Why teams connect Braze and Google Cloud Spanner
Mirror Braze's data into Google Cloud Spanner 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 Braze 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 Google Cloud Spanner.
Stacksync mirrors Custom Events, Purchases, Segments, Campaigns from Braze into Interleaved tables, Secondary indexes, Change streams, Views in Google Cloud Spanner 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 Braze, so the tool and the database never disagree.
Common use cases
- Sync CRM and billing attributes onto Braze user profiles so lifecycle campaigns target accurate plan and status data.
- Push product usage events from a database or warehouse into Braze to trigger onboarding and retention journeys.
- Consolidate data from a globally distributed Spanner deployment into regional business systems.
- Push billing or entitlement changes from finance tools into Spanner tables the application reads at runtime.
React to changes as they happen
Updates in Braze arrive as row changes in Google Cloud Spanner, 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 Braze with a query
Records from Braze are ordinary rows in Google Cloud Spanner; join them, index them, and use them in application logic without touching the vendor API.
What you can sync between Braze and Google Cloud Spanner
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.
| Braze objects | Google Cloud Spanner objects | |
|---|---|---|
| Users The central profile object, identified by external ID, Braze ID, or user aliases; the main sync target. | Change streams Capture inserts, updates, and deletes for log-style change data capture. | |
| Custom Attributes Profile fields written from CRMs, warehouses, and product databases to drive personalization. | Views Read-only projections useful for shaping data before it leaves Spanner. | |
| Custom Events Behavioral events pushed into Braze to trigger campaigns and Canvases. | Databases Top-level containers that scope schema and sync configuration. | |
| Purchases Transaction records logged against profiles for revenue-based targeting. | Tables Relational tables mapped one-to-one to sync targets. | |
| Segments Audience definitions read for membership export and campaign targeting. | Rows The unit of read and write in each sync cycle, keyed by primary key. | |
| Campaigns Message sends whose metadata and analytics are read for reporting. | Interleaved tables Child rows physically co-located with parents; synced as related records. |

How the Braze and Google Cloud Spanner connectors work
Braze
- Integration surface
- REST API
- Authentication
- REST API keys scoped to specific endpoints, issued per workspace
- Change detection
- Braze Currents streams engagement events outward; profile reads otherwise rely on export endpoints and polling
- Capabilities
- read · write
- Rate limits
- Endpoints have per-endpoint rate limits documented by Braze; batch endpoints accept multiple users per request
Google Cloud Spanner
- Integration surface
- gRPC/REST client API with SQL query surface (GoogleSQL and PostgreSQL-interface dialects)
- Authentication
- Google Cloud IAM (service accounts)
- Change detection
- Change streams (log-style CDC), or timestamp-based polling queries
- Capabilities
- read · write · CDC
- Rate limits
- Throughput is bounded by the instance's provisioned compute capacity rather than a fixed API quota.

FAQ
Braze and Google Cloud Spanner integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Braze and Google Cloud Spanner: authenticate both systems, choose the objects to sync (such as Braze's Users and Custom Attributes), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
On the Braze side: Custom Events, Purchases, Segments, Campaigns, plus custom fields where Braze exposes them. On the Google Cloud Spanner side: Interleaved tables, Secondary indexes, Change streams, Views. 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 Braze and Google Cloud Spanner: React to changes as they happen; One integration pattern for the whole stack; Read Braze with a query. Updates in Braze arrive as row changes in Google Cloud Spanner, so triggers, jobs, and services can respond in near real time.
-
Braze: REST API. Authentication: REST API keys scoped to specific endpoints, issued per workspace. Google Cloud Spanner: GRPC/REST client API with SQL query surface (GoogleSQL and PostgreSQL-interface dialects). Authentication: Google Cloud IAM (service accounts). Stacksync manages authentication, retries, and rate limits on both sides.
-
Braze: The users/track endpoint accepts attributes, custom events, and purchases for many users in a single batched request, which is the standard write path for syncs. Google Cloud Spanner: It supports two SQL dialects: GoogleSQL and a PostgreSQL-interface dialect chosen at database creation. Stacksync's field mapping accounts for these differences between Braze and Google Cloud Spanner without custom code.
