Why teams connect Amazon S3 and Freshsales
Keep the paperwork with the relationship: Freshsales and Amazon S3 share every customer's records and files in real time, in both directions.
Freshsales 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 Done by hand, files drift away from the records they belong to and copies fall out of date.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 Tasks, Appointments, Notes, Sales activities in Freshsales aligned with Multipart uploads, Buckets, Objects, Object metadata 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 Freshsales; and records from Freshsales 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 deals into a data warehouse for pipeline reporting alongside product usage data.
- 02 Push product-qualified leads from the warehouse into Freshsales as contacts with lifecycle stages set.
- 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 Freshsales 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 Freshsales, 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 Freshsales 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 Freshsales
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 | Freshsales 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. | Deals Pipeline records synced to a warehouse for revenue reporting. | Multipart uploads is specific to Amazon S3 and Deals to Freshsales — 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. | Tasks Rep to-dos created from external triggers or synced for productivity reporting. | Buckets is specific to Amazon S3 and Tasks to Freshsales — 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. | Appointments Scheduled meetings readable for activity analytics. | Objects is specific to Amazon S3 and Appointments to Freshsales — 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. | Notes Free-text records attached to contacts, accounts, and deals. | Object metadata is specific to Amazon S3 and Notes to Freshsales — 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. | Sales activities Configurable activity types logged against records, useful for engagement scoring. | Object tags is specific to Amazon S3 and Sales activities to Freshsales — 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 Catalog items attached to deals for line-level revenue data. | Object versions is specific to Amazon S3 and Products to Freshsales — each maps to any object or custom field on the other side. |
How changes propagate between Amazon S3 and Freshsales
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 Freshsales 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 Freshsales 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.
- Freshsales: Subject to per-account API rate limits that vary by Freshworks plan.
