Why teams connect Amazon S3 and BetterContact

Land the records and documents that build up in BetterContact into Amazon S3 as they are created, and surface Amazon S3's file details on the BetterContact records that point to them, without an export job to maintain.

BetterContact 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 BetterContact — without exports, scripts, or schedulers.

BetterContact and Amazon S3 hold different kinds of data. BetterContact carries records and the activity around them — the tickets, messages, orders, or issues a team works through, often with documents attached. Amazon S3 holds files and the metadata that describes them. Where the two meet is narrow but real: much of what BetterContact produces has to be kept somewhere durable, and many of the files Amazon S3 stores are the very documents BetterContact's records point to.

Stacksync syncs Company, Lead Finder Search, Enrichment Request, Enriched Contact in BetterContact with Object metadata, Object tags, Object versions, Prefixes (folders) in Amazon S3 in real time. Records and attachments created in BetterContact are written into Amazon S3 as objects or files within seconds of being created. In the other direction, the metadata Amazon S3 keeps about those files — name, location, owner, modified date — flows back onto the matching record in BetterContact, so people see the current document without leaving the tool. Field-level mapping controls exactly what crosses over and in which direction, so you keep a durable copy of what matters without an extract to schedule or a nightly dump that leaves the copy a day behind.

Common use cases

  • 01 Backfill a warehouse of contacts with waterfall enrichment across 20+ data providers.
  • 02 Feed outbound sequencing tools with verified contact data before campaigns launch.
  • 03 Mirror Objects under a given Bucket and prefix into another bucket, region, or a warehouse external stage for backup or downstream processing.
  • 04 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.

Common sync patterns

Archive what BetterContact produces into Amazon S3

Records and events from BetterContact — tickets, messages, orders, or issues — are written into Amazon S3 as objects or files as they change, giving you a durable, addressable copy for retention and audit.

Where BetterContact generates attachments: keep the files in Amazon S3

Documents attached to records in BetterContact land in the storage system automatically, with the source record holding a link back, so files live in one governed place instead of inside the tool.

Where Amazon S3 holds the source documents: file details on the record

A file's name, location, owner, and modified date from Amazon S3 sync onto the matching record in BetterContact, so whoever is working there sees the current version without switching tools.

What you can sync between Amazon S3 and BetterContact

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 BetterContact objects How this pairing syncs
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. Lead Finder Search Prospect discovery by people and company filters, returning enriched lead profiles. Object metadata is specific to Amazon S3 and Lead Finder Search to BetterContact — 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. Enrichment Request Batch or single submissions of up to 100 contacts per request for waterfall enrichment. Object tags is specific to Amazon S3 and Enrichment Request to BetterContact — each maps to any object or custom field on the other side.
Object versions When bucket versioning is enabled every write creates a new version ID; prior versions and delete markers are readable for history and audit syncs. Enriched Contact Verified work emails and mobile numbers with job title, LinkedIn profile, location, and skills. Object versions is specific to Amazon S3 and Enriched Contact to BetterContact — each maps to any object or custom field on the other side.
Prefixes (folders) Logical path segments in object keys used to scope a sync and to parallelize throughput, since S3 rate limits partition by prefix. Company Company data returned with each contact: name, domain, HQ location, industry, employee count. Prefixes (folders) is specific to Amazon S3 and Company to BetterContact — each maps to any object or custom field on the other side.

How changes propagate between Amazon S3 and BetterContact

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 BetterContact 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.

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

BetterContact Amazon S3 Sub-second propagation

DetectionBetterContact notifies Stacksync of record changes through webhook events. Job-based delivery — enrichment results arrive by webhook push or polling of the results endpoint.

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.
  • BetterContact: Batches capped at 100 contacts per enrichment request.

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
