Introduction to Cambio Open Services: COS

What is the COS platform?

Cambio Open Services allow third-party applications to access our open APIs in COSMIC. These APIs are meant to be used in a business to business (B2B) context.

Test in the COS sandbox

Our COS sandbox environment allows you to test your application using synthetic test data. The sandbox environment contains a complete installation of COSMIC with the available APIs in COS.

Two types of APIs in COS

The services in COS are of two different types:

  • FHIR profiles


Most APIs in COS are based on the FHIR platform specification. We have developed FHIR profiles that are adapted specifically to COSMIC.

Some APIs in COS are still REST APIs, but our long-term goal is to replace them with FHIR APIs.
