# Export to Sentry

Last updated Oct 2, 2026|Copy as Markdown| [View as Markdown](https://developers.cloudflare.com/observability/export/opentelemetry/sentry/index.md)| [Agent setup](https://developers.cloudflare.com/agent-setup/)

Sentry provides distributed tracing, logs, and application monitoring. Export Cloudflare telemetry to query data and create alerts or dashboards.

This guide configures Sentry to receive Cloudflare traces and logs.

## Prerequisites

Before you begin, you need an active [Sentry account ↗︎](https://sentry.io/signup/). You also need Cloudflare logs or traces to export.

## 1. Create a Sentry project

Skip this step if you already have a project.

1. Log in to your [Sentry account ↗︎](https://sentry.io/).
2. Go to **Insights** > **Projects**.
3. Select [**New Project** ↗︎](https://sentry.io/orgredirect/organizations/:orgslug/insights/projects/new/).
4. Complete the project form, then select **Create Project**.

## 2. Get your Sentry OTLP endpoints

Sentry provides separate OpenTelemetry Protocol (OTLP) endpoints for traces and logs:

- **Traces**: `https://<HOST>/api/<PROJECT_ID>/integration/otlp/v1/traces`
- **Logs**: `https://<HOST>/api/<PROJECT_ID>/integration/otlp/v1/logs`

1. In Sentry, go to [**Settings** > **Projects** ↗︎](https://sentry.io/orgredirect/organizations/:orgslug/settings/projects/).
2. Select your project.
3. Under **SDK Setup**, select **Client Keys (DSN)**.
4. Copy the OTLP endpoints and authentication header.

For endpoint details, refer to [Sentry OTLP documentation ↗︎](https://docs.sentry.io/concepts/otlp/).

## 3. Configure Cloudflare Observability destinations

In the Cloudflare dashboard, go to **Observability** > **Destinations**.

[Go to **OpenTelemetry** ↗](https://dash.cloudflare.com/?to=/:account/observability/destinations)

### Configure a traces destination

1. Select **Add destination**.
2. Configure the destination:
   - **Destination name**: `sentry-traces`
   - **Destination type**: *Traces*
   - **OTLP endpoint**: Your Sentry OTLP traces endpoint
   - **Custom header name**: `x-sentry-auth`
   - **Custom header value**: `sentry sentry_key=<SENTRY_PUBLIC_KEY>`
3. Select **Save**.

### Configure a logs destination

1. Select **Add destination**.
2. Configure the destination:
   - **Destination name**: `sentry-logs`
   - **Destination type**: *Logs*
   - **OTLP endpoint**: Your Sentry OTLP logs endpoint
   - **Custom header name**: `x-sentry-auth`
   - **Custom header value**: `sentry sentry_key=<SENTRY_PUBLIC_KEY>`
3. Select **Save**.

## 4. Enable export

Creating a destination does not start exporting telemetry. To export [Workers Logs](https://developers.cloudflare.com/workers/observability/logs/workers-logs/) or [Workers Traces](https://developers.cloudflare.com/workers/observability/traces/), [configure OpenTelemetry export for your Worker](https://developers.cloudflare.com/workers/observability/opentelemetry-export/). To export [Cloudflare Traces](https://developers.cloudflare.com/observability/traces/), [configure export for your domain](https://developers.cloudflare.com/observability/traces/configuration/#export-traces).

Data may take several minutes to appear in Sentry.
