Why teams connect Amazon S3 and ZoomInfo

Flow ZoomInfo data into Amazon S3 in real time — no exports, no schedulers, no custom scripts.

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

ZoomInfo holds the customer relationship as structured records; Amazon S3 holds the files that belong to those relationships, from contracts and proposals to signed agreements and statements of work. The two are linked in practice and disconnected in software: someone downloads a document, renames it, and uploads it to the right folder, or exports records out to storage for retention. Done by hand, files drift away from the records they belong to and copies fall out of date.

Stacksync keeps Technographics, Company Hierarchies, Company Profiles, Contact Profiles in ZoomInfo aligned with Object metadata, Object tags, Object versions, Prefixes (folders) in Amazon S3, in real time. A new account or deal can open its own folder in Amazon S3; a document filed in Amazon S3 can surface as a link and metadata on the matching record in ZoomInfo; and records from ZoomInfo can be written into Amazon S3 as files or objects for backup, archival, and compliance. You choose which side owns what, and Stacksync keeps the two consistent as either one changes.

Common use cases

  • 01 Sync intent signals into the CRM or warehouse to trigger outbound plays on in-market accounts.
  • 02 Fill gaps in new lead records (email, phone, company size) as they enter the CRM.
  • 03 Trigger a database or ERP record update the moment an S3 Event Notification fires an object-created event, for example when a partner drops an EDI or invoice file into an inbound prefix.
  • 04 Reconcile Object versions and delete markers into an audit table so teams track when files under a compliance prefix were added, replaced, or removed.

Common sync patterns

A folder per account or deal

When an account or deal is created in ZoomInfo, a matching folder or container opens in Amazon S3, named and organized the same way, so files have a home the moment they are needed.

Documents linked back to the record

A contract, proposal, or signed agreement filed in Amazon S3 surfaces as a link on the matching record in ZoomInfo, so the customer's paperwork sits with the relationship instead of a shared drive.

CRM records archived into storage

Records from ZoomInfo are written into Amazon S3 as files or objects on the schedule you set, giving you a durable copy for backup, retention, and compliance without an export to run by hand.

What you can sync between Amazon S3 and ZoomInfo

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.

Amazon S3 objects ZoomInfo objects How this pairing syncs
Prefixes (folders) Logical path segments in object keys used to scope a sync and to parallelize throughput, since S3 rate limits partition by prefix. Scoops Event-driven signals such as leadership changes, funding rounds, and new projects. Prefixes (folders) is specific to Amazon S3 and Scoops to ZoomInfo — each maps to any object or custom field on the other side.
Multipart uploads In-progress large-object uploads assembled from parts; objects above ~100 MB (required above 5 GB) are written this way, and incomplete uploads persist until completed or aborted. Technographics Technology install data per company, used for segmentation and territory planning. Multipart uploads is specific to Amazon S3 and Technographics to ZoomInfo — each maps to any object or custom field on the other side.
Buckets Top-level, region-scoped containers that hold objects; enumerated to discover the namespaces and prefixes a sync should cover. Company Hierarchies Parent and subsidiary linkage used to align CRM account hierarchies. Buckets is specific to Amazon S3 and Company Hierarchies to ZoomInfo — each maps to any object or custom field on the other side.
Objects Files stored under a key; content is read with GET and written with PUT, and each object's key/size/ETag/LastModified is the unit indexed into a database. Company Profiles Firmographic records covering industry, size, revenue, and location, matched against CRM accounts. Objects is specific to Amazon S3 and Company Profiles to ZoomInfo — each maps to any object or custom field on the other side.
Object metadata System metadata (Content-Type, size, ETag, LastModified) plus user-defined x-amz-meta-* headers; user metadata is fixed at write time and only changeable by rewriting the object. Contact Profiles Person records with title, email, phone, and company linkage, used to enrich leads and contacts. Object metadata is specific to Amazon S3 and Contact Profiles to ZoomInfo — each maps to any object or custom field on the other side.
Object tags Up to 10 key-value tags per object, mutable in place via the tagging API independent of content, so classification and retention labels sync two-way without rewriting files. Intent Signals Company-level topic scores indicating in-market buying behavior. Object tags is specific to Amazon S3 and Intent Signals to ZoomInfo — each maps to any object or custom field on the other side.

How changes propagate between Amazon S3 and ZoomInfo

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.

Amazon S3 ZoomInfo Sub-second propagation

DetectionAmazon S3 notifies Stacksync of record changes through webhook events. S3 Event Notifications push object-created, object-removed, and object-tagging events to SNS, SQS, Lambda, or EventBridge.

DeliveryZoomInfo does not accept inbound record writes, so this direction carries requests rather than records: ZoomInfo's output flows back as field updates on the originating Amazon S3 records.

ZoomInfo Amazon S3 Interval-based propagation

DetectionStacksync polls ZoomInfo for changes on an incremental schedule, reading only records changed since the previous pass. Scheduled re-enrichment and polling.

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

Rate-limit considerations

  • Amazon S3: S3 sustains at least 3,500 PUT/COPY/POST/DELETE and 5,500 GET/HEAD requests per second per partitioned prefix and scales higher automatically; bursts can return HTTP 503 SlowDown while it repartitions.
  • ZoomInfo: Usage is metered by credits and contract-based limits rather than a single public rate limit.

How the Amazon S3 and ZoomInfo connectors work

Amazon S3

Integration surface
S3 REST API (also via AWS SDKs and the S3-compatible endpoint)
Authentication
AWS IAM credentials — an access key ID and secret access key signed with AWS Signature Version 4; supports temporary STS credentials and cross-account IAM roles
Change detection
S3 Event Notifications push object-created, object-removed, and object-tagging events to SNS, SQS, Lambda, or EventBridge; there is no modified-since query, so polling relies on each object's LastModified from ListObjectsV2

S3 sustains at least 3,500 PUT/COPY/POST/DELETE and 5,500 GET/HEAD requests per second per partitioned prefix and scales higher automatically; bursts can return HTTP 503 SlowDown while it repartitions.

ZoomInfo

Integration surface
REST API organized around search and enrich endpoints
