Why teams connect Amazon S3 and Vtiger CRM

Keep the paperwork with the relationship: Vtiger CRM and Amazon S3 share every customer's records and files in real time, in both directions.

Vtiger 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 Done by hand, files drift away from the records they belong to and copies fall out of date.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 Opportunities, Cases, Products, Quotes in Vtiger 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 Vtiger CRM; and records from Vtiger 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 Sync Cases to an external help desk or engineering tracker so support and product teams work from the same tickets.
  • 02 Push Quotes and Invoices into accounting software to avoid re-keying billing data.
  • 03 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.
  • 04 Two-way sync Object tags with a database so retention or classification labels set in an internal app write back onto S3 objects via the tagging API without rewriting the files.

Common sync patterns

CRM records archived into storage

Records from Vtiger CRM are written into Amazon S3 as files or objects on the schedule you set, giving you a durable copy for backup, retention, and compliance without an export to run by hand.

Document status on the record

Metadata kept in Amazon S3, such as document type, review state, or whether an agreement is signed, updates a field on the matching record in Vtiger CRM, so people working the account see where the paperwork stands without opening storage.

One place for a customer's files

Attachments that accumulate against a record in Vtiger 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.

What you can sync between Amazon S3 and Vtiger 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 Vtiger CRM objects How this pairing syncs
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. Invoices Billing documents pushed into accounting software. Object tags is specific to Amazon S3 and Invoices to Vtiger 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. Campaigns Marketing campaign records tied to leads and contacts. Object versions is specific to Amazon S3 and Campaigns to Vtiger 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. Contacts Person records linked to organizations; a core target for two-way contact syncs. Prefixes (folders) is specific to Amazon S3 and Contacts to Vtiger 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. Organizations Company and account records. Multipart uploads is specific to Amazon S3 and Organizations to Vtiger 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. Leads Unqualified prospects that convert into contacts, organizations, and opportunities. Buckets is specific to Amazon S3 and Leads to Vtiger 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. Opportunities Deal records, historically the Potentials module, synced for pipeline reporting. Objects is specific to Amazon S3 and Opportunities to Vtiger CRM — each maps to any object or custom field on the other side.

How changes propagate between Amazon S3 and Vtiger 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 Vtiger 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 Vtiger CRM 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.
  • Vtiger CRM: Subject to the platform's API rate limits, which vary by edition.
