Commercetools + Optimizely integration for faster, safer A/B testing at scale
Connect Commercetools with Optimizely to run server-side experiments, personalize key journeys, and measure uplift with clean event data across your composable stack.

• Optimizely’s decisioning determines the visitor’s variant and returns it to the Commercetools-based storefront via SDK/API calls, with the storefront rendering the correct experience.
• Commerce events such as product views, add-to-cart, checkout start, and purchases are sent from the storefront to Optimizely for experiment attribution, with order identifiers and values mapped consistently.
• User identifiers are handled through cookies or authenticated IDs, allowing audience targeting and experiment consistency across sessions where identity is available.
• Experiment configuration is owned in Optimizely, while catalog, pricing, inventory, carts, and orders remain owned by Commercetools, limiting write operations to the commerce backend.
• Feature flags and experiments are evaluated at runtime, with fallback behavior applied when Optimizely is unavailable or a visitor is not bucketed.
• Event payloads and API responses are logged for troubleshooting, with validation on required fields (currency, locale, and transaction totals) to prevent polluted reporting.

Why choose scandiweb to handle Commercetools integration for you?
How do you connect Commercetools with Optimizely for server-side A/B testing on a headless storefront?
We wire Optimizely decisioning into your storefront or edge layer and pull the right commerce context from Commercetools APIs. This keeps experiments fast while Commercetools remains the source of truth for pricing, inventory, and orders.
What Commercetools data should be sent to Optimizely to measure revenue uplift and conversion accurately?
Send stable identifiers and key commerce events like product views, add to cart, checkout steps, and purchases, plus values like revenue and currency. We also align event naming and deduping so results match your BI and GA4.
Can the Commercetools + Optimizely integration support multistore, multiple locales, and separate brand catalogs?
Yes, experiments can be scoped by locale, currency, channel, or project, and audiences can be segmented using the same context. We set guardrails so variants do not leak across stores or markets.
How do you run Optimizely experiments on Commercetools checkout and pricing flows without breaking compliance?
We limit what can change in sensitive steps, use feature flags for safe rollouts, and add QA checks for tax, payment, and order integrity. For higher-risk tests, we stage with holdouts and rollback paths.
Why choose scandiweb for a Commercetools Optimizely integration project?
We have delivered 2,100+ eCommerce projects since 2003, and our teams cover Commercetools builds, analytics, and experimentation under one roof. That means faster implementation, cleaner measurement, and fewer handoffs.
