Question

What could be causing issues when trying to fetch data from Custom Analytics Views in the Azure DevOps API, and how can I resolve them?
When querying Custom Analytics Views in the Azure DevOps API, I am encountering errors such as missing data, authentication failures, or performance issues. What are the potential reasons behind these problems? How can I verify API permissions, optimize query parameters, or handle large datasets effectively? Are there specific best practices for working with Custom Analytics Views to ensure consistent and reliable data retrieval?

Answer 1

When querying Custom Analytics Views in Azure DevOps API, issues like missing data, authentication failures, or performance bottlenecks often occur due to:

1. API Permissions & Authentication Issues – Ensure PAT has "Analytics Read" permissions and test authentication using Postman or PowerShell.
2. Query Constraints & Filtering – Use $top, $skip, and $select parameters to control pagination and select necessary fields.
3. Handling Large Datasets – Avoid row limits by batch processing, using Power BI incremental refresh, or applying server-side filtering ($filter=State eq 'Active').

Best Practices

Use latest API versions for performance improvements.
Implement indexing, caching, and retries for stability.
Log responses and handle timeouts efficiently.
