Greptile Summary

This PR adds support for provider_query_params to the SSO getAuthorizationUrl method, bringing it in line with similar functionality already present in the UserManagement module. The changes involve three key modifications:

Interface Enhancement: A new optional providerQueryParams property is added to the SSOAuthorizationURLOptions interface, typed as Record<string, string | boolean | number> to support common query parameter data types.

Implementation Refactor: The SSO class undergoes a significant change in query string serialization. The existing toQueryString function is completely rewritten to use the qs library instead of the native URLSearchParams API. This enables handling of complex objects and arrays while maintaining backward compatibility through specific configuration options (alphabetical key sorting, RFC1738 format for space encoding as +).

Comprehensive Testing: New test cases verify the functionality works correctly with populated provider query params containing mixed data types (string, number, boolean) and handles empty objects gracefully. The tests use inline snapshots to verify exact URL encoding behavior.

The implementation follows the established pattern from the UserManagement module, using qs.stringify with consistent configuration options. The change also simplifies provider_scopes handling by removing manual array joining, as the qs library handles array serialization natively with the 'repeat' format. This maintains backward compatibility while extending functionality to support structured query parameters for identity providers during SSO authorization flows.

Confidence score: 4/5

• This PR introduces significant query string serialization changes that could affect existing integrations, though backward compatibility measures are in place
• Score reflects the major refactoring of core URL generation logic combined with comprehensive testing and careful compatibility considerations
• Pay close attention to the SSO implementation file and verify the qs library configuration maintains exact backward compatibility
