Resolution

There is no technical limitation preventing the use of Subresource Integrity (SRI) on the Engagement Engine script. However, it’s important to understand the operational implications. The Engagement Engine script is periodically updated to deliver product improvements, bug fixes, and new features. Any modification to the script, even minor, will invalidate the previously generated integrity hash.

If SRI is enabled and the script changes, the browser will reject the resource because the hash no longer matches. In such cases, you will need to generate and deploy an updated integrity hash to ensure the script continues to load correctly. This means SRI can be used, but requires ongoing maintenance to keep the hash in sync with script updates.

Please be aware that Engagement Engine does not follow a fixed or pre-announced release schedule. As a result, customers will not receive advance notification of updates that may modify the script and invalidate any previously configured SRI hashes.
