    "incantation": "When the app hosts the Flow trigger lifecycle callback, set its `url` to a single-slash relative path; Shopify CLI resolves it against the dev tunnel during `app dev` and the HTTPS `application_url` during deploy. Implement the callback route, run `shopify app dev` and create a workflow using the trigger, then run `shopify app deploy`.",
    "examples": [
      "[[extensions]]\nname = \"My lifecycle callback\"\nhandle = \"my-lifecycle-callback\"\ntype = \"flow_trigger_lifecycle_callback\"\nuid = \"<generated-uid>\"\nurl = \"/flow/lifecycle-callback\"",

    "gotchas": [
      "Version: 4.9.0",
      "url (required): Callback endpoint; use an absolute HTTPS URL or a relative path starting with one `/`. Relative paths resolve against the dev tunnel during `app dev` and `application_url` during deploy; the server must respond within five seconds with a `2xx` status.",
      "application_url (required): App configuration URL. Must be HTTPS when `url` is relative, so the path resolves to an HTTPS URL during deploy.",
      "Prerequisite: For a relative callback path, set an HTTPS `application_url` before deploying.",
      "Prerequisite: Configure the web server to receive the callback, verify its `x-shopify-hmac-sha256` header using the app client secret, and respond within five seconds.",
      "Prerequisite: Run `shopify app dev` from the app directory and select a dev store if prompted.",
      "Applies to Flow trigger lifecycle callback extensions.",
      "A corresponding route file must exist in `/app/routes`."
