Andy enhanced the tryVital/docs repository by improving API documentation related to external ID handling and patient name validation. Focusing on Markdown and documentation best practices, Andy standardized data formats and validation rules, clarifying how external IDs should be formatted for PSC appointment bookings and detailing regex-based patient name validation across multiple endpoints. These updates included comprehensive examples and quickstart references, directly addressing integration pain points and reducing onboarding friction for developers. While no code-level bugs were addressed, the work demonstrated depth in technical writing and API design, resulting in clearer, more maintainable documentation that supports faster, more reliable API integrations.
