FAQs

How do I connect this engine to a Klaviyo account? Add your public and private Klaviyo API keys to the credentials file, then restart the service to authenticate automatically.

Does it support multiple brands or stores? Yes — the configuration system allows separate brand profiles with isolated flows, segments, and reporting.

Can I customize flow logic or campaign rules? Absolutely. Every module is modular and supports brand-level overrides for triggers, copy blocks, and segmentation logic.

What happens when a Klaviyo API call fails? The retry layer handles transient failures with exponential backoff and logs each step for transparency.
