Two-way sync
Changes in Azure Cosmos DB or Salesforce Marketing Cloud instantly reflect in both systems. No stale data, no manual imports.
Keep Azure Cosmos DB and Salesforce Marketing Cloud in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
Salesforce Marketing Cloud holds the people, audiences, and campaign activity that marketing runs on, but that data sits behind interfaces built for marketers, not for your internal systems. Engineers and analysts who need contacts, list membership, or engagement, for reporting, attribution, or product logic, end up writing integration code against a rate-limited API and maintaining it forever. Meanwhile the customer and usage data marketers want for targeting already lives in Azure Cosmos DB, hard to get into campaigns without manual exports.
Stacksync mirrors Journeys (Journey Builder), Content Assets (Content Builder), Automations (Automation Studio), Tracking Events from Salesforce Marketing Cloud into Partition keys, Change feed entries, Stored procedures and triggers, Databases in Azure Cosmos DB field by field, in real time, and in both directions. Marketing records become rows your code can query and join with product and customer data; audiences and attributes computed in Azure Cosmos DB, from usage, orders, or account status, sync back into Salesforce Marketing Cloud to drive campaigns and ads, with Salesforce Marketing Cloud kept authoritative for engagement. You decide which side owns which fields, and Stacksync resolves conflicts by rules you set.
Contacts, leads, audiences, and campaign metrics from Salesforce Marketing Cloud live in Azure Cosmos DB as ordinary tables or collections, joinable with the rest of your data and reachable without touching the vendor API.
Segments computed in Azure Cosmos DB from product usage, orders, or account status sync into Salesforce Marketing Cloud as lists or audiences, so campaigns and ads target the people your data says they should.
Opens, clicks, sends, RSVPs, or ad activity from Salesforce Marketing Cloud land in Azure Cosmos DB beside the matching customer record, ready for reporting and revenue attribution.
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 Cosmos DB objects | Salesforce Marketing Cloud objects | How this pairing syncs | |
|---|---|---|---|
| Containers The unit of partitioning and throughput; each container maps to a synced collection. | 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. | Containers is specific to Azure Cosmos DB and Tracking Events to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. | |
| Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed. | 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). | Items (JSON documents) is specific to Azure Cosmos DB and Transactional Sends to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. | |
| Partition keys Determine data distribution and must be included on writes for the sync to route items correctly. | 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. | Partition keys is specific to Azure Cosmos DB and Data Extensions to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. | |
| Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync. | 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. | Change feed entries is specific to Azure Cosmos DB and Contacts / Subscribers to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. | |
| Stored procedures and triggers Server-side logic scoped to a partition; relevant when writes must respect existing validation. | 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. | Stored procedures and triggers is specific to Azure Cosmos DB and Journeys (Journey Builder) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. | |
| Databases Top-level namespaces that scope containers and throughput provisioning. | 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. | Databases is specific to Azure Cosmos DB and Content Assets (Content Builder) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. |
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.
DetectionChanges in Azure Cosmos DB are captured at the source via change data capture — no polling loop against its API. Built-in change feed exposing inserts and updates in order within each partition key range.
DeliveryEach detected change is written to Salesforce Marketing Cloud through its API, with automatic retries and rate-limit backoff.
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 Cosmos DB as a row-level write, with types converted between the two schemas.

Yes. Stacksync provides a managed, real-time two-way integration between Azure Cosmos DB and Salesforce Marketing Cloud: authenticate both systems, choose the objects to sync (such as Azure Cosmos DB's Containers and Items (JSON documents)), map fields visually, and changes propagate both ways in milliseconds — no code required.
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
Common patterns for Azure Cosmos DB and Salesforce Marketing Cloud: Query Salesforce Marketing Cloud like a database; Build audiences from your own data; Engagement and results next to the customer. Contacts, leads, audiences, and campaign metrics from Salesforce Marketing Cloud live in Azure Cosmos DB as ordinary tables or collections, joinable with the rest of your data and reachable without touching the vendor API.
Azure Cosmos DB: REST API and SDKs over HTTPS (API for NoSQL, formerly the SQL API); also MongoDB, Cassandra, Gremlin, and Table API surfaces. Authentication: Account keys, resource tokens, or Microsoft Entra ID role-based access. Salesforce Marketing Cloud: 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. Stacksync manages authentication, retries, and rate limits on both sides.
Azure Cosmos DB: The same account can be exposed through multiple wire-compatible APIs (NoSQL, MongoDB, Cassandra, Gremlin, Table), and the API choice fixes how a connector must speak to it. Salesforce Marketing Cloud: It exposes two APIs: a REST API (JSON) for Data Extensions, Journeys, Contacts, Content Builder, and Automations, and a legacy SOAP API (ExactTarget WSDL) for tracking events and bulk Retrieve. Stacksync's field mapping accounts for these differences between Azure Cosmos DB and Salesforce Marketing Cloud without custom code.
