# Read available Google fields — HTTP

> Find the metrics and dimensions represented in the stored Google data.

Find the metrics and dimensions represented in the stored Google data.

**Method:** `GET`

**Path:** `/projects/{project_id}/ga4/metadata`

Use the HTTP base for your authorized environment and an `Authorization: Bearer` header. See [authentication](/developers/guides/04-authentication) and [HTTP setup](/developers/guides/06-http-quickstart).

## Parameters

This table covers the standard read profile. It excludes internal application routes and advanced analysis controls.

| Name | Location | Type | Required | Default | Meaning |
| - | - | - | - | - | - |
| `project_id` | path | string | Yes | — | Project ID from list\_projects. Select the project in the intended workspace and environment. |

## Request example

Set `IQRUSH_API_BASE` and `IQRUSH_ACCESS_TOKEN` through secure configuration. Replace project/run IDs and sample selections with values returned by your account. JSON objects and arrays are encoded as query strings.

```bash theme={null}
curl --fail-with-body --silent --show-error --get \
  --header "Authorization: Bearer ${IQRUSH_ACCESS_TOKEN}" \
  --header "Accept: application/json" \
  "${IQRUSH_API_BASE%/}/projects/${IQRUSH_PROJECT_ID}/ga4/metadata"
```

## Read the response

Returns `linked`, `dimensions`, and `metrics`, including field names and descriptions when linked.

The metadata describes the available store. The report tool does not accept arbitrary dimensions and metrics as a generic Google API request.

### Fields to use

These selected fields explain the example and the result to preserve. Field presence depends on the response; this is not a complete response schema.

| Field | Meaning and use |
| - | - |
| `linked` | Whether a property link exists. |
| `dimensions` | Available dimension metadata. The observed unlinked response contains no entries. |
| `metrics` | Available metric metadata. An empty list is not a report of zero measurement values. |

Selected response fields from IQRush Dev. Lists are shortened and project/run IDs are placeholders; this is not the full response.

```json theme={null}
{
  "project_id": "PROJECT_ID",
  "linked": false,
  "dimensions": [],
  "metrics": []
}
```

This observed example has no linked Google property. It demonstrates the unavailable-integration response; it is not a zero-traffic report.

MCP equivalent: [`get_ga4_metadata`](/developers/tools/get_ga4_metadata). Use the parameters and defaults on this page for HTTP.

## If the result is unavailable

Check HTTP status and the response’s `error` field before using data. A successful empty response does not establish a zero value. Preserve `not_available`, `not_available_reason`, `unavailable_reason`, and `linked` where returned. [Errors and recovery](/developers/guides/13-errors) shows observed examples.
