## Description

Get the connected user's Google Health identifiers: `healthUserId` and `legacyUserId`, the ID the same user had on the legacy Fitbit Web APIs. Use it to correlate records between a system that stored Fitbit IDs and one now on Google Health. Also the cheapest way to confirm the connection works, since it needs no synced data. Example: call with no parameters → returns `{ healthUserId: "NGL8Q2...", legacyUserId: "2E4RVC" }`. `legacyUserId` is 1-63 characters of letters, numbers and hyphens — treat it as an opaque string and do not assume a fixed length or format. It is empty for users who never had a Fitbit account. [See the documentation](https://developers.google.com/health/reference/rest/v4/users/getIdentity)

## Run it

**MCP**

```ts
import { Client } from "@modelcontextprotocol/sdk/client/index.js"
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp.js"
import { PipedreamClient } from "@pipedream/sdk"

const pd = new PipedreamClient({
  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const accessToken = await pd.rawAccessToken

const transport = new StreamableHTTPClientTransport(
  new URL("https://remote.mcp.pipedream.net/v3"),
  {
    requestInit: {
      headers: {
        Authorization: `Bearer ${accessToken}`,
        "x-pd-project-id": process.env.PIPEDREAM_PROJECT_ID!,
        "x-pd-environment": "production",
        "x-pd-external-user-id": "{external_user_id}", // any stable ID for this user in your system
        "x-pd-app-slug": "google_health",
      },
    },
  },
)

const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)

const { tools } = await mcp.listTools()

// listTools() hands your model this tool's input schema, so it can
// fill the arguments itself:
const result = await mcp.callTool({
  name: "google_health-get-identity",
  arguments: {},
})
```

**TypeScript**

```ts
import { PipedreamClient } from "@pipedream/sdk"

const pd = new PipedreamClient({
  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const result = await pd.actions.run({
  id: "google_health-get-identity",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    google_health: { authProvisionId: "apn_xxxxxxx" },
  },
})

console.log(result)
```
