Why teams connect Amazon S3 and Folk CRM
Keep the paperwork with the relationship: Folk CRM and Amazon S3 share every customer's records and files in real time, in both directions.
Folk CRM 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 Done by hand, files drift away from the records they belong to and copies fall out of date.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, Groups, Custom fields in Folk CRM aligned with Objects, Object metadata, Object tags, Object versions 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 Folk CRM; and records from Folk CRM 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 Keep folk and a billing or customer success tool aligned on company records as deals close.
- 02 Sync folk people and companies with a marketing or outbound tool so outreach lists stay current.
- 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
One place for a customer's files
Attachments that accumulate against a record in Folk CRM 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 Folk CRM, 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 Folk CRM, so the customer's paperwork sits with the relationship instead of a shared drive.
What you can sync between Amazon S3 and Folk CRM
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 | Folk CRM 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. | Companies Organization records linked to people and kept aligned with billing or CS systems. | Object metadata is specific to Amazon S3 and Companies to Folk CRM — 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. | Groups Shared workspaces that organize contacts; group membership is often the field integrations act on. | Object tags is specific to Amazon S3 and Groups to Folk CRM — 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. | Custom fields Group-scoped attributes that receive enriched or computed values from external systems. | Object versions is specific to Amazon S3 and Custom fields to Folk CRM — 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. | Notes Free-text context attached to people and companies, readable for reporting. | Prefixes (folders) is specific to Amazon S3 and Notes to Folk CRM — 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. | Reminders Follow-up items that can be created from external triggers. | Multipart uploads is specific to Amazon S3 and Reminders to Folk CRM — 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. | People Contact records; the primary entity synced with outreach and enrichment tools. | Buckets is specific to Amazon S3 and People to Folk CRM — each maps to any object or custom field on the other side. |
How changes propagate between Amazon S3 and Folk CRM
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 Folk CRM 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 Folk CRM through its API, with automatic retries and rate-limit backoff.
Folk CRM Amazon S3 Sub-second propagation
DetectionFolk CRM notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, with polling of list endpoints as a 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.
- Folk CRM: Subject to the platform's API rate limits.

FAQ
Amazon S3 and Folk CRM integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Amazon S3 and Folk CRM: authenticate both systems, choose the objects to sync (such as Amazon S3's Object metadata and Object tags), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Amazon S3: 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. Folk CRM: REST API. Authentication: API key (Bearer token). Stacksync manages authentication, retries, and rate limits on both sides.
-
Folk CRM: Folk's model centers on people and companies organized into shared groups rather than pipeline-first objects, so group membership carries much of the workflow state. Amazon S3: S3 provides strong read-after-write consistency for all operations, but it has no built-in change feed — near-real-time detection depends on S3 Event Notifications or EventBridge being configured on the bucket. Stacksync's field mapping accounts for these differences between Amazon S3 and Folk CRM without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Amazon S3 and Folk CRM records are not retained after a sync operation.
