We are looking for a way to optimize the very long loading time of some service portal pages that involve invoking several 3rd party APIs (through server side outbound Rest Messages - i.e. via sn_ws.RESTMessageV2) to retrieve data to be processed and displayed in the portal.
We already applied strategies of async loading of page sections, but to improve further we would need to call several APIs at the same time, and this is currently our architectural goal.
I already reviewed KB0755706 that specifies that each user can engage only one platform transaction at the same time, and also an old community post that had the same answer.
We are now wondering if the introduction of Web Components for the UI Framework on Next Experience is changing this limitation in any way, or if any workaround not involving a 3rd system between our ServiceNow and the API platform could be implemented. Since we are starting the study phase of UI Framework it would be useful to adjust our architecture from the start.
Thanks in advance for any useful contribution!
