Why teams connect AWS S3 and Demandbase

Put modeled data to work and measure what it drives: AWS S3 and Demandbase keep contacts, audiences, and campaign results in step in real time, in both directions.

AWS S3 is where your team models customers, product usage, and revenue into trusted tables; Demandbase 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 Object Versions, Event Notifications, Access Points, Multipart Uploads in AWS S3 with People (Persons), Activities, Campaigns, Account & Person Lists (Audiences) in Demandbase 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 Demandbase while sends, opens, and conversions flow back to AWS S3 — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Stage bulk loads for warehouses that ingest from object storage.
  • 02 Archive change history from ongoing syncs as timestamped files for audit and replay.
  • 03 Enrich CRM Company and Contact records with Demandbase firmographics, technographics, and verified business emails through the B2B Company and Contact Details endpoints.
  • 04 Sync Opportunities and Activities two-way so CRM deal and engagement data flows into Demandbase reporting and Demandbase-calculated insights flow back to the warehouse.

Common sync patterns

Keep the contact and audience list current

New and updated contacts, leads, or audience members flow between AWS S3 and Demandbase, so the marketing audience reflects the people in your warehouse and corrections propagate instead of the two sides drifting apart.

Suppression and consent stay aligned

Unsubscribes, bounces, and consent or opt-out flags held in either system propagate to the other, so no one is messaged after opting out and AWS S3 holds the current state for auditing.

Enrich records with warehouse context

Product-usage counts, plan tier, region, or account owner computed in AWS S3 appear on the matching record in Demandbase, so targeting, routing, and personalization use up-to-date context.

What you can sync between AWS S3 and Demandbase

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.

AWS S3 objects Demandbase objects How this pairing syncs
Access Points Scoped network endpoints used to grant a sync narrow access to a bucket. Change Subscriptions Company firmographic, company news, family-tree (ownership), and DB person employment subscriptions delivered as webhook alerts with a signing secret; the real-time change feed. Access Points is specific to AWS S3 and Change Subscriptions to Demandbase — each maps to any object or custom field on the other side.
Multipart Uploads The mechanism used to write large export files reliably. Accounts Company/account records with firmographics, intent, and Demandbase qualification and engagement scores; exported via the Data Export API and imported or updated via the Data Import API. Multipart Uploads is specific to AWS S3 and Accounts to Demandbase — each maps to any object or custom field on the other side.
Buckets Top-level containers a sync targets; region and policy are set at this level. Opportunities Opportunity records synced from the CRM into Demandbase; exported with calculated insights and imported or updated through the Data Import API. Read and write. Buckets is specific to AWS S3 and Opportunities to Demandbase — each maps to any object or custom field on the other side.
Objects The stored files (CSV, JSON, Parquet); syncs read them as datasets or write exports into them. People (Persons) Contact/person records with verified business email, title, seniority, and quality grades; fetched and matched via the B2B Contact endpoints and exported or imported. Objects is specific to AWS S3 and People (Persons) to Demandbase — each maps to any object or custom field on the other side.
Prefixes Key-name paths used to partition synced datasets, since S3 has no real directories. Activities Engagement and custom activity records (web, campaign, intent); exported via Data Export and pushed in through the Data Import API using custom activity types. Prefixes is specific to AWS S3 and Activities to Demandbase — each maps to any object or custom field on the other side.
Object Metadata System and user-defined metadata read alongside object contents. Campaigns Marketing campaign records and creative assets exported through the Data Export API; read-only reporting feed. Object Metadata is specific to AWS S3 and Campaigns to Demandbase — each maps to any object or custom field on the other side.

How changes propagate between AWS S3 and Demandbase

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.

AWS S3 Demandbase Sub-second propagation

DetectionAWS S3 notifies Stacksync of record changes through webhook events. S3 Event Notifications on object create/delete delivered to SQS, SNS, Lambda, or EventBridge.

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

Demandbase AWS S3 Sub-second propagation

DetectionDemandbase notifies Stacksync of record changes through webhook events. Subscription API webhooks - company firmographic, company news, family-tree (ownership), and person employment-change alerts to a configurable URL.

DeliveryEach detected change is written to AWS S3 through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • AWS S3: Request throughput scales per prefix; sustained high-volume workloads should spread keys across prefixes.
  • Demandbase: Credit-based per API call; bulk jobs accept up to 10,000 records per submission, CSV uploads up to 5GB, and result URLs stay valid 24 hours; subscription alerts page up to 5,000 entities and list endpoints up to 100 per page.

How the AWS S3 and Demandbase connectors work

AWS S3

Integration surface
REST API (the S3 API), accessed directly or through AWS SDKs
Authentication
AWS IAM credentials with SigV4 signing; commonly a role scoped to specific buckets and prefixes
Change detection
S3 Event Notifications on object create/delete delivered to SQS, SNS, Lambda, or EventBridge; list-based polling as a fallback
Capabilities
read · write · webhooks
Rate limits
Request throughput scales per prefix; sustained high-volume workloads should spread keys across prefixes

Demandbase

Integration surface
REST APIs (Demandbase One) - a B2B API (company/contact search, details, and match with async bulk enrichment jobs), a read-only Data Export API and a write-capable Data Import API (both async bulk jobs), and a Subscription API for webhook change alerts.
Authentication
JWT bearer tokens minted from Demandbase One API Key Sets at the platform level; each credential set expires after 8 hours and is rotated. Legacy single-user API tokens are deprecated.
Change detection
Subscription API webhooks - company firmographic, company news, family-tree (ownership), and person employment-change alerts to a configurable URL secured with a signing secret; bulk reads run as async export jobs (submit, poll, download). No log-based CDC.
