Why teams connect Amazon S3 and Clearbit

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

Clearbit 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 Clearbit — without exports, scripts, or schedulers.

Clearbit 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 Done by hand, files drift away from the records they belong to and copies fall out of date.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 Companies, Persons, Reveal matches, Name-to-domain lookups in Clearbit aligned with Prefixes (folders), Multipart uploads, Buckets, Objects 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 Clearbit; and records from Clearbit 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 Enrich new CRM leads with person and company attributes as they are created, keyed by email and domain.
  • 02 Append technographic fields to account records in the warehouse for ICP scoring models.
  • 03 Two-way sync Object tags with a database so retention or classification labels set in an internal app write back onto S3 objects via the tagging API without rewriting the files.
  • 04 Mirror Objects under a given Bucket and prefix into another bucket, region, or a warehouse external stage for backup or downstream processing.

Common sync patterns

One place for a customer's files

Attachments that accumulate against a record in Clearbit collect in that customer's folder in Amazon S3, so the full document history lives in one place and is reachable by anyone who needs it.

A folder per account or deal

When an account or deal is created in Clearbit, 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 Clearbit, so the customer's paperwork sits with the relationship instead of a shared drive.

What you can sync between Amazon S3 and Clearbit

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 Clearbit objects How this pairing syncs
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. Reveal matches IP-to-company resolutions used to identify anonymous website traffic. Multipart uploads is specific to Amazon S3 and Reveal matches to Clearbit — 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. Name-to-domain lookups Company name resolution used to normalize account records before enrichment. Buckets is specific to Amazon S3 and Name-to-domain lookups to Clearbit — 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. Enrichment attributes The firmographic and technographic fields appended to destination records. Objects is specific to Amazon S3 and Enrichment attributes to Clearbit — 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. Companies Firmographic profiles looked up by domain and merged into account records. Object metadata is specific to Amazon S3 and Companies to Clearbit — 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. Persons Individual profiles looked up by email and used to enrich contacts and leads. Object tags is specific to Amazon S3 and Persons to Clearbit — each maps to any object or custom field on the other side.

How changes propagate between Amazon S3 and Clearbit

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 Clearbit 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.

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

Clearbit Amazon S3 Sub-second propagation

DetectionClearbit notifies Stacksync of record changes through webhook events. On-demand lookups.

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.
  • Clearbit: Subject to plan-based API rate limits and lookup volumes.

How the Amazon S3 and Clearbit connectors work

Amazon S3

Integration surface
S3 REST API (also via AWS SDKs and the S3-compatible endpoint)

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
