Existing-path check
Verify the current path before changing it.
Before changing a sender, list the outside system, current receiver, intended Shopify Flow trigger, owner, rollback path, evidence source, confidence level, and any access gaps. FlowRelay, Shopify Sidekick, and authorized agents cannot automatically discover every existing webhook app, Zapier or Make scenario, middleware route, serverless function, or receiver unless those systems are available to inspect. If the current environment is incomplete, start with one low-risk event and document what is unknown.
