+title: HTTPX2
+description: "Learn about the HTTPX2 integration and how it adds support for the HTTPX2 HTTP client."
+---
+
+The [HTTPX2](https://httpx2.pydantic.dev/) integration instruments outgoing HTTP requests using either the sync or the async HTTPX2 clients.
+
+Use this integration to create spans for outgoing requests and ensure traces are properly propagated to downstream services.
+
+## Install
+
+Install `sentry-sdk` from PyPI:
+
+```bash {tabTitle:pip}
+pip install sentry-sdk
+```
+```bash {tabTitle:uv}
+uv add sentry-sdk
+```
+
+## Configure
+
+The HTTPX2 integration is enabled automatically if you have the `httpx2` package installed.
+
+<PlatformContent includePath="getting-started-config" />
+
+## Verify
+
+```python
+import httpx2
+
+def main():
+    sentry_init(...)  # same as above
+    with sentry_sdk.start_transaction(name="testing_sentry"):
+        r1 = httpx2.get("https://sentry.io/")
+        r2 = httpx2.post("http://httpbin.org/post")
+
+main()
+```
+
+This will create a transaction called `testing_sentry` in the Performance section of [sentry.io](https://sentry.io), and create spans for the outgoing HTTP requests.
+
+It takes a couple of moments for the data to appear in [sentry.io](https://sentry.io).
+
+## Supported Versions

+- HTTPX2: 2.0+
