# PostHog (Capture API)

> Send events to PostHog using the public capture API and a project token

## 🚀 Quickstart

Connect to PostHog's Capture API with Nango and send your first event in 2 minutes. This uses a **Project Token** (`phc_...`), not a personal API key — the capture API is a public, write-only endpoint with no identity validation, so no user login is required.

<Steps>
  <Step title="Create an integration">
    In Nango ([free signup](https://app.nango.dev)), go to [Integrations](https://app.nango.dev/dev/integrations) -> *Configure New Integration* -> *PostHog (Capture API)*.
  </Step>

  <Step title="Authorize PostHog">
    Go to [Connections](https://app.nango.dev/dev/connections) -> *Add Test Connection* -> *Authorize*, then enter your **Hostname** (e.g. `us.i.posthog.com`) and **Project Token**. Later, you'll let your users do the same directly from your app.
  </Step>

  <Step title="Send your first event">
    Let's send a test event via the capture API. Replace the placeholders below with your [Environment API key](/docs/reference/backend/http-api/api-keys), [integration ID](https://app.nango.dev/dev/integrations), and [connection ID](https://app.nango.dev/dev/connections):

    <Tabs>
      <Tab title="cURL">
        ```bash theme={null}
        curl "https://api.nango.dev/proxy/i/v0/e/" \
          -X POST \
          -H "Authorization: Bearer <NANGO-API-KEY>" \
          -H "Provider-Config-Key: <INTEGRATION-ID>" \
          -H "Connection-Id: <CONNECTION-ID>" \
          -H "Content-Type: application/json" \
          -d '{"event": "test-event", "distinct_id": "test-user-123"}'
        ```
      </Tab>

      <Tab title="Node">
        Install Nango's backend SDK with `npm i @nangohq/node`. Then run:

        ```typescript theme={null}
        import { Nango } from '@nangohq/node';

        const nango = new Nango({ apiKey: '<NANGO-API-KEY>' });

        const res = await nango.post({
            endpoint: '/i/v0/e/',
            data: { event: 'test-event', distinct_id: 'test-user-123' },
            providerConfigKey: '<INTEGRATION-ID>',
            connectionId: '<CONNECTION-ID>'
        });

        console.log(res.data);
        ```
      </Tab>
    </Tabs>

    Nango automatically adds your stored **Project Token** as the `api_key` field in the request body — you only need to supply `event` and `distinct_id` (plus any `properties` you want).

    ✅ You're connected! Check the [Logs](https://app.nango.dev/dev/logs) tab in Nango to inspect requests.
  </Step>

  <Step title="Implement Nango in your app">
    Follow our [Auth implementation guide](/docs/guides/primitives/auth) to integrate Nango in your app.

## 📚 PostHog (Capture API) Integration Guides

* [How do I link my PostHog account?](/docs/api-integrations/posthog-capture/connect)\
  Connect your PostHog account using the Connect UI (hostname and Project Token)

<Note>
  Need PostHog's general analytics/query API instead (reading data, not sending events)? Use the [PostHog](/docs/api-integrations/posthog) integration, which authenticates with a personal API key.
</Note>
