Why teams connect GitHub and Klaviyo
Stop re-entering the same information in GitHub and Klaviyo: Stacksync keeps the records they share consistent in real time, in both directions.
Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.
Stacksync syncs Commits, Releases, Workflow runs (Actions), Organizations and Teams in GitHub with Profiles, Lists, Segments, Events in Klaviyo in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.
Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.
Common use cases
- Sync organization and team membership with an identity or HR system to automate access reviews and offboarding.
- Create GitHub issues automatically from records written elsewhere, such as bug reports logged in a CRM case object.
- Push offline, ERP, or subscription order events into Klaviyo as metrics to trigger post-purchase and win-back flows
- Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data
Handoffs between teams
When work started in one tool continues in the other, the shared fields travel with it automatically.
Where both tools track people or companies: one consistent record
Contact and company details corrected in either tool update the other, so nobody works from the old version.
Where one tool produces events: mirror them in the other
Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.
What you can sync between GitHub and Klaviyo
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.
| GitHub objects | Klaviyo objects | |
|---|---|---|
| Pull Requests Review state, status checks, and merge status feed engineering dashboards and workflow tools. | Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows. | |
| Commits Read-only history used to link code activity to tickets and releases. | Metrics Event type definitions organize the activity stream used in segmentation and attribution. | |
| Releases Tagged versions synced into changelogs, CRMs, or customer-notification systems. | Campaigns Email and SMS sends expose performance data for warehouse-based reporting. | |
| Workflow runs (Actions) CI results synced into incident and reporting systems. | Flows Automation definitions and their engagement data sync outward for attribution. | |
| Organizations and Teams Membership data synced with identity systems and HR directories for access reviews. | Templates Message templates are accessible via API for content management workflows. | |
| Users Author and assignee identities matched to internal directories. | Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers. |

FAQ
GitHub and Klaviyo integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between GitHub and Klaviyo: authenticate both systems, choose the objects to sync (such as GitHub's Pull Requests and Commits), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
GitHub: GitHub Apps authenticate with short-lived installation tokens scoped to specific repositories and permissions, which suits least-privilege sync setups. Klaviyo: Profiles accept arbitrary custom properties, and events are append-only records tied to named metrics, which together form the segmentation model external data is synced into. Stacksync's field mapping accounts for these differences between GitHub and Klaviyo without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means GitHub and Klaviyo records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed GitHub and Klaviyo connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom GitHub–Klaviyo integration in-house.
-
Yes — Stacksync ships production-grade connectors for both GitHub and Klaviyo. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on GitHub: Webhooks with a broad event catalog covering issues, pull requests, pushes, and releases; polling for backfill. On Klaviyo: Polling on updated timestamps; outbound webhooks exist for event topics (availability depends on plan or app-partner status) and as flow webhook actions. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
