Four Ways BigQuery Beats Direct API Sources in Looker Studio

by Lance Abbrederis on Feb 28, 2025

The simplicity of Google Looker Studio has enabled countless businesses to visualize their data without the need for a database or writing SQL code.

While direct API connections remain a popular way to pull data into reports, they come with limitations — especially as agencies and brands scale their analytics efforts.

If you've ever struggled with API limits, slow-loading dashboards, maintaining historical data, or simply managing the time it takes to make manual updates, it's time to consider adding a dedicated data warehouse like Google BigQuery to your analytics stack.

Advantages of Connecting Looker Studio to BigQuery Versus Using Native APIs

Transitioning from using direct API connections to BigQuery as your Looker Studio data source will unlock new capabilities that can help improve performance, scalability, and long-term data strategy.

Below are four advantages of using BigQuery instead of relying on native API connections.

1. Gemini-Powered AI Assistant Integration

With BigQuery as your data source, you can integrate Google's AI Assistant, Gemini, for AI-powered analysis via chat functionality. The Gemini/Looker Studio Pro integration enables instant data analysis through conversational queries.

Using this Gemini integration, you can query your data with Conversational Analytics, enabling you to chat with your data directly in Looker.

To access Gemini in Looker, you will need a Looker Studio Pro subscription and your data needs to be stored in Google BigQuery

2. Data Ownership and Scalability

Many applications limit the amount of historical data that can be retrieved through their APIs. Google Campaign Manager, for example, only allows you to export Floodlight report data for 60 days and Standard Report data is limited to two years.

By loading data into BigQuery daily, you can maintain a record of your historic data past the limit of what the API is allowed to return.

3. Reporting Flexibility and Long-Term Viability

Managing multiple Looker Studio reports with direct API connections can become a time-consuming, manual task. Updating a direct query data source across ~25 Looker Studio reports isn't generally a big project, but as you continue to scale and reach hundreds of reports, the amount of effort compounds if there isn't a good way to make the same update globally.

By consolidating your data into a centralized BigQuery table, you maintain consistent taxonomies and schemas across all reports. This simplifies updates, reduces inconsistencies, and ensures long-term scalability.

4. Business Intelligence Beyond Performance Reports

Many agencies use live API connections to deliver performance metrics to clients, and while this solves the customer requirement, it doesn't provide a solution for other data uses like campaign monitoring, billing, budget pacing, case studies, and market insights.

While direct API connections seem like a quick and easy way to pull data into Looker Studio, they come with limitations that can slow you down as your reporting needs change.

BigQuery offers a more scalable, flexible, and future-proof solution for storing and managing your data, giving you complete control, enabling AI-driven insights, and ensuring your reports remain reliable over time.

Using Launchpad to Load Data into BigQuery
