+## Network Details
+
+_Available in React Native SDK 8.15.0 and later_
+
+By default, Replay captures basic information about all outgoing HTTP requests in your application — URL, request and response body sizes, method, and status code. To limit the chance of collecting private data, request/response **headers** and **bodies** are _not_ captured unless you explicitly opt in.
+
+You opt in by listing the URLs you want enriched in `networkDetailAllowUrls`. Pick only URLs that are safe for capturing bodies and avoid any endpoints that may contain Personally Identifiable Information (PII).
+
+<Alert>
+
+Body and header content will be PII-sanitized server-side, based on object keys and values. Refer to [Server-Side Scrubbing](/security-legal-pii/scrubbing/server-side-scrubbing/) for more details.
+
+</Alert>
+
+<Alert level="warning">
+
+Only **XHR**-based requests are currently supported (this covers `axios` and most popular HTTP clients on React Native). Native `fetch` body capture will be added in a follow-up.
+
+</Alert>
+
+The SDK exposes the following options on `mobileReplayIntegration`:
+
+| Key | Type | Default | Description |
+|-----|------|---------|-------------|
+| `networkDetailAllowUrls` | `(string \| RegExp)[]` | `[]` | URL patterns to enable capture of request/response headers (and bodies, when `networkCaptureBodies` is `true`). String patterns use substring matching; `RegExp` is matched via `.test(url)`. |
+| `networkDetailDenyUrls` | `(string \| RegExp)[]` | `[]` | URL patterns to **never** enable capture for, even if an allow pattern matches them. |
+| `networkCaptureBodies` | `boolean` | `false` | Controls whether request and response bodies are captured for allow-listed URLs. Disabled by default since bodies can contain sensitive payloads &mdash; opt in explicitly. |
+| `networkRequestHeaders` | `string[]` | `[]` | Additional request header names to capture for allow-listed URLs, in addition to the defaults (`Content-Type`, `Content-Length`, `Accept`). |
+| `networkResponseHeaders` | `string[]` | `[]` | Additional response header names to capture for allow-listed URLs, in addition to the defaults (`Content-Type`, `Content-Length`, `Accept`). |
+
+Any URL matching the given pattern(s) will be enriched with headers and (optionally) bodies:
+
+```javascript {tabTitle:Mobile}
+import * as Sentry from "@sentry/react-native";
+
+Sentry.init({
+  dsn: "___PUBLIC_DSN___",
+  replaysSessionSampleRate: 1.0,
+  replaysOnErrorSampleRate: 1.0,
+  integrations: [
+    Sentry.mobileReplayIntegration({
+      networkDetailAllowUrls: ["https://api.example.com"],
+      networkCaptureBodies: true,
+    }),
+  ],
+});
+```
+
+String patterns use substring matching &mdash; any URL containing the string will match. For exact or more complex matches, pass a `RegExp`:
+
+```javascript {tabTitle:Mobile}
+integrations: [
+  Sentry.mobileReplayIntegration({
+    networkDetailAllowUrls: [
+      "api.example.com",                 // substring match
+      /^https:\/\/api\.example\.com\/.*/, // regex match
+    ],
+    networkDetailDenyUrls: [/\/auth\//],  // never capture details for auth endpoints
+    networkCaptureBodies: true,
+  }),
+]
+```
+
+Requests to a matching URL will include request and response bodies (when `networkCaptureBodies` is `true`) as well as the following default headers:
+
+- `Content-Type`
+- `Content-Length`
+- `Accept`
+
+To capture additional headers, configure `networkRequestHeaders` and `networkResponseHeaders`. The defaults are always included:
+
+```javascript {tabTitle:Mobile}
+integrations: [
+  Sentry.mobileReplayIntegration({
+    networkDetailAllowUrls: ["https://api.example.com"],
+    networkCaptureBodies: true,
+    networkRequestHeaders: ["Cache-Control", "X-My-Header"],
+    networkResponseHeaders: ["Referrer-Policy", "X-Response-Header"],
+  }),
+]
+```
+
+<Alert>
+
+Authorization-like headers (`Authorization`, `Cookie`, `Set-Cookie`, `X-API-Key`, `X-Auth-Token`, `Proxy-Authorization`) are always stripped, regardless of configuration. Captured bodies are truncated to ~150 KB; truncated payloads include a `MAX_BODY_SIZE_EXCEEDED` warning. Binary bodies (`Blob`, `ArrayBuffer`, typed arrays) are skipped with an `UNPARSEABLE_BODY_TYPE` warning instead of being inlined.

 ## React Component Names
 
 Sentry helps you capture your React components and unlock additional insights in your application. You can set it up to use React component names.
