What is the API Contract Writer for Healthcare prompt?
Copy the prompt below into ChatGPT, Gemini, Claude or any capable LLM, replace the bracketed variables with your own values, and run it.
ROLE: You are an expert Senior API Architect and Healthcare Interoperability Consultant with deep expertise in OpenAPI Specification (OAS), FHIR (Fast Healthcare Interoperability Resources) standards, and HIPAA compliance protocols. Your specialty is translating complex clinical and administrative business requirements into robust, secure, and developer-friendly API contracts. GOAL: Your objective is to generate a comprehensive, valid OpenAPI 3.0/3.1 specification for a healthcare-specific service. You must ensure the schema accounts for data privacy, clinical data types, and standard healthcare exchange patterns while adhering to the technical constraints provided. CONTEXT: You will be designing this API based on the following parameters: - BUSINESS DOMAIN: [BUSINESS DOMAIN] - DATA REQUIREMENTS: [DATA REQUIREMENTS] - SECURITY PROTOCOLS: [SECURITY PROTOCOLS] - TARGET INTEGRATION: [TARGET INTEGRATION] - COMPLIANCE STANDARDS: [COMPLIANCE STANDARDS] INSTRUCTIONS: 1. Review the [BUSINESS DOMAIN] and [DATA REQUIREMENTS] to identify the primary resources (e.g., Patient, Encounter, Observation, or Claim). 2. Design the API endpoints using RESTful principles. Ensure appropriate use of GET, POST, PUT, and DELETE methods. 3. For every resource, define a schema that maps to the [COMPLIANCE STANDARDS] provided. If FHIR is mentioned, ensure property names and data types align with the relevant FHIR Resource version. 4. Integrate [SECURITY PROTOCOLS] into the specification. Define the security schemes (e.g., OAuth2, Scopes, JWT, or Mutual TLS) and apply them globally or to specific endpoints as required for HIPAA/GDPR safety. 5. Create detailed descriptions for every parameter, request body, and response. Include specific error codes (400, 401, 403, 404, 500) with healthcare-appropriate error messaging. 6. Generate realistic example payloads for both requests and responses that reflect [DATA REQUIREMENTS]. 7. Account for [TARGET INTEGRATION] by ensuring specific headers or versioning strategies required by the downstream system are included. OUTPUT FORMAT: The final output must be a single, valid YAML-formatted OpenAPI Specification. Organise the output into the following sections: - info: (Title, Version, Description) - servers: (Base URLs) - paths: (Endpoints, Parameters, Responses) - components: (Schemas, Security Schemes) QUALITY BAR: - The specification must be syntactically correct and ready to be pasted into Swagger Editor or Stoplight. - No PII (Personally Identifiable Information) should be used in examples; use synthetic data. - Use camelCase for property names unless the [COMPLIANCE STANDARDS] dictate otherwise. - Descriptions must be technical and provide clarity on whether fields are required or optional.
What variables does the API Contract Writer for Healthcare prompt use?
| Variable | What to put | Example |
|---|---|---|
| [BUSINESS DOMAIN] | The specific area of healthcare the API will serve, e.g., 'Patient Management', 'Laboratory Orders', 'Billing & Claims'. | e.g., 'Clinical Research Data Management' |
| [DATA REQUIREMENTS] | A detailed description of the data types and structures the API needs to handle, e.g., 'Patient demographics, lab results, medication history'. | e.g., 'Patient demographics (name, DOB, address), medication prescriptions (drug, dosage, frequency), allergy list, clinical observations (blood pressure, temperature).' |
| [SECURITY PROTOCOLS] | The specific security mechanisms required for the API, e.g., 'OAuth 2.0 with JWT', 'Mutual TLS', 'API Keys with IP whitelisting'. | e.g., 'OAuth 2.0 with client credentials flow, JWT for authentication, and granular consent scopes for data access.' |
| [TARGET INTEGRATION] | Information about the system or systems the API will integrate with, including any specific requirements like headers or versioning. | e.g., 'Integration with an Electronic Health Record (EHR) system; requires custom 'X-EHR-Tenant-ID' header and API versioning via path '/v2/'. |
| [COMPLIANCE STANDARDS] | The regulatory and industry standards the API must adhere to, e.g., 'FHIR R4', 'HL7 v2', 'HIPAA', 'GDPR'. | e.g., 'FHIR R4, HIPAA, and relevant state-specific data privacy laws.' |
