Why teams connect Amazon S3 and Twenty CRM
Keep the paperwork with the relationship: Twenty CRM and Amazon S3 share every customer's records and files in real time, in both directions.
Twenty 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 Done by hand, files drift away from the records they belong to and copies fall out of date.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 Custom Objects, Attachments, Workspace Members, People in Twenty CRM 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 Twenty CRM; and records from Twenty 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 Run a continuous sync from a legacy CRM into Twenty during a migration so both systems stay usable through cutover.
- 02 Two-way sync of People and Companies between Twenty and a production Postgres database so engineers can query CRM data with SQL.
- 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 Twenty 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 Twenty 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 Twenty CRM, so the customer's paperwork sits with the relationship instead of a shared drive.
What you can sync between Amazon S3 and Twenty 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 | Twenty CRM objects | How this pairing syncs | |
|---|---|---|---|
| Prefixes (folders) Logical path segments in object keys used to scope a sync and to parallelize throughput, since S3 rate limits partition by prefix. | People Individual contact records with emails, phones, and company links; a core target for contact syncs. | Prefixes (folders) is specific to Amazon S3 and People to Twenty 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. | Companies Account-level records that group people and opportunities. | Multipart uploads is specific to Amazon S3 and Companies to Twenty 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. | Opportunities Deal records tracked through pipeline stages, synced for forecasting. | Buckets is specific to Amazon S3 and Opportunities to Twenty CRM — 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. | Tasks To-dos linked to people, companies, or deals. | Objects is specific to Amazon S3 and Tasks to Twenty CRM — 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-form notes attached to records, useful for mirroring activity from other tools. | Object metadata is specific to Amazon S3 and Notes to Twenty 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. | Custom Objects User-defined objects created in Twenty's data model settings, addressable through the same APIs as standard objects. | Object tags is specific to Amazon S3 and Custom Objects to Twenty CRM — each maps to any object or custom field on the other side. |
How changes propagate between Amazon S3 and Twenty 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 Twenty 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 Twenty CRM through its API, with automatic retries and rate-limit backoff.
Twenty CRM Amazon S3 Sub-second propagation
DetectionTwenty CRM notifies Stacksync of record changes through webhook events. Webhooks on record create, update, and delete events, or polling on record update timestamps.
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.
- Twenty CRM: Subject to the platform's API rate limits; self-hosted deployments control their own limits.
