Skill UI

A comprehensive deep dive guide for executing advanced Klaviyo migration strategies. Learn how to move data from legacy v1/v2 APIs, competing Email Service Providers (like Mailchimp), or execute a full platform re-platforming using patterns like the Strangler Fig. Includes technical steps for API field mapping and data transformation.

Provides advanced strategies for managing API rate limits when integrating with Klaviyo. This skill implements robust patterns like exponential backoff, respecting `Retry-After` headers, and utilizing request queuing. It ensures stable, high-throughput data synchronization, preventing 429 errors during large-scale bulk operations.

This reference architecture provides a production-ready, layered structure for integrating external applications with Klaviyo. It outlines best practices for building robust marketing automation systems, including profile synchronization (bidirectional sync), event-driven webhook handlers, background job processing, and implementing middleware like rate limiters. Use this when designing new data pipelines, reviewing project structure, or establishing standardized data synchronization standards for email/SMS campaigns.

A comprehensive guide to implementing production-ready patterns for interacting with the Klaviyo API via the Node.js SDK. This includes best practices for handling singleton sessions, creating type-safe API wrappers, implementing robust retry logic for rate limits, managing cursor-based pagination, and supporting multi-tenant environments. This ensures reliable and maintainable Klaviyo integrations.

A comprehensive guide detailing security best practices for integrating with Klaviyo. Learn how to manage private and public API keys, implement least-privilege scoping for different environments (Dev, Staging, Prod), and critically, how to verify webhook payloads using HMAC-SHA256 signatures. This guide is essential for developers building robust and secure marketing automation pipelines.

This comprehensive guide assists developers in upgrading the klaviyo-api SDK and migrating code between different API revisions (v1/v2 to current REST API). It covers best practices for handling breaking changes, such as switching from ConfigWrapper to ApiKeySession patterns, adjusting property casing (snake_case to camelCase), and updating response access patterns to ensure robust and compliant Klaviyo integrations.

A comprehensive guide to setting up and processing Klaviyo webhooks. This skill covers creating webhook subscriptions via the API, implementing crucial HMAC-SHA256 signature verification for security, and building a robust event handler. Learn how to manage different topic types (e.g., profile updates, list changes) and ensure idempotency, making your application reliable for event-driven marketing integrations.
