Why teams connect Azure Synapse Analytics and Salesforce Marketing Cloud

Put modeled data to work and measure what it drives: Azure Synapse Analytics and Salesforce Marketing Cloud keep contacts, audiences, and campaign results in step in real time, in both directions.

Azure Synapse Analytics is where your team models customers, product usage, and revenue into trusted tables; Salesforce Marketing Cloud runs the campaigns, audiences, and messages that reach those people. The two overlap wherever the same person, account, or segment matters to both, and when the bridge between them is a nightly export or a hand-built list, marketing targets stale data while analytics never sees what the campaign returned.

Stacksync syncs Views, Schemas, Materialized views, SQL pools in Azure Synapse Analytics 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 — a computed score or segment can flow out to Salesforce Marketing Cloud while sends, opens, and conversions flow back to Azure Synapse Analytics — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Load CRM and ERP records into Synapse dedicated SQL pool tables for enterprise reporting.
  • 02 Publish warehouse aggregates (account health scores, LTV) from Synapse back into operational tools like a CRM.
  • 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

Enrich records with warehouse context

Product-usage counts, plan tier, region, or account owner computed in Azure Synapse Analytics appear on the matching record in Salesforce Marketing Cloud, so targeting, routing, and personalization use up-to-date context.

Activate a modeled audience

A segment or score built in Azure Synapse Analytics — high-intent accounts, churn risk, a lifetime-value tier — lands as an audience or contact field in Salesforce Marketing Cloud, so campaigns target the people your data actually points to instead of a static export.

Keep the contact and audience list current

New and updated contacts, leads, or audience members flow between Azure Synapse Analytics and Salesforce Marketing Cloud, so the marketing audience reflects the people in your warehouse and corrections propagate instead of the two sides drifting apart.

What you can sync between Azure Synapse Analytics 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.

Azure Synapse Analytics objects Salesforce Marketing Cloud objects How this pairing syncs
External tables Tables over files in the data lake, queried through serverless SQL and often read-only in 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. External tables is specific to Azure Synapse Analytics and Tracking Events to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Views Curated projections used when downstream tools should not read base tables directly. 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). Views is specific to Azure Synapse Analytics and Transactional Sends to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Schemas Namespaces that separate staging, integration, and presentation layers. 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. Schemas is specific to Azure Synapse Analytics and Data Extensions to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Materialized views Precomputed aggregates that speed reads of frequently synced result sets. 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. Materialized views is specific to Azure Synapse Analytics and Contacts / Subscribers to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
SQL pools Dedicated or serverless compute contexts that determine how and where queries run. 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. SQL pools is specific to Azure Synapse Analytics and Journeys (Journey Builder) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Tables (dedicated SQL pool) Distributed warehouse tables that serve as sync destinations for analytics workloads. 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. Tables (dedicated SQL pool) is specific to Azure Synapse Analytics and Content Assets (Content Builder) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.

How changes propagate between Azure Synapse Analytics 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.

Azure Synapse Analytics Salesforce Marketing Cloud Interval-based propagation

DetectionStacksync polls Azure Synapse Analytics for changes on an incremental schedule, reading only records changed since the previous pass. Polling on watermark columns.

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

Salesforce Marketing Cloud Azure Synapse Analytics 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 applied to Azure Synapse Analytics as a row-level write, with types converted between the two schemas.

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.

How the Azure Synapse Analytics and Salesforce Marketing Cloud connectors work

Azure Synapse Analytics

Integration surface
SQL wire protocol (TDS) with T-SQL for SQL pools; additional Spark and pipeline surfaces exist but syncs use the SQL endpoint
Authentication
SQL authentication or Microsoft Entra ID

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.
