Why teams connect Amazon DynamoDB and Cin7

Give your engineers Cin7's data in Amazon DynamoDB: read it with normal queries, write back through the sync, and skip the ERP API entirely.

ERP data sits behind interfaces built for the ERP's own modules, not for your internal systems. Teams that need those records, for reporting services, internal tools, or automations, end up writing integration code against a strict API and maintaining it through every upgrade.

Stacksync mirrors Contacts, Branches / locations, Stock adjustments and transfers, Credit notes / returns from Cin7 into Amazon DynamoDB and keeps both sides consistent in real time. Whatever Cin7 is the system of record for, whether financials, operations, people, or procurement, those records become rows your code can query, and changes written in Amazon DynamoDB sync back into Cin7 with its validations respected.

Common use cases

  • 01 Backfill or migrate records into DynamoDB from another database using BatchWriteItem, then keep the two stores in continuous sync.
  • 02 Mirror a high-write DynamoDB table into a relational database so teams can join NoSQL application data against relational tables for reporting.
  • 03 Keep customer records aligned between Cin7 and the CRM to remove duplicate account entry.
  • 04 Write purchase orders created in a planning tool back into Cin7 for receiving.

Common sync patterns

Controlled write-back

Choose exactly which tables and fields may flow from Amazon DynamoDB back into Cin7, keeping the ERP authoritative.

Read ERP records with a query

Records from Cin7 live in Amazon DynamoDB as ordinary tables or collections, joinable with the rest of your data.

Internal tools and automations without API code

Scripts and services read and write the synced tables; Stacksync handles the Cin7 interface, limits, and retries.

What you can sync between Amazon DynamoDB and Cin7

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 DynamoDB objects Cin7 objects How this pairing syncs
DynamoDB Streams Ordered item-level change records (INSERT, MODIFY, REMOVE) with old/new image views and 24-hour retention; the native change-data-capture source Stacksync reads for near-real-time sync. Purchase orders Supplier orders synced with procurement and accounting workflows. DynamoDB Streams is specific to Amazon DynamoDB and Purchase orders to Cin7 — each maps to any object or custom field on the other side.
Global Tables Multi-region, active-active replicas of a table kept in sync by DynamoDB; each region is read and written locally with last-writer-wins conflict resolution. Contacts Customers and suppliers, matched to CRM records to keep account data consistent. Global Tables is specific to Amazon DynamoDB and Contacts to Cin7 — each maps to any object or custom field on the other side.
Time to Live (TTL) Per-item expiry timestamps; DynamoDB deletes expired items in the background and emits a Streams REMOVE record for each deletion. Branches / locations Warehouse entities that scope every stock movement and order allocation. Time to Live (TTL) is specific to Amazon DynamoDB and Branches / locations to Cin7 — each maps to any object or custom field on the other side.
Tables Top-level containers, each with a partition key and optional sort key; Stacksync syncs a table as a stream of items with full read and write via PutItem, UpdateItem, and DeleteItem. Stock adjustments and transfers Inventory movements read for audit and reconciliation reporting. Tables is specific to Amazon DynamoDB and Stock adjustments and transfers to Cin7 — each maps to any object or custom field on the other side.
Items Individual schemaless records (attributes up to 400 KB each); read with GetItem, Query, and Scan and written with PutItem or BatchWriteItem, so write is supported here. Credit notes / returns Return documents synced so finance and support see the same refund state. Items is specific to Amazon DynamoDB and Credit notes / returns to Cin7 — each maps to any object or custom field on the other side.
Global secondary indexes (GSIs) Alternate key projections that let you Query by non-key attributes without a full table Scan; read-only views maintained automatically by DynamoDB. Products SKU records with options and pricing, synced with storefront and marketplace catalogs. Global secondary indexes (GSIs) is specific to Amazon DynamoDB and Products to Cin7 — each maps to any object or custom field on the other side.

How changes propagate between Amazon DynamoDB and Cin7

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 DynamoDB Cin7 Sub-second propagation

DetectionChanges in Amazon DynamoDB are captured at the source via change data capture — no polling loop against its API. DynamoDB Streams emit ordered item-level change records (INSERT, MODIFY, REMOVE) with KEYS_ONLY, NEW_IMAGE, OLD_IMAGE, or NEW_AND_OLD_IMAGES views.

DeliveryEach detected change is written to Cin7 through its API, with automatic retries and rate-limit backoff.

Cin7 Amazon DynamoDB Sub-second propagation

DetectionCin7 notifies Stacksync of record changes through webhook events. Polling on modified-date filters.

DeliveryEach detected change is applied to Amazon DynamoDB as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Amazon DynamoDB: Throughput is metered in read/write capacity units (provisioned or on-demand): 1 WCU = one 1 KB write per second, 1 RCU = one strongly-consistent 4 KB read per second. Exceeding capacity or the ~3,000 RCU / 1,000 WCU per-partition ceiling returns ProvisionedThroughputExceededException with throttling.
  • Cin7: Subject to per-account API rate limits that differ between Cin7 Omni and Cin7 Core.

How the Amazon DynamoDB and Cin7 connectors work

Amazon DynamoDB

Integration surface
AWS SDK / low-level HTTPS JSON API at dynamodb.<region>.amazonaws.com (PutItem, GetItem, UpdateItem, DeleteItem, Query, Scan, BatchWriteItem, TransactWriteItems), plus PartiQL (ExecuteStatement) for SQL-style access and DynamoDB Streams for change capture.
Authentication
AWS Signature Version 4 (SigV4) signed requests using an IAM access key ID and secret key, or temporary STS credentials from an assumed IAM role; IAM policies scope access down to table and item level.
Change detection
DynamoDB Streams emit ordered item-level change records (INSERT, MODIFY, REMOVE) with KEYS_ONLY, NEW_IMAGE, OLD_IMAGE, or NEW_AND_OLD_IMAGES views and 24-hour retention, read via shard iterators (or Kinesis Data Streams for longer retention). No native HTTP webhooks.
