+---
+
+The OTLP integration configures the Sentry SDK to automatically send trace data instrumented by an OpenTelemetry SDK to Sentry's [OpenTelemetry Protocol](https://opentelemetry.io/docs/specs/otel/protocol/) [ingestion endpoint](/concepts/otlp).
+
+## Install
+
+Install `sentry-sdk` from PyPI with the `opentelemetry-otlp` extra.
+
+```bash {tabTitle:pip}
+pip install "sentry-sdk[opentelemetry-otlp]"
+```
+```bash {tabTitle:uv}
+uv add "sentry-sdk[opentelemetry-otlp]"
+```
+
+## Configure
+
+You need to configure both the OpenTelemetry and Sentry SDKs to get trace data.
+
+### OpenTelemetry
+
+For the OpenTelemetry SDK, you need to [configure instrumentation](https://opentelemetry.io/docs/languages/python/getting-started/#instrumentation) you want to capture.
+
+### Sentry
+
+For the Sentry SDK, you simply need to enable our `OTLPIntegration` along with your existing configuration.
+
+<OnboardingOptionButtons
+  options={["error-monitoring", "logs"]}
+/>
+
+```python
+import sentry_sdk
+from sentry_sdk.integrations.otlp import OTLPIntegration
+
+sentry_sdk.init(
+    dsn="___PUBLIC_DSN___",
+    # Add data like request headers and IP for users, if applicable;
+    # see https://docs.sentry.io/platforms/python/data-management/data-collected/ for more info
+    send_default_pii=True,
+    # ___PRODUCT_OPTION_START___ logs
+    # Enable logs to be sent to Sentry
+    enable_logs=True,
+    # ___PRODUCT_OPTION_END___ logs
+    integrations=[
+        OTLPIntegration(),
+    ],
+)
+```
+
+## Behavior
+
+Under the hood, the `OTLPIntegration` will setup the following parts:
+
+* A [`SpanExporter`](https://opentelemetry.io/docs/concepts/components/#exporters) that will automatically setup the OTLP ingestion endpoint from your Sentry DSN. This enables tracing in Sentry. **Note:** _Do not_ also set up tracing via the Python SDK. 
+* A [`Propagator`](https://opentelemetry.io/docs/concepts/context-propagation/#propagation) that ensures [distributed tracing](/concepts/key-terms/tracing/distributed-tracing/) works
+* Trace/Span linking for all other Sentry events such as Errors, Logs, Crons and Metrics
+
+## Supported Versions
+
+- Python: 3.7+
+- opentelemetry-distro: 0.35b0+

+We now have a dedicated <PlatformLink to="/integrations/otlp"> OTLPIntegration</PlatformLink> that can directly ingest OpenTelemetry Traces into Sentry. We recommend moving over to the new setup since it is much simpler.

 You can configure your [OpenTelemetry SDK](https://opentelemetry.io/) to send traces and spans to Sentry.
