OSCAR REST Web Services API is published by [OSCAR EMR](https://apis.io/providers/oscar-emr/) on the [APIs.io](https://apis.io/) network. Tagged areas include EHR, EMR, REST, Primary Care, and Canada. The published artifact set on APIs.io includes API documentation, an API reference, a getting-started guide, and authentication docs.

OSCAR's REST web-services layer, served under the /ws/services base path of a deployed OSCAR instance, covering most of the clinical record - scheduling/appointments, demographics, billing, prescriptions, documents, labs, ticklers, eForms and providers. Applications register as REST clients through the OSCAR Administration interface and authenticate provider users with 3-legged OAuth 1.0a (/ws/oauth/initiate, /ws/oauth/authorize, /ws/oauth/token). As self-hosted software the host and web context are deployment-specific (documented example: http://localhost:8080/oscar_15/ws/services), so no single public base URL exists. The API is documented on the OSCAR EMR developer wiki; runtime documentation is generated with RAML (RAML for JAX-RS) rather than OpenAPI/Swagger, and there is no downloadable static spec published.
