The shift from Universal Analytics to Google Analytics 4 (GA4) has introduced a range of advanced features that transform both website analytics and app analytics.

However, users have encountered notable challenges when working with the GA4 API, particularly in integrating data with tools like Google BigQuery and Looker Studio (formerly Google Data Studio).

Understanding the limitations of the GA4 API and exploring practical solutions is essential for businesses looking to maintain smooth data workflows and the continued effective use of analytics tools.

In this article, we delve into the key obstacles users face and how to overcome them to ensure effective use of GA4's powerful analytics capabilities.

Note: This post was originally published in February 2016 to specify the advantages, benefits, and challenges of Google Analytics API and was completely updated in September 2024 for accuracy and comprehensiveness regarding Google Analytics 4 API.

What is Google Analytics (GA4) 4 API?

The GA4 API, also known as the Google Analytics Data API, is a native tool that grants programmatic access to reports data from Google Analytics 4.

The significance of the API Google Analytics 4 lies in its advanced features and its role in the transition from Universal Analytics, offering remarkable opportunities for in-depth analysis of user interactions across various platforms, including websites, iOS, and Android apps in third-party tools (e.g. data visualization with Looker Studio by Google) based on GA4 data.

Consider the types of insights you can get with the GA4 API. For instance, you could generate a report detailing the number of views each of the top 10 URLs on your website received over the past 365 days. Or, you might analyze the daily active users on your IOs application over the previous week.

This API isn’t just limited to getting custom reports data. Its versatility extends to using the data to craft personalized dashboards, automating report generation, and integrating analytics data with other business tools for a more comprehensive view.

On the technical front, leveraging the API involves executing calls to a range of methods. Key methods include runReport for standard reporting, runPivotReport for multidimensional analysis, getMetadata for accessing information about available metrics and dimensions, runRealtimeReport for accessing real-time data, and runFunnelReport for funnel analysis. Each method plays a critical role in different aspects of data reporting and analysis.

Differences in Universal Analytics API and Google Analytics 4 API

Google Analytics API and GA4 API represent two different stages in the evolution of Google’s analytics platforms. The original Google Analytics API, linked with Universal Analytics, provides traditional website tracking and reporting export features, focusing on session-based data, and offers extensive compatibility with various web technologies.

On the other hand, GA4 API, associated with the GA4 Data API, adopts an event-based data model, which is more adaptable to both web and app environments.

The GA4 Data API streamlines data querying and enhances data access across platforms, making it a crucial upgrade for users transitioning from Universal Analytics. GA4 emphasizes user engagement and cross-platform tracking, offering more advanced machine learning insights. This shift reflects a broader industry trend towards comprehensive, user-centric analytics.

Universal Analytics offers several APIs, each with distinct functionalities:

Core Reporting API (v3): This API allows users to access most of the data from Google Analytics reports. It’s useful for creating custom reports and automations. This version (v3) is associated with Universal Analytics and offers robust, session-based data retrieval capabilities.
Unsampled Data API: This API provides access to unsampled data in Google Analytics. Normally, for large data sets, Google Analytics uses sampling to estimate data trends, which can sometimes compromise accuracy. The Unsampled Data API allows for the extraction of full data sets, ensuring more precise and reliable reporting, particularly beneficial for high-traffic websites.
Real-Time Reporting API: This API allows developers to access real-time data about what’s happening on their website or app. It can display active users, their geographic locations, the pages or events they are interacting with, and more. This is particularly useful for monitoring the immediate effects of marketing campaigns, website changes, or events.

After the recent transition to GA4, among the APIs mentioned - Core Reporting API (v3), Unsampled Data API, and Real Time Reporting API - none are directly compatible with Google Analytics 4 (GA4). These APIs are designed for use with Universal Analytics, the predecessor to GA4.

For GA4, Google has introduced new APIs, such as the Google Analytics Data API (v1), which is designed to work with the event-based data model and advanced features of GA4.

This Google Analytics API provides access to both standard and custom reports, reflecting the more flexible and user-centric approach of GA4. The GA4 Data API is essential for leveraging the full capabilities of GA4, ensuring seamless data access and enhanced querying across platforms.

If you’re transitioning to or already using GA4, you’ll need to use the APIs specifically designed for it, rather than the ones used for Universal Analytics.

What are GA4 API Quotas?

GA4 API quota limitations are an essential aspect of Google Analytics 4, designed to ensure fair and efficient use of resources among all free users. These quotas are categorized into three types: Core, Realtime, and Funnel

Each type of request — whether it's to Core or Real-time methods — draws from its respective quota. This separation means that one request won't consume quotas from both categories.

Two key quotas impacting Looker Studio reports are concurrent requests and hourly tokens:

Concurrent Requests: This quota is determined by the number of simultaneous viewers accessing reports. As more users view reports at the same time, the quota limit is reached more quickly.
Hourly Tokens: The complexity and frequency of interactions with the report affect this quota. Factors like the number of visualizations, the complexity of the data being consumed, and the use of filters contribute to the consumption of hourly tokens.

Understanding these quotas is crucial for users who rely on GA4 for detailed analytics and reporting, as exceeding these limits can restrict data access and require modifications in data request strategies. For more detailed information, the official Google Analytics data documentation offers an extensive list and explanation of these quotas.

Purpose of API Quotas in Google Analytics 4

Google Analytics 4 implements API quotas as a means to maintain equitable access for all users while safeguarding the system's performance.

The GA4 team highlights two key reasons for these quotas:

Resource Management

Google's infrastructure, despite being robust, operates with a finite number of servers. Unlimited user access could potentially deplete Google's computing power, adversely affecting service performance.

API quotas are therefore essential in ensuring that all developers have fair access to resources without overburdening the system.

Protection Against Abuse

The quotas in GA4 also serve as a protective measure against system abuse. Instances like a faulty program incessantly consuming tokens can monopolize Google's resources, impeding service availability for other users engaged in meaningful activities.

By enforcing quotas, Google can prevent such scenarios, ensuring its services remain accessible and reliable for all users.

Understanding the Limitations in Google Analytics 4 API

As with many digital marketers or website operators, you’re likely familiar with the frequent emails from Google Analytics. These aren’t just the usual monthly reports, but also reminders about the transition from Universal Analytics to Google Analytics 4 (GA4).

Introduced in October 2020, GA4 has been available for some time, allowing users the option to switch from the older Universal Analytics version. During this period, Looker Studio (formerly Google Data Studio) has been used to extract data and compile marketing reports.

Utilizing the Google Analytics API rather than the standard interface expanded the possibilities for gaining insights, enabling a deeper dive into hierarchical traffic analysis and time-specific attribution. It is crucial to enable the Google Analytics APIs to ensure proper access and functionality when using a service account to access Google Analytics data.

However, challenges emerged with the release of Google Analytics 4 API v1 in March 2022. While there has always been a quota for API usage per service account, Google began to enforce these limits more stringently from November 2022. This tightening of restrictions is likely the reason behind any API quota errors you encounter within your Looker Studio dashboards.

Errors in Google Analytics API 4

The top five errors encountered while using Google Analytics 4 (GA4) API, particularly in conjunction with Looker Studio, primarily relate to quota limits and data fetching issues:

Data Quota Limit Exceeded: This occurs when the data quota for a GA4 property is surpassed. GA4 has different quotas for its Standard and 360 versions, and exceeding these limits results in an inability to visualize data in Looker Studio until the quota resets.
Failure in Data Retrieval: When the property-level quota of GA4 is reached, all users associated with that property are affected. This means, if the quota is consumed by either Looker Studio reports or other data sources, Looker Studio may be unable to access new data.
API Request Quota Exceeded: This error indicates that the allowed number of API requests has been reached. GA4's API permits data retrieval in two date ranges per request, and reaching this limit impedes further data access.
Concurrent Request Quota Exhausted: This error arises when the number of simultaneous API requests exceeds the limit, which is typically 10 for non-paid GA properties. Exceeding this limit in Looker Studio, either through complex reports or multiple users making concurrent requests, triggers this error.
Generic Error Message: Sometimes, a generic error message appears due to authentication issues. While switching to an older authentication method like MD5 might resolve this, it's not generally recommended due to increased security vulnerabilities compared to more modern methods like scram-sha-256.
