickEvent, BounceEvent) or the Automation Studio Data Views (_Sent, _Open, _Click, _Bounce) - the queryable record of engagement per send. People Prospect records with contact data and CRM ID mappings, the primary sync target. Tracking Events is specific to Salesforce Marketing Cloud and People to Salesloft — each maps to any object or custom field on the other side.
Transactional Sends Triggered and transactional Email/SMS delivered through the Messaging API (/messaging/v1/email/messages/{key}); the Event Notification Service reports each message's disposition (delivered, bounced, opened, clicked). Accounts Company records mirrored from the CRM for account-based workflows. Transactional Sends is specific to Salesforce Marketing Cloud and Accounts to Salesloft — each maps to any object or custom field on the other side.
Data Extensions Custom relational tables that store subscriber, audience, and arbitrary business data; rows are read via GET /data/v1/customobjectdata or SOAP Retrieve and upserted via the synchronous rowset PUT or the async /data/v1/async/dataextensions rows endpoint. This is the primary two-way surface. Cadences Multi-step outreach sequences that people are enrolled in and reported on. Data Extensions is specific to Salesforce Marketing Cloud and Cadences to Salesloft — each maps to any object or custom field on the other side.
Contacts / Subscribers The contact model keyed by Subscriber Key, holding channel addresses and subscription status; managed through the Contacts API (/contacts/v1/contacts) and the SOAP Subscriber object, and referenced by every send and journey. Cadence Memberships Enrollment records linking a person to a cadence step and status. Contacts / Subscribers is specific to Salesforce Marketing Cloud and Cadence Memberships to Salesloft — each maps to any object or custom field on the other side.
Journeys (Journey Builder) Multi-step automated flows read and managed via /interaction/v1/interactions; contacts are injected by firing an entry event to /interaction/v1/events with an EventDefinitionKey and contact data. Emails Sent and received email activity with engagement metadata, synced out for analytics. Journeys (Journey Builder) is specific to Salesforce Marketing Cloud and Emails to Salesloft — each maps to any object or custom field on the other side.

How changes propagate between Salesforce Marketing Cloud and Salesloft

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.

Salesforce Marketing Cloud Salesloft Sub-second propagation

DetectionSalesforce Marketing Cloud notifies Stacksync of record changes through webhook events. The Event Notification Service (ENS) issues HTTPS POST callbacks for transactional Email and SMS events (sent, bounce, open, click) once a callback.

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

Salesloft Salesforce Marketing Cloud Sub-second propagation

DetectionSalesloft notifies Stacksync of record changes through webhook events. Webhook event subscriptions plus polling on updated_at timestamps.

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

Rate-limit considerations

  • Salesforce Marketing Cloud: Salesforce does not publish fixed numeric REST rate limits; requests are throttled per account and can return HTTP 429, so backoff is advised. SOAP Retrieve returns at most 2,500 records per call and pages via ContinueRequest with the prior RequestID. Bulk Data Extension writes use the async rows API to queue inserts in the background.
  • Salesloft: Subject to the platform's per-minute API rate limits.

How the Salesforce Marketing Cloud and Salesloft connectors work

Salesforce Marketing Cloud

Integration surface
Two APIs on tenant-specific endpoints: a REST API (JSON over HTTPS) for Data Extensions, Journeys, Contacts, Content Builder, and Automations, plus a legacy SOAP API (ExactTarget WSDL) for tracking events and bulk Retrieve.
Authentication
OAuth 2.0 via an Installed Package (Client ID + Client Secret). Server-to-server uses the client_credentials grant and web apps use authorization_code, both against {subdomain}.auth.marketingcloudapis.com/v2/token. The 20-minute access token response also returns the account's rest_instance_url and soap_instance_url.
Change detection
The Event Notification Service (ENS) issues HTTPS POST callbacks for transactional Email and SMS events (sent, bounce, open, click) once a callback URL and subscription are registered and verified. There is no general data-change feed, so Data Extension and Data View syncs poll by date fields.
