Why teams connect Amazon S3 and Dynamics 365 Business Central

Move the documents and data that Dynamics 365 Business Central produces into Amazon S3 as files, and let files stored in Amazon S3 update the records they belong to in Dynamics 365 Business Central, continuously and without exports or manual filing.

Dynamics 365 Business Central runs the business on structured records: Items, Sales Orders, Sales Invoices, Purchase Orders. Amazon S3 holds files and the metadata that describes them: Buckets, Objects, Object metadata, Object tags. The two do not share a customer table or an order ledger. What they share is documents. Nearly every record Dynamics 365 Business Central touches produces a file that belongs in storage, whether an invoice, a purchase order, a statement, or a shipping doc, and many files that land in Amazon S3, from signed contracts to vendor bills to receipts, describe a transaction Dynamics 365 Business Central needs to record. Left unconnected, that link is maintained by hand: someone exports a PDF and drags it into a folder, or downloads a file and keys its details into a record.

Stacksync keeps Items, Sales Orders, Sales Invoices, Purchase Orders in Dynamics 365 Business Central and Buckets, Objects, Object metadata, Object tags in Amazon S3 in sync, bi-directionally and in real time. A document and its details, the customer, the type, the date, an amount, an order or invoice number, are mapped field by field, so a file arrives in Amazon S3 already labeled and filed, and metadata captured against a stored file can create or update the matching record in Dynamics 365 Business Central. Changes on either side show up within seconds, with conflict resolution in place of nightly exports and manual filing.

The result is that a transaction and the document that backs it stay together. Finance, operations, and audit teams find the file behind a record without digging through folders, and the record in Dynamics 365 Business Central and the file in Amazon S3 never describe two different versions of the same document.

Common use cases

  • 01 Create sales orders in Business Central automatically from e-commerce or CRM order records, and sync fulfillment status back.
  • 02 Mirror items and inventory levels into external channels so stock data stays current outside the ERP.
  • 03 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.
  • 04 Reconcile Object versions and delete markers into an audit table so teams track when files under a compliance prefix were added, replaced, or removed.

Common sync patterns

Where Amazon S3 captures inbound files: details reach the record

A contract, vendor bill, or receipt added to Amazon S3 with its details can create or update the matching record in Dynamics 365 Business Central, so a document captured outside the finance system still reaches the books.

An archive that stays current

As records change in Dynamics 365 Business Central, the corresponding files and metadata in Amazon S3 are kept in step, so a stored document reflects the latest version rather than a stale one-time export.

Audit-ready retention

Every transaction's supporting file lives in Amazon S3 beside its metadata, giving finance and audit teams a complete, searchable trail tied back to the record in Dynamics 365 Business Central.

What you can sync between Amazon S3 and Dynamics 365 Business Central

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 Dynamics 365 Business Central 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. Purchase Orders Procurement documents exchanged with supplier-facing systems. Buckets is specific to Amazon S3 and Purchase Orders to Dynamics 365 Business Central — 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. General Ledger Entries Posted financial transactions read for reporting; posted entries are immutable. Objects is specific to Amazon S3 and General Ledger Entries to Dynamics 365 Business Central — 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. Journals Staging records for financial postings created by integrations before posting. Object metadata is specific to Amazon S3 and Journals to Dynamics 365 Business Central — 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. Dimensions Analytical tags (department, project) that syncs preserve for reporting integrity. Object tags is specific to Amazon S3 and Dimensions to Dynamics 365 Business Central — 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. Payments Customer and vendor payment records reconciled against invoices. Object versions is specific to Amazon S3 and Payments to Dynamics 365 Business Central — 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. Customers Core master data synced with CRMs so sales and finance share one customer list. Prefixes (folders) is specific to Amazon S3 and Customers to Dynamics 365 Business Central — each maps to any object or custom field on the other side.

How changes propagate between Amazon S3 and Dynamics 365 Business Central

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 Dynamics 365 Business Central 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 Dynamics 365 Business Central 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.
