OpenSpecimen v2.0 exposes REST APIs that can be consumed to developed custom interfaces and and for integration with other databases. The REST APIs will be consumed by the OpenSpecimen v2.0 User Interface.
Common Characteristics of REST Resources
The following characteristics apply to all OpenSpecimen API resources:
- You access a resource by sending an HTTP request to the OpenSpecimen server. The server replies with a response that either contains the data you requested or a status indicator, and in some cases both.
- All resources are located at
http[s]://<host-name>:<port>/catissuecore/rest. - You request a particular resource by appending a particular path to this base URL
- All resources may return any of the below mentioned status codes:
| code | Applies to | Status Message |
|---|---|---|
| 200 | All resources | |
| 201 | All POST/PUT requests | Resource created/updated successfully |
| 400 | All requests | Invalid parameters, this will also includes application specific error messages |
| 401 | All requests | Authorization failed |
| 403 | All requests | |
| 404 | All requests | Resource not found, also includes specified resource id/name/title |
