Why teams connect Salesforce Marketing Cloud and Scaleway Postgres

Give your team Salesforce Marketing Cloud's contacts, campaigns, and engagement in Scaleway Postgres: query them with SQL, push audiences built from your own data back to Salesforce Marketing Cloud, and skip the marketing API.

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 Scaleway Postgres, hard to get into campaigns without manual exports.

Stacksync mirrors Tracking Events, Transactional Sends, Data Extensions, Contacts / Subscribers from Salesforce Marketing Cloud into Schemas, Sequences, Columns, Tables in Scaleway Postgres 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 Scaleway Postgres, 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.

Common use cases

  • 01 Sync production tables from Scaleway Postgres into a CRM so sales and support see live product usage on customer records
  • 02 Run a two-way sync between Scaleway Postgres and SaaS tools so edits made in either system converge on the same rows
  • 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

Engagement and results next to the customer

Opens, clicks, sends, RSVPs, or ad activity from Salesforce Marketing Cloud land in Scaleway Postgres beside the matching customer record, ready for reporting and revenue attribution.

React to marketing changes as row changes

A new lead, form fill, or list change in Salesforce Marketing Cloud arrives as a row change in Scaleway Postgres, so scoring, jobs, and notifications run in the tooling your team already uses.

Keep contact attributes consistent

Lifecycle stage, subscription status, or plan maintained on either side stays current on the other, ending exports and dual data entry.

What you can sync between Salesforce Marketing Cloud and Scaleway Postgres

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 Scaleway Postgres objects How this pairing syncs
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. Schemas Namespace tables so multiple applications or environments can be synced selectively. Contacts / Subscribers is specific to Salesforce Marketing Cloud and Schemas to Scaleway Postgres — 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. Sequences Generate primary keys; sync tooling must respect them when writing rows. Journeys (Journey Builder) is specific to Salesforce Marketing Cloud and Sequences to Scaleway Postgres — each maps to any object or custom field on the other side.
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. Columns Postgres-native types, including JSONB and arrays, are mapped to fields in the paired system. Content Assets (Content Builder) is specific to Salesforce Marketing Cloud and Columns to Scaleway Postgres — each maps to any object or custom field on the other side.
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. Tables Primary sync unit; each table maps to an object or table on the other side of the sync. Automations (Automation Studio) is specific to Salesforce Marketing Cloud and Tables to Scaleway Postgres — 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. Views Read-only sources for shaping data before it leaves the database. Tracking Events is specific to Salesforce Marketing Cloud and Views to Scaleway Postgres — 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). Materialized views Precomputed result sets that can be read on a schedule for downstream syncs. Transactional Sends is specific to Salesforce Marketing Cloud and Materialized views to Scaleway Postgres — each maps to any object or custom field on the other side.

How changes propagate between Salesforce Marketing Cloud and Scaleway Postgres

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 Scaleway Postgres 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 Scaleway Postgres as a row-level write, with types converted between the two schemas.

Scaleway Postgres Salesforce Marketing Cloud Sub-second propagation

DetectionChanges in Scaleway Postgres are captured at the source via change data capture — no polling loop against its API. Log-based CDC via PostgreSQL logical replication where the managed instance permits it.

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.
  • Scaleway Postgres: Throughput is bounded by instance size and connection limits rather than API quotas.

How the Salesforce Marketing Cloud and Scaleway Postgres 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.
