Two-way sync
Changes in Amazon S3 or GitHub instantly reflect in both systems. No stale data, no manual imports.
Keep Amazon S3 and GitHub in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
GitHub and Amazon S3 hold different kinds of data. GitHub 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 GitHub produces has to be kept somewhere durable, and many of the files Amazon S3 stores are the very documents GitHub's records point to.
Stacksync syncs Issues, Pull Requests, Commits, Releases in GitHub with Object tags, Object versions, Prefixes (folders), Multipart uploads in Amazon S3 in real time. Records and attachments created in GitHub 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 GitHub, 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.
A file's name, location, owner, and modified date from Amazon S3 sync onto the matching record in GitHub, so whoever is working there sees the current version without switching tools.
A continuously synced copy in Amazon S3 preserves records and documents even as they age out of GitHub or get changed inside it, so history stays intact and reachable.
Structured records from GitHub land in Amazon S3 as objects a data lake, search index, or processing pipeline can read, without a custom extract to build and babysit.
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 | GitHub objects | How this pairing syncs | |
|---|---|---|---|
| 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. | Repositories Top-level containers whose metadata and settings syncs read to scope other objects. | Object versions is specific to Amazon S3 and Repositories to GitHub — 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. | Issues Synced two-way with project trackers and support tools, including labels and assignees. | Prefixes (folders) is specific to Amazon S3 and Issues to GitHub — 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. | Pull Requests Review state, status checks, and merge status feed engineering dashboards and workflow tools. | Multipart uploads is specific to Amazon S3 and Pull Requests to GitHub — 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. | Commits Read-only history used to link code activity to tickets and releases. | Buckets is specific to Amazon S3 and Commits to GitHub — 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. | Releases Tagged versions synced into changelogs, CRMs, or customer-notification systems. | Objects is specific to Amazon S3 and Releases to GitHub — 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. | Workflow runs (Actions) CI results synced into incident and reporting systems. | Object metadata is specific to Amazon S3 and Workflow runs (Actions) to GitHub — each maps to any object or custom field on the other side. |
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.
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 GitHub through its API, with automatic retries and rate-limit backoff.

Transform legacy EDI complexity into simple database interactions between Amazon S3 and GitHub.
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate Amazon S3 and GitHub with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Amazon S3 and GitHub objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Amazon S3 and GitHub: authenticate both systems, choose the objects to sync (such as Amazon S3's Object versions and Prefixes (folders)), map fields visually, and changes propagate both ways in milliseconds — no code required.
Change detection on Amazon S3: 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. On GitHub: Webhooks with a broad event catalog covering issues, pull requests, pushes, and releases; polling for backfill. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
On the GitHub side: Issues, Pull Requests, Commits, Releases, plus custom fields where GitHub exposes them. On the Amazon S3 side: Object tags, Object versions, Prefixes (folders), Multipart uploads. Stacksync auto-detects both schemas and converts types between the two systems.
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
Common patterns for Amazon S3 and GitHub: Where Amazon S3 holds the source documents: file details on the record; A copy that outlives the tool; Feed a data lake or downstream pipeline. A file's name, location, owner, and modified date from Amazon S3 sync onto the matching record in GitHub, so whoever is working there sees the current version without switching tools.
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. GitHub: REST API and GraphQL API. Authentication: OAuth 2.0, fine-grained personal access tokens, or GitHub App installation tokens. Stacksync manages authentication, retries, and rate limits on both sides.
