# Datadog (OAuth)

> Integrate your application with the Datadog API using OAuth

## 🚀 Quickstart

Connect to Datadog with Nango and see data flow in 2 minutes.

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

  <Step title="Authorize Datadog">
    Go to [Connections](https://app.nango.dev/dev/connections) -> *Add Test Connection* -> *Authorize*, then select your Datadog site and log in. Later, you'll let your users do the same directly from your app.
  </Step>

  <Step title="Call the Datadog API">
    Let's make your first request to the Datadog API (list events). Replace the placeholders below with your [secret key](https://app.nango.dev/dev/environment-settings), [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/v1/events" \
          -H "Authorization: Bearer <NANGO-SECRET-KEY>" \
          -H "Provider-Config-Key: <INTEGRATION-ID>" \
          -H "Connection-Id: <CONNECTION-ID>"
        ```
      </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({ secretKey: '<NANGO-SECRET-KEY>' });

        const res = await nango.get({
            endpoint: '/v1/events',
            providerConfigKey: '<INTEGRATION-ID>',
            connectionId: '<CONNECTION-ID>'
        });

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

    Or fetch credentials with the [Node SDK](/reference/sdks/node#get-a-connection-with-credentials) or [API](/reference/api/connection/get).

    ✅ 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](/guides/primitives/auth) to integrate Nango in your app.

    To obtain your own production credentials, follow the setup guide linked below.

## 🧩 Pre-built syncs & actions for Datadog (OAuth)

Enable them in your dashboard. Extend and customize to fit your needs.

*No pre-built syncs or actions available yet.*

<Tip>Not seeing the integration you need? [Build your own](/guides/functions/functions-guide) independently.</Tip>

## API gotchas

* Datadog's OAuth authorize and token endpoints, and its API base URL, are all site-specific — pick the site matching where your users' Datadog accounts live (for example `datadoghq.com` for US1, `datadoghq.eu` for EU1). A token issued on one site won't work against another site's API.
* Grant only the scopes your app actually needs when creating your OAuth client — Datadog enforces the principle of least privilege, and any request against a scope you didn't request returns a 401 even with a valid, unexpired token. See [Authorization scopes for OAuth clients](https://docs.datadoghq.com/api/latest/scopes/) for the full list.
* To send data on behalf of a connected user (rather than just reading it), you need a Datadog API key. Call the [API Key Creation endpoint](https://docs.datadoghq.com/api/latest/key-management/#create-an-api-key) with the `API_KEYS_WRITE` scope — the generated key is only ever shown once, so store it securely.
