OSCAR Pro integration: the web services, explained
How third-party systems connect to OSCAR Pro and the OSCAR family: the REST and SOAP web services, how access is granted, and what hosting must enable.

The short version
- OSCAR began as an open-source EMR at McMaster University. OSCAR Pro is the commercial edition from WELL Health; other distributions exist.
- The OSCAR family exposes web services: a REST layer for most records and SOAP services for some, including lab uploads.
- REST clients are registered by the clinic's OSCAR administrator and authorized by a user.
- Which services are enabled depends on the edition, version and hosting provider, so confirm before you plan.
- Clinic Conductor is live in production with OSCAR Pro.
The OSCAR family
OSCAR EMR started as an open-source project at McMaster University and became one of the most widely used EMRs in Canadian primary care. Several editions have grown from it. OSCAR Pro is the commercial edition supported by WELL Health; other distributions are maintained by other groups. They share a common foundation, which is why integration patterns are similar across them, and they differ in version and configuration, which is why the details have to be confirmed clinic by clinic.
The web services
OSCAR exposes its records through web services served from the EMR itself. Two families matter for integration.
OSCAR web services at a glance
| Detail | REST services | SOAP services |
|---|---|---|
| Typical records | Patient demographics, schedule, prescriptions, documents, labs, ticklers, forms | Demographics, scheduling and booking, allergies, preventions, measurements, prescriptions, documents, lab upload |
| Access | OAuth client registered by the clinic's administrator, then authorized by a user | Service credentials issued by the EMR |
| Best suited to | Modern integrations reading and writing specific records | Established interfaces, and lab results where only SOAP is offered |
OSCAR also supports eForms, which many clinics use for intake and questionnaires, and receives lab results and hospital reports through the provincial feeds where the clinic is set up for them.
How access is granted
For REST integrations, the clinic's OSCAR administrator registers the integration as a client in OSCAR's REST client management screen, which issues its credentials. A user at the clinic then authorizes the connection. On hosted editions, including most OSCAR Pro clinics, the hosting provider usually has to enable the web services first. Plan for that step: it is the most common reason an OSCAR integration waits.
What to ask an OSCAR integration partner
- Is your integration live with my edition and version of OSCAR today?
- Which services do you need enabled, and have you worked with my hosting provider before?
- Do you write back into the chart, and where do the records appear?
- How are documents labelled and routed to the right provider's inbox?
- How do you handle a failed write or a service that is temporarily unavailable?
OSCAR and the rest of the clinic
OSCAR clinics often already run add-ons for online booking, forms or messaging. An orchestration layer complements them: it connects to OSCAR once and conducts the work between OSCAR, the phone line, the fax line, intake and assessment data, with one set of rules and one audit trail. See our EMR integration guide for the broader picture.
Questions, answered
Does OSCAR Pro have an API?
Yes. The OSCAR family exposes REST and SOAP web services. REST clients are registered by the clinic's administrator and authorized by a user. On hosted editions, the hosting provider usually has to enable the services.
Is OSCAR Pro the same as OSCAR EMR?
OSCAR Pro is a commercial edition of OSCAR, supported by WELL Health. It shares its foundation with other OSCAR distributions, which differ in version and configuration.
Is Clinic Conductor integrated with OSCAR Pro?
Yes. Clinic Conductor is live in production with OSCAR Pro.
