Why teams connect Customer.io and Dynamo DB
Mirror Customer.io's data into Dynamo DB so your own code can read and write it like any other table, with changes flowing both ways in seconds.
Engineers integrate with tools like Customer.io through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in Dynamo DB.
Stacksync mirrors Campaigns, Broadcasts, Deliveries / Messages, Newsletters from Customer.io into Items, Attributes, Partition and Sort Keys, Global Secondary Indexes in Dynamo DB and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Customer.io, so the tool and the database never disagree.
Common use cases
- Sync account-level objects and their person relationships for B2B messaging keyed to company attributes.
- Sync product usage and billing attributes from Postgres onto Customer.io people so lifecycle campaigns trigger on real product behavior.
- Mirror SaaS objects into DynamoDB items to serve low-latency lookups from production services.
- Consolidate multi-region Global Tables data into a single reporting store.
React to changes as they happen
Updates in Customer.io arrive as row changes in Dynamo DB, so triggers, jobs, and services can respond in near real time.
One integration pattern for the whole stack
Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.
Read Customer.io with a query
Records from Customer.io are ordinary rows in Dynamo DB; join them, index them, and use them in application logic without touching the vendor API.
What you can sync between Customer.io and Dynamo DB
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.
| Customer.io objects | Dynamo DB objects | |
|---|---|---|
| Broadcasts One-off sends to segments or audiences, triggerable via API. | Global Secondary Indexes Alternate access paths used when sync queries filter on non-key attributes. | |
| Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. | DynamoDB Streams Ordered item-level change records consumed for incremental sync. | |
| Newsletters Recurring email sends with performance metrics available for reporting syncs. | Global Tables Multi-region replicas relevant when syncs must read from a specific region. | |
| People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. | Tables The top-level containers a sync targets; each table is addressed independently. | |
| Objects Non-person entities such as accounts or companies, related to people for account-level messaging. | Items Schemaless records keyed by partition (and optional sort) key, mapped to rows or SaaS objects in syncs. | |
| Events Behavioral events sent via the Track API that trigger campaigns. | Attributes Per-item fields, including nested maps and lists, flattened or mapped during sync. |

How the Customer.io and Dynamo DB connectors work
Customer.io
- Integration surface
- REST APIs split by purpose: Track API for data ingestion, App API for campaigns, people lookups, and messages
- Authentication
- Basic auth with site ID and API key for the Track API; bearer token for the App API
- Change detection
- Reporting webhooks push message and delivery events; person attribute changes are not streamed and require source-side detection
- Capabilities
- read · write · webhooks
- Rate limits
- Subject to per-API rate limits documented by Customer.io
Dynamo DB
- Integration surface
- Proprietary JSON-over-HTTPS API accessed through AWS SDKs; PartiQL supported for SQL-like queries
- Authentication
- AWS IAM credentials with SigV4 request signing
- Change detection
- Item-level change streams via DynamoDB Streams or Kinesis Data Streams integration
- Capabilities
- read · write · CDC
- Rate limits
- Throughput is governed by the table's provisioned or on-demand capacity mode

FAQ
Customer.io and Dynamo DB integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Customer.io and Dynamo DB: authenticate both systems, choose the objects to sync (such as Customer.io's Broadcasts and Deliveries / Messages), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
On the Customer.io side: Campaigns, Broadcasts, Deliveries / Messages, Newsletters, plus custom fields where Customer.io exposes them. On the Dynamo DB side: Items, Attributes, Partition and Sort Keys, Global Secondary Indexes. 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 Customer.io and Dynamo DB: React to changes as they happen; One integration pattern for the whole stack; Read Customer.io with a query. Updates in Customer.io arrive as row changes in Dynamo DB, so triggers, jobs, and services can respond in near real time.
-
Customer.io: REST APIs split by purpose: Track API for data ingestion, App API for campaigns, people lookups, and messages. Authentication: Basic auth with site ID and API key for the Track API; bearer token for the App API. Dynamo DB: Proprietary JSON-over-HTTPS API accessed through AWS SDKs; PartiQL supported for SQL-like queries. Authentication: AWS IAM credentials with SigV4 request signing. Stacksync manages authentication, retries, and rate limits on both sides.
-
Customer.io: The Track API is ingestion-oriented: integrations identify people and send events, and Customer.io matches records on identifiers such as id or email. Dynamo DB: DynamoDB Streams records item-level inserts, updates, and deletes in order per partition key, giving a native incremental feed. Stacksync's field mapping accounts for these differences between Customer.io and Dynamo DB without custom code.
