Klaviyo Python SDK
Decision gist · record as of 2026-08-14
Yes. The SDK is actively maintained, has no known vulnerabilities, and low install friction. It is the canonical way to integrate Klaviyo's API into Python applications. Use it if you are building Klaviyo integrations, automating marketing workflows, or syncing customer data. The permissive MIT license poses no compliance risk.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a valid Klaviyo API key; SDK retries on rate limits and server errors with configurable max_delay and max_retries.
- Low friction installation with stable maintenance.
- Released 30 days ago with active repository status and no known vulnerabilities.

What it is and what it does
This is the official Python SDK for Klaviyo's marketing API, providing a thin wrapper around Klaviyo's REST endpoints. It mirrors the API's resource organization (Accounts, Campaigns, Catalogs, Events, Flows, Profiles, Segments, Tags, Templates, and others) and handles common concerns like automatic retries on rate limits and server errors, pagination via cursor-based navigation, and filtering/sorting via JSON API conventions.
The SDK is designed for developers integrating Klaviyo into Python applications—sending events, managing customer profiles, querying metrics, creating campaigns, and accessing related resources. It supports advanced features like datetime filtering, sparse fieldsets, relationship endpoints, and image uploads. Error handling is explicit via ApiException, which exposes status, reason, body, and headers for debugging.
Use it for
- Track customer events (purchases, page views, form submissions) to Klaviyo for segmentation and campaign targeting.
- Query and update customer profiles in bulk, including predictive analytics fields and list memberships.
- Retrieve campaign performance metrics and reporting data for analytics dashboards.
- Build segments based on filtered profile data and datetime ranges, then manage associated tags and campaigns.
- Upload images and manage marketing assets programmatically within Klaviyo.
- Automate flow and template management, including creating and publishing campaigns at scale.
