Why teams connect Attio and Salesforce Marketing Cloud

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

Attio 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 Deals, Workspaces, Custom objects, People in Attio with Content Assets (Content Builder), Automations (Automation Studio), Tracking Events, Transactional Sends in Salesforce Marketing Cloud field by field, in real time, and in both directions. You decide which system owns which fields — Attio 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 Keep Attio aligned with a billing system or ERP on customer records and plan status.
  • 02 Mirror lists and list entries into a database for pipeline reporting beyond the in-app views.
  • 03 Stream Event Notification Service callbacks for transactional sends, bounces, opens, and clicks into a database in near real time alongside CRM contact records.
  • 04 Two-way sync Data Extension rows between Marketing Cloud and a Postgres database or warehouse so audience attributes and opt-out state stay aligned in both systems.

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 Attio, 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 Attio assigned and deduplicated, so nothing sits in a marketing list waiting for someone to export it.

What you can sync between Attio and Salesforce Marketing Cloud

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.

Attio objects Salesforce Marketing Cloud objects How this pairing syncs
Workspaces Synced with incremental and full sync per the Stacksync docs. 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. Workspaces is specific to Attio and Journeys (Journey Builder) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Custom objects Workspace-defined objects that behave like standard ones in the API. Content Assets (Content Builder) Emails, templates, images, and reusable content blocks stored in Content Builder and read or written via /asset/v1/content/assets, used to compose the messages a journey or send delivers. Custom objects is specific to Attio and Content Assets (Content Builder) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
People Standard person object; synced with marketing tools and warehouse person tables. 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. People is specific to Attio and Automations (Automation Studio) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Companies Standard company object; matched to billing and product accounts in two-way syncs. 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. Companies is specific to Attio and Tracking Events to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Users Synced with incremental and full sync per the Stacksync docs. 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). Users is specific to Attio and Transactional Sends to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Deals Pipeline records; read out for revenue reporting and written to from automation. 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. Deals is specific to Attio and Data Extensions to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.

How changes propagate between Attio and Salesforce Marketing Cloud

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.

Attio Salesforce Marketing Cloud Sub-second propagation

DetectionAttio notifies Stacksync of record changes through webhook events. Webhooks on record and list-entry events, with polling as a fallback.

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

Salesforce Marketing Cloud Attio 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 Attio through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Attio: Subject to the platform's published API rate limits.
  • 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.

Attio setup guide

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.
