gtm-telemetry-wizard

Declarative GTM Container IaC Compiler, Playwright E2E Live Verifier, and GA4 Telemetry Ingestion Setup Wizard.

gtm-telemetry-wizard is a standalone CLI tool and Python library for automating Google Tag Manager (GTM) container setups, compiling declarative IaC specs, verifying live webpage telemetry with Playwright, and warming up GA4 measurement streams to achieve Container Quality: Excellent.

Features

• 5-Phase Setup Wizard: Diagnostic check, container spec compilation, live Playwright verification, GA4 ingest warm-up, and container quality reporting.
• GA4 Ingest Warm-Up: Delivers initial telemetry pings directly to GA4 (/g/collect), automatically clearing 48-hour missing traffic quality alerts.
• Playwright E2E Verification: Headless/Headful browser verification inspecting gtm.js snippet loading, dataLayer events, and UTM parameters.
• Dual Deployment Options: Automated browser import (via Playwright CDP persistent Chrome profile) or GTM REST API v2 deployment.
• Borderless Terminal UI: Clean Rich-powered terminal interface.

Installation

uv tool install gtm-telemetry-wizard

Or install from source:

git clone https://github.com/bizkite-co/gtm-telemetry-wizard.git
cd gtm-telemetry-wizard
uv sync

uv sync installs this checkout as an editable development package. The repository's mise.toml adds .venv/bin to PATH only while working in this directory, so gtw uses the local checkout here and the PyPI installation everywhere else.

Use mise run check to verify the CLI, mise run build to build distributions, and mise run release to create and push the next patch release with verkit.

Campaign Configuration and Provisioning

Every campaign command requires an explicit domain, GTM container ID, and GA4 measurement ID. gtw never substitutes IDs from another campaign. Store those values in the consuming repository's telemetry.toml and pass its location with --config:

gtw wizard --config path/to/telemetry.toml

To create a new GA4 property/web stream and GTM web container, provide the parent account IDs and the configuration path. This writes the returned G-... and GTM-... IDs to that file atomically, ready to review and commit:

gtw provision \
  --domain example.com \
  --analytics-account-id ANALYTICS_ACCOUNT_ID \
  --gtm-account-id GTM_ACCOUNT_ID \
  --config path/to/telemetry.toml

Provisioning uses Application Default Credentials. Before running it, enable the Google Analytics Admin API and Google Tag Manager API, then authenticate with analytics.edit and tagmanager.edit.containers scopes.

Deploy a generated container through the Tag Manager API:

gtw deploy --config path/to/telemetry.toml

Use --no-publish to create a reviewable GTM container version without publishing it.

Quick Start

1. Guided Setup Wizard

Run the 5-phase setup wizard for any website and container ID:

gtw wizard --domain example.com --container-id GTM-XXXXXXX --ga4-id G-YYYYYYYY

2. Using telemetry.toml Configuration File

Create a telemetry.toml in your project directory:

[site]
domain = "example.com"
container_id = "GTM-XXXXXXX"
gtm_container_api_id = "123456789"
ga4_measurement_id = "G-YYYYYYYY"

[deployment]
mode = "browser"
headful = true

Then run:

gtw wizard --config telemetry.toml

Python API Usage

from gtm_telemetry_wizard import TelemetryConfig, TelemetryProvider

# Initialize provider
config = TelemetryConfig(domain="example.com", container_id="GTM-XXXXXXX")
provider = TelemetryProvider(config)

# Run live telemetry verification
results = provider.verify_live_telemetry()
print("GTM Loaded:", results["gtm_script_loaded"])

# Send initial GA4 warm-up ping
ping_res = provider.ping_ga4_measurement_id("G-YYYYYYYY")
print("Ping Status:", ping_res["status"])
