WSO2 Machine Learner 1.1.0 includes revisions made to the REST API since the Machine Learner 1.0.0 release. These modifications include introducing new query parameters, changing path parameters, introducing new APIs etc. However, you can use the previous REST API version if required by making slight modifications to the URI.
In ML 1.1.0, a user can invoke an API by providing the URI in the following three ways.
| Method | Example | Outcome |
|---|---|---|
| Without specifying the version. | https://localhost:9443/api/configs/algorithms | The latest API version (i.e. V11) is invoked. |
Specifying V10 as the version | https://localhost:9443/api/v10/configs/algorithms | The V10 API version is invoked. |
Specifying V11 as the version | https://localhost:9443/api/v11/configs/algorithms | The V11 API version is invoked. |
The following are the REST APIs that are implemented in WSO2 Machine Learner.
