What is the new or undocumented data available in the Google Postmaster Tools API?

Summary

The Google Postmaster Tools API is evolving, with several reports of new, undocumented data. The `userReportedSpamRatioUpperBound` metric is a key example, though its meaning is debated. Users report discrepancies between the API data and the Postmaster Tools UI. New features may be rolled out in phases or be part of a beta program. Contextual interpretation is crucial, alongside comparing API data with internal logs and deliverability platforms. API access requires domain verification and sufficient traffic. Rate limits and authentication guidelines must be followed. Experts advise caution with undocumented features and note that Google TrafficStats resources does not explicitly state the metric.

Key findings

  • New Metric Observed: `userReportedSpamRatioUpperBound` is appearing, but documentation is lacking, and interpretation is uncertain.
  • Data Discrepancies: The API and UI data from Postmaster Tools show discrepancies which are undocumented.
  • Phased Rollouts: New features might be released gradually, not all users get immediate access.
  • Potential Beta Program: Some data may be part of a beta, thus lacking full public details.

Key considerations

  • Context Matters: Understand context around API data, considering volume, engagement, and authentication practices.
  • Cross-Reference: Correlate API data with internal logs, feedback loops, and deliverability monitoring to get a clearer picture.
  • Access Requirements: Meet the requirements for API access of domain verification and traffic levels
  • Adhere to Guidelines: Stick to API usage guidelines, particularly regarding rate limits and authentication.
  • Approach with Caution: Approach new and undocumented metrics with caution and validate results.

Several new and potentially undocumented data points have emerged in the Google Postmaster Tools API. Specifically, the `userReportedSpamRatioUpperBound` metric is being observed, although its precise meaning and reliability are debated. Some users are also reporting discrepancies between the data displayed in the Postmaster Tools UI and the API results. Access to new features may be rolled out in phases, and some data may be part of a beta program. Understanding the context of Postmaster Tools data, correlating it with other data sources, and monitoring for discrepancies are crucial. Authentication-related metrics and data from the Gmail political pilot program may also be factors.

Key opinions

  • New Metric: The `userReportedSpamRatioUpperBound` metric has appeared but is undocumented and its meaning is unclear.
  • Data Discrepancies: Discrepancies exist between the Postmaster Tools UI and the API data.
  • Phased Rollout: New features and data may be rolled out in phases, not available to all users immediately.
  • Beta Program: Some data might be part of a beta program, limiting public documentation and availability.

Key considerations
