Why teams connect Amazon S3 and ConnectWise

Land the records and documents that build up in ConnectWise into Amazon S3 as they are created, and surface Amazon S3's file details on the ConnectWise records that point to them, without an export job to maintain.

ConnectWise and Amazon S3 hold different kinds of data. ConnectWise 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 ConnectWise produces has to be kept somewhere durable, and many of the files Amazon S3 stores are the very documents ConnectWise's records point to.

Stacksync syncs Activities, Companies, Contacts, Service Tickets in ConnectWise with Objects, Object metadata, Object tags, Object versions in Amazon S3 in real time. Records and attachments created in ConnectWise 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 ConnectWise, 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.

Common use cases

  • 01 Push closed-won opportunities from the CRM into ConnectWise to kick off agreements and onboarding projects.
  • 02 Reconcile ConnectWise invoices and agreements against the accounting system to catch billing gaps.
  • 03 Reconcile Object versions and delete markers into an audit table so teams track when files under a compliance prefix were added, replaced, or removed.
  • 04 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.

Common sync patterns

Feed a data lake or downstream pipeline

Structured records from ConnectWise land in Amazon S3 as objects a data lake, search index, or processing pipeline can read, without a custom extract to build and babysit.

Archive what ConnectWise produces into Amazon S3

Records and events from ConnectWise — tickets, messages, orders, or issues — are written into Amazon S3 as objects or files as they change, giving you a durable, addressable copy for retention and audit.

Where ConnectWise generates attachments: keep the files in Amazon S3

Documents attached to records in ConnectWise land in the storage system automatically, with the source record holding a link back, so files live in one governed place instead of inside the tool.

What you can sync between Amazon S3 and ConnectWise

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 ConnectWise 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. Contacts People attached to companies, commonly synced against CRM contact records. Buckets is specific to Amazon S3 and Contacts to ConnectWise — 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. Service Tickets Support and service desk tickets, including status, board, and priority fields. Objects is specific to Amazon S3 and Service Tickets to ConnectWise — 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. Opportunities Sales pipeline records synced to CRMs for forecasting and handoff. Object metadata is specific to Amazon S3 and Opportunities to ConnectWise — 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. Agreements Recurring contracts and managed-service agreements used for billing reconciliation. Object tags is specific to Amazon S3 and Agreements to ConnectWise — 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. Projects Project and phase records synced for delivery tracking outside the PSA. Object versions is specific to Amazon S3 and Projects to ConnectWise — 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. Time Entries Logged technician time, often exported for payroll and invoicing checks. Prefixes (folders) is specific to Amazon S3 and Time Entries to ConnectWise — each maps to any object or custom field on the other side.

How changes propagate between Amazon S3 and ConnectWise

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 ConnectWise 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 ConnectWise through its API, with automatic retries and rate-limit backoff.

ConnectWise Amazon S3 Sub-second propagation

DetectionConnectWise notifies Stacksync of record changes through webhook events. Callbacks (webhooks) on record changes, supplemented by polling on last-updated fields.

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.
  • ConnectWise: Subject to the platform's API rate limits per company and integration.
