Klaviyo Upgrade & Migration
Overview
Guide for upgrading the klaviyo-api SDK, migrating from legacy v1/v2 APIs, and
handling breaking changes between Klaviyo API revisions. The workflow assesses the
current version, surfaces breaking changes with the TypeScript compiler, applies the
matching migration pattern, and ships behind a staging deploy with a clean rollback.
Deep before/after code and the full command sequence live in references/ so this
file stays a scannable map of the workflow:
- Migration patterns — legacy v1/v2 → current API, SDK major upgrade (
ConfigWrapper→ApiKeySession), property casing. - Upgrade & rollback procedure — pinned install, tsc/test gates, staging deploy, rollback, migration checklist.
