Cloud Healthcare HL7v2 API
The Cloud Healthcare HL7v2 API provides managed ingestion, storage, and retrieval of HL7 version 2.x messages, which are the most widely used standard for exchanging clinical data between hospital information systems. It supports message parsing, filtering, and routing via Pub/Sub notifications. The API enables integration with legacy EHR and hospital systems by accepting raw HL7v2 messages and making them queryable through a RESTful interface. Messages can be exported to Cloud Storage or BigQuery for downstream analytics. Individual messages are limited to 10 MB (base64-encoded data field).
