Digital platform for actors

I’m looking to wire Screen Test (https://screentest.online/) into my Shalash instance (https://staging.shalash.org.il/) so every time a chosen event fires in Shalash, a Screen Test run is launched automatically and its pass/fail result is returned to the same flow.

The work involves:
• Exposing or consuming the right web-hooks / REST endpoints on both sides
• Defining a simple payload that tells Screen Test which baseline set and viewport to use
• Returning the diff report or status code back to Shalash so it can continue the automation chain (e.g., alerting, rollback, or log entry)

All API keys, existing test suites, and event definitions are ready for you; what I need is the connective tissue plus a brief README so I can add new events or screen sets later without touching code.

A good deliverable for me is:
1. Source code (preferably TypeScript/Node, but I’m open) pushed to a Git repo of mine
2. One sample Shalash trigger configured and documented
3. A short video or GIF proving the round-trip: event → Screen Test → result routed back

If you have handled webhook-driven QA automation before, this should be quick; please tell me in a sentence or two how you’d architect the callback flow and we’re good to go.
