Overview

The Clinical Data Exchange (CDex) API is a FHIR-based interoperability API that enables an unsolicited data-exchange flow, where a provider proactively sends relevant clinical data to payer systems without a prior explicit request, based on a known business or clinical need.

It enables the exchange of a wide range of clinical data formats, including FHIR resources and Bundles, C-CDA documents, PDFs, and other file types.

To enable efficient exchange of large clinical documents, the CDex API supports a PreSigned URL-based attachment workflow. Clients obtain a secure, time-limited PreSigned URL to upload documents and then reference the uploaded content during CDex submission. This approach improves performance, reduces payload size, and provides a secure and scalable mechanism for exchanging large clinical attachments.
