Why teams connect Google Cloud Platform and Kustomer

Sync Kustomer into Google Cloud Platform continuously and push warehouse results back onto CRM records, one two-way connection instead of two pipelines.

The CRM feeds the warehouse and the warehouse should feed the CRM: relationship data flows one way, and computed scores, segments, and customer context flow back. Most teams build the first half as a batch pipeline and never quite get to the second.

Stacksync does both with one connection. Notes, Customers, Conversations, Messages from Kustomer land in Google Cloud Platform as live tables, updated within seconds, and columns computed in Google Cloud Platform write back to fields in Kustomer. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • 01 Keep customer attributes updated from billing systems so routing rules and SLAs reflect account value
  • 02 Escalate conversation-derived signals into the CRM as tasks or opportunities
  • 03 Publish change events to Pub/Sub so downstream services react to record updates as they happen.

Common sync patterns

Scores and segments back on the record

Lead scores, churn risk, or usage segments computed in Google Cloud Platform appear as fields in Kustomer, where the people working accounts actually see them.

A single customer view

Join Kustomer's relationship data with billing, product, and support data in Google Cloud Platform to build the customer picture the CRM alone cannot hold.

Cleanup that sticks

Deduplication and normalization done in Google Cloud Platform can be written back, so warehouse-side cleanup actually fixes the CRM.

What you can sync between Google Cloud Platform and Kustomer

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.

Google Cloud Platform objects Kustomer objects How this pairing syncs
BigQuery datasets Namespaces that group tables; syncs target tables within a dataset. Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline. BigQuery datasets is specific to Google Cloud Platform and Custom Objects (Klasses) to Kustomer — each maps to any object or custom field on the other side.
BigQuery tables The primary analytics destination, written through load jobs or the Storage Write API and queried with SQL. Users Agent records map conversation ownership to people in other systems. BigQuery tables is specific to Google Cloud Platform and Users to Kustomer — each maps to any object or custom field on the other side.
Cloud SQL databases Managed Postgres, MySQL, and SQL Server instances synced like ordinary relational databases. Teams Team assignments support routing parity and reporting. Cloud SQL databases is specific to Google Cloud Platform and Teams to Kustomer — each maps to any object or custom field on the other side.
Cloud Storage objects Staging area for file-based bulk loads into BigQuery and other services. Tags Labels on conversations and customers sync for categorization and analytics. Cloud Storage objects is specific to Google Cloud Platform and Tags to Kustomer — each maps to any object or custom field on the other side.
Pub/Sub topics Event streams used to move change events between systems in near real time. Notes Internal annotations carry context alongside synced conversations. Pub/Sub topics is specific to Google Cloud Platform and Notes to Kustomer — each maps to any object or custom field on the other side.
Firestore documents Document data read and written through the Firestore API for app-facing syncs. Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. Firestore documents is specific to Google Cloud Platform and Customers to Kustomer — each maps to any object or custom field on the other side.

How changes propagate between Google Cloud Platform and Kustomer

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.

Google Cloud Platform Kustomer Sub-second propagation

DetectionGoogle Cloud Platform pushes changes as they happen — webhook events backed by change data capture. Varies by service: log-based CDC on Cloud SQL (logical replication or binlog, also via Datastream), Pub/Sub for event delivery, polling for BigQuery.

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

Kustomer Google Cloud Platform Sub-second propagation

DetectionKustomer notifies Stacksync of record changes through webhook events. Outbound webhooks on record events, plus polling for backfill.

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

Rate-limit considerations

  • Google Cloud Platform: Quotas are set per service and per project; BigQuery, Pub/Sub, and Cloud SQL each enforce their own limits.
  • Kustomer: Subject to the platform's API rate limits.
