Why teams connect AWS S3 and DealCloud

Sync DealCloud into AWS S3 continuously and push warehouse results back onto CRM records, one two-way connection instead of two pipelines.

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. Activity, Task, User, Deal from DealCloud land in AWS S3 as live tables, updated within seconds, and columns computed in AWS S3 write back to fields in DealCloud. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • 01 Keep DealCloud contacts and relationships in sync with an enrichment or email platform to maintain accurate firm-wide relationship intelligence.
  • 02 Mirror DealCloud activities and tasks into an operational database to power internal dashboards without hitting the API on every read.
  • 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

Cleanup that sticks

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

CRM analytics on live data

Accounts, contacts, and activity from DealCloud are queryable in AWS S3 moments after they change, so dashboards stop lagging the reality they describe.

Scores and segments back on the record

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

What you can sync between AWS S3 and DealCloud

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 DealCloud objects How this pairing syncs
Event Notifications Notifications on object creation or deletion that trigger incremental processing. User Synced with incremental and full sync. Event Notifications is specific to AWS S3 and User to DealCloud — each maps to any object or custom field on the other side.
Access Points Scoped network endpoints used to grant a sync narrow access to a bucket. Deal Synced with incremental and full sync. Access Points is specific to AWS S3 and Deal to DealCloud — each maps to any object or custom field on the other side.
Multipart Uploads The mechanism used to write large export files reliably. Company Synced with incremental and full sync. Multipart Uploads is specific to AWS S3 and Company to DealCloud — 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. Contact Synced with incremental and full sync. Buckets is specific to AWS S3 and Contact to DealCloud — 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. Fund Synced with incremental and full sync. Objects is specific to AWS S3 and Fund to DealCloud — 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. Investment Synced with incremental and full sync. Prefixes is specific to AWS S3 and Investment to DealCloud — each maps to any object or custom field on the other side.

How changes propagate between AWS S3 and DealCloud

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 DealCloud 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 DealCloud through its API, with automatic retries and rate-limit backoff.

DealCloud AWS S3 Interval-based propagation

DetectionStacksync polls DealCloud for changes on an incremental schedule, reading only records changed since the previous pass. Incremental via each entry's last-modified timestamp.

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.
  • DealCloud: API request limits apply per firm tenant; Stacksync manages throttling and retries automatically.

How the AWS S3 and DealCloud 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

Rate limits
Request throughput scales per prefix; sustained high-volume workloads should spread keys across prefixes

DealCloud

Integration surface
REST API (DealCloud Data API v2)
Authentication
OAuth 2.0 client-credentials; a DealCloud administrator generates a client ID and secret in the DealCloud admin API settings and grants Stacksync the required scopes
Change detection
Incremental via each entry's last-modified timestamp; DealCloud has no universal native change-data-capture, so Stacksync polls modified rows on an interval
Capabilities
read · write
Rate limits
API request limits apply per firm tenant; Stacksync manages throttling and retries automatically.
