Why teams connect AWS S3 and Dun And Bradstreet

Flow Dun And Bradstreet data into AWS S3 in real time — no exports, no schedulers, no custom scripts.

Dun And Bradstreet is a read-only source: Stacksync reads its data in real time and delivers it into AWS S3, so AWS S3 always reflects the current state of Dun And Bradstreet — without exports, scripts, or schedulers.

The CRM feeds the warehouse and the warehouse should feed the CRM: relationship data flows one way, and computed scores, segments, and customer context flow back. Most teams build the first half as a batch pipeline and never quite get to the second.

Stacksync does both with one connection. Criteria Search, Monitoring Notifications, Company Information (Data Block), Principals & Contacts (Data Block) from Dun And Bradstreet land in AWS S3 as live tables, updated within seconds, and columns computed in AWS S3 write back to fields in Dun And Bradstreet. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • 01 Build target-account lists with Criteria Search and land the resulting DUNS plus firmographics in a database for outbound and TAM analysis.
  • 02 Poll D&B Monitoring notifications for a registered portfolio of key accounts and suppliers and update the CRM or warehouse record whenever a firmographic or risk score changes.
  • 03 Ingest partner or vendor file drops (CSV, JSON, Parquet) from a bucket into a database or CRM as records.
  • 04 Export synced operational data to S3 as files feeding a data lake or downstream batch jobs.

Common sync patterns

Scores and segments back on the record

Lead scores, churn risk, or usage segments computed in AWS S3 appear as fields in Dun And Bradstreet, where the people working accounts actually see them.

A single customer view

Join Dun And Bradstreet's relationship data with billing, product, and support data in AWS S3 to build the customer picture the CRM alone cannot hold.

Cleanup that sticks

Deduplication and normalization done in AWS S3 can be written back, so warehouse-side cleanup actually fixes the CRM.

What you can sync between AWS S3 and Dun And Bradstreet

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 Dun And Bradstreet objects How this pairing syncs
Access Points Scoped network endpoints used to grant a sync narrow access to a bucket. Monitoring Notifications Change notices for a registered portfolio of DUNS; read-only feed pulled from the notifications endpoint (retained ~60 days) or delivered as bundled push. Access Points is specific to AWS S3 and Monitoring Notifications to Dun And Bradstreet — each maps to any object or custom field on the other side.
Multipart Uploads The mechanism used to write large export files reliably. Company Information (Data Block) Core firmographics for a D-U-N-S Number - legal name, addresses, industry codes, employees, sales, status. Retrieved read-only via the Enrich endpoint; blocks come in levels L1-L4. Multipart Uploads is specific to AWS S3 and Company Information (Data Block) to Dun And Bradstreet — 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. Principals & Contacts (Data Block) Company officers, executives, and contacts tied to a D-U-N-S Number; read-only enrichment used to populate CRM contact and account-owner fields. Buckets is specific to AWS S3 and Principals & Contacts (Data Block) to Dun And Bradstreet — 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. Company Hierarchy & Connections (Family Tree) Parent, subsidiary, branch, and global-ultimate DUNS relationships; read-only, used to build account hierarchies and corporate-family rollups. Objects is specific to AWS S3 and Company Hierarchy & Connections (Family Tree) to Dun And Bradstreet — 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. Financial Strength & Risk Insight (Data Block) D&B risk and credit signals - D&B Rating, PAYDEX, Failure Score, Delinquency Score, Viability - keyed by D-U-N-S Number; read-only. Prefixes is specific to AWS S3 and Financial Strength & Risk Insight (Data Block) to Dun And Bradstreet — each maps to any object or custom field on the other side.
Object Metadata System and user-defined metadata read alongside object contents. Identity Resolution (Match / cleanseMatch) Sends a company name and address and returns ranked candidate DUNS with confidence codes and a MatchGrade; read-only scored match, not an exact lookup. Object Metadata is specific to AWS S3 and Identity Resolution (Match / cleanseMatch) to Dun And Bradstreet — each maps to any object or custom field on the other side.

How changes propagate between AWS S3 and Dun And Bradstreet

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 Dun And Bradstreet 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.

DeliveryDun And Bradstreet does not accept inbound record writes, so this direction carries requests rather than records: Dun And Bradstreet's output flows back as field updates on the originating AWS S3 records.

Dun And Bradstreet AWS S3 Interval-based propagation

DetectionStacksync polls Dun And Bradstreet for changes on an incremental schedule, reading only records changed since the previous pass. Polling via D&B Monitoring - register a portfolio of DUNS and pull change notices from the notifications endpoint (retained ~60 days).

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.
  • Dun And Bradstreet: Per-contract transactions-per-second cap plus weekly/monthly/yearly quotas; exceeding TPS returns HTTP 429 with error 0045/0046 (0047 on spike arrest). Quotas reset on UTC boundaries.
