Please describe your experience learning or using healthcare APIs (such as FHIR, C-CDA, or proprietary vendor APIs like those from Epic or Cerner). In your answer, please touch on: 1. Which specific APIs have you worked with? 2. The context of your work (e.g., what problem you were solving or what you built). 3. If you're new to them, describe how you would approach learning a new healthcare API from scratch.✱
