Why teams connect Amazon S3 and Nutshell

Keep the paperwork with the relationship: Nutshell and Amazon S3 share every customer's records and files in real time, in both directions.

Nutshell 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 Done by hand, files drift away from the records they belong to and copies fall out of date.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 People, Companies, Activities, Tasks in Nutshell aligned with Object tags, Object versions, Prefixes (folders), Multipart uploads 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 Nutshell; and records from Nutshell 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 Push closed-won leads to accounting software to trigger invoicing automatically.
  • 02 Keep People and Companies consistent between Nutshell and email marketing or outreach tools.
  • 03 Index every new Object's key, size, LastModified, and user metadata into a Postgres catalog table so applications query S3 contents in SQL instead of paging ListObjectsV2.
  • 04 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.

Common sync patterns

CRM records archived into storage

Records from Nutshell 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.

Document status on the record

Metadata kept in Amazon S3, such as document type, review state, or whether an agreement is signed, updates a field on the matching record in Nutshell, so people working the account see where the paperwork stands without opening storage.

One place for a customer's files

Attachments that accumulate against a record in Nutshell 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.

What you can sync between Amazon S3 and Nutshell

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 Nutshell objects How this pairing syncs
Buckets Top-level, region-scoped containers that hold objects; enumerated to discover the namespaces and prefixes a sync should cover. Companies Account records that group people and leads for account-level syncs Buckets is specific to Amazon S3 and Companies to Nutshell — 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. Activities Logged calls, meetings, and emails used for engagement reporting Objects is specific to Amazon S3 and Activities to Nutshell — 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. Tasks Rep to-dos mirrored into external work-management or reporting systems Object metadata is specific to Amazon S3 and Tasks to Nutshell — 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. Notes Free-text history attached to leads and contacts, replicated for a full timeline Object tags is specific to Amazon S3 and Notes to Nutshell — 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. Products Line items attached to leads, used to sync sold products into billing Object versions is specific to Amazon S3 and Products to Nutshell — 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. Tags Segmentation labels mapped to lists or filters in downstream tools Prefixes (folders) is specific to Amazon S3 and Tags to Nutshell — each maps to any object or custom field on the other side.

How changes propagate between Amazon S3 and Nutshell

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 Nutshell 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.

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

Nutshell Amazon S3 Sub-second propagation

DetectionNutshell notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, with polling as fallback.

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.
  • Nutshell: Subject to the platform's API rate limits.
