orcidtr 0.1.0

Breaking Changes (December 28, 2025)

Authentication Behavior

• IMPORTANT: The package no longer automatically uses the ORCID_TOKEN environment variable for API requests
• Reason: The ORCID public API does NOT require authentication and actually rejects invalid tokens with 401 errors
• Impact: If you previously set ORCID_TOKEN and experienced authentication errors, you can now safely unset it
• Migration: If you need authentication (for rate limits or private data), pass the token explicitly: orcid_works(id, token = "your-token")
• Authentication is now truly optional as intended by ORCID’s public API design

Bug Fixes (December 28, 2025)

API Status Check

• Fixed orcid_ping() to use application/json instead of text/plain Accept header
• Now properly parses JSON response and returns “OK” when API is healthy
• Resolves 406 (Not Acceptable) errors from the status endpoint

Search Results

• Fixed empty search results returning 1 row of NA values instead of 0 rows
• orcid_search() and orcid() now correctly return empty data.table with 0 rows when no matches found
• attr(result, "found") still correctly shows 0 for total matches

Parser Improvements

• Enhanced parse_search_results() to handle NA values from safe_extract() when JSON contains null
• Prevents creation of placeholder rows with NA values

Documentation Improvements (December 28, 2025)

Clarified Authentication

• Updated README and vignette to explicitly state authentication is optional
• Explained when tokens are actually needed (rate limits, private data access)
• Provided OAuth2 flow example for users who do need tokens
• Corrected misconceptions from rorcid documentation about token requirements

Internal Documentation

• Updated orcid_request() documentation to reflect optional authentication
• Clarified that public API works without any token
• Improved error messages for authentication failures

Test Suite (December 28, 2025)

• Removed ORCID_TOKEN checks from all test helper functions
• All 302 tests now pass without requiring any authentication
• Tests correctly handle both authenticated and unauthenticated scenarios
