Google Analytics Reporting Python API Docs | dltHub

Google Analytics Reporting API provides programmatic access to report data from Google Analytics accounts. The REST API base URL is https://analyticsreporting.googleapis.com/ and all requests require an OAuth 2.0 Bearer token.

dlt is an open-source Python library that handles authentication, pagination, and schema evolution automatically. dlthub provides AI context files that enable code assistants to generate production-ready pipelines. Install with uv add "dlt[hub]" and start loading Google Analytics Reporting data in under 10 minutes.

What data can I load from Google Analytics Reporting?

Here are some of the endpoints you can load from Google Analytics Reporting:

How do I authenticate with the Google Analytics Reporting API?

Authentication is performed using OAuth 2.0. Requests require an Authorization header with a Bearer token, which is typically obtained via service accounts or user-authorized OAuth flows.

1. Get your credentials

To obtain credentials for the Google Analytics Reporting API (specifically the GA4 Data API), follow these steps in the Google Cloud Console: 1. Select or create a Google Cloud project. 2. Enable the 'Google Analytics Data API' (analyticsdata.googleapis.com). 3. Navigate to APIs & Services > Credentials. 4. Choose either 'Create Credentials' > 'Service Account' for server-to-server access (recommended for production) or 'OAuth 2.0 Client ID' for user-based access. 5. If using a service account, download the resulting JSON key file. 6. In your Google Analytics property (GA4), add the service account email address as a user with at least 'Viewer' permissions.

2. Add them to .dlt/secrets.toml

Copy
[sources.google_analytics_reporting_source]
project_id = "your_project_id"
client_email = "your_service_account_email"
private_key = "-----BEGIN PRIVATE KEY-----\n...\n-----END PRIVATE KEY-----\n"

dlt reads this automatically at runtime — never hardcode tokens in your pipeline script. For production environments, see setting up credentials with dlt for environment variable and vault-based options.

How do I set up and run the pipeline?

Set up a virtual environment and install dlt:

Copy
uv init
uv add "dlt[hub]"

1. Install the dlt AI harness:

Copy
uv run dlthub ai init --agent <your-agent> # <agent>: claude | cursor | codex

This installs project rules, a secrets management skill, appropriate ignore files, and configures the dlt MCP server for your agent. Learn more →

2. Install the rest-api-pipeline toolkit:

Copy
uv run dlthub ai toolkit install rest-api-pipeline

This loads the skills and context about dlt the agent uses to build the pipeline iteratively, efficiently, and safely. The agent uses MCP tools to inspect credentials — it never needs to read your secrets.toml directly. Learn more →

3. Start LLM-assisted coding:

Use /find-source to load data from the Google Analytics Reporting API into DuckDB.

The rest-api-pipeline toolkit takes over from here — it reads relevant API documentation, presents you with options for which endpoints to load, and follows a structured workflow to scaffold, debug, and validate the pipeline step by step.

4. Run the pipeline:

Copy
uv run python google_analytics_reporting_pipeline.py

If everything is configured correctly, you'll see output like this:

Copy
Pipeline google_analytics_reporting_pipeline load step completed in 0.26 seconds
1 load package(s) were loaded to destination duckdb and into dataset google_analytics_reporting_data
The duckdb destination used duckdb:/google_analytics_reporting.duckdb location to store data
Load package 1749667187.541553 is LOADED and contains no failed jobs

Inspect your pipeline and data:

Copy
uv run dlthub show

This opens the Pipeline Dashboard where you can verify pipeline state, load metrics, schema (tables, columns, types), and query the loaded data directly.

Python pipeline example

This example loads v1beta/properties/{property}

and v1/reports from the Google Analytics Reporting API into DuckDB. It mirrors the endpoint and data selector configuration from the table above:

Copy
import dlt
from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources

@dlt.source
def google_analytics_reporting_source(credentials=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://analyticsreporting.googleapis.com/",
            "auth": {"type": "bearer", "token": credentials},
        },
        "resources": [
            {"name": "run_report", "endpoint": {"path": "v1beta/{property=properties/*}:runReport", "data_selector": "rows"}},
            {"name": "run_pivot_report", "endpoint": {"path": "v1beta/{property=properties/*}:runPivotReport", "data_selector": "rows"}}
        ],
    }
    yield from rest_api_resources(config)


def get_data() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="google_analytics_reporting_pipeline",
        destination="duckdb",
        dataset_name="google_analytics_reporting_data",
    )
    load_info = pipeline.run(google_analytics_reporting_source())
    print(load_info)

To add more endpoints, append entries from the resource table to the "resources" list using the same name, path, and data_selector pattern.

How do I query the loaded data?

Once the pipeline runs, dlt creates one table per resource. You can query with Python or SQL.

Python (pandas DataFrame):

Copy
import dlt

data = dlt.pipeline("google_analytics_reporting_pipeline").dataset()
sessions_df = data.run_report.df()
print(sessions_df.head())

SQL (DuckDB example):

Copy
SELECT * FROM google_analytics_reporting_data.run_report LIMIT 10;

In a marimo or Jupyter notebook:

Copy
import dlt

data = dlt.pipeline("google_analytics_reporting_pipeline").dataset()
data.run_report.df().head()

See how to explore your data in marimo Notebooks and how to query your data in Python with dataset.

What destinations can I load Google Analytics Reporting data to?

dlt supports loading into any of these destinations — only the destination parameter changes:

Change the destination in dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. See the full destinations list.
