What can you build with IAM Service Account Credentials API?

IAM Service Account Credentials API is a Analytics API. Developers commonly use analytics APIs for:

  • tracking product usage and user behaviour
  • building custom reporting and BI dashboards
  • measuring marketing and campaign performance
  • running funnel, retention, and cohort analysis
  • aggregating metrics from multiple data sources

No authentication required. This API is open — no signup or key needed. Ideal for quick prototypes and public-facing features. IAM Service Account Credentials API is free to use, making it a low-risk choice to experiment with.
