The ONTAPI calls are organized in categories. When selecting a specific category from the sidebar, all the ONTAPI calls with their associated REST equivalents are presented on the page.

You can search this mapping documentation using the search bar available at the top of the page. If you are interested in a specific ONTAPI call or parameter, you should enclose the search term in double quotes (for example, "ems-autosupport-log"). Alternatively, you can download a PDF version of the entire mapping document and search the PDF locally. Click Available PDFs at the top left to download the PDF.

After determining the REST API call that replaces an ONTAPI call, you’ll need to review the details of the REST call at the ONTAP online documentation page. See ONTAP API reference for more information.

Every ONTAPI call with a REST equivalent includes a usage field indicating whether the call can or cannot be used against a Storage VM (SVM) management LIF. If a specific call can be used against an SVM LIF and you are transitioning the call from an SVM management LIF to a cluster management LIF, make sure to specify the SVM name or UUID using the SVM-related properties of the REST endpoint.

In some cases there is no corresponding REST call available for an ONTAPI call. If there is no direct REST equivalent but there is a CLI equivalent, you can use the REST CLI passthrough feature to access it.

NetApp is committed to supporting the modernization of your ONTAP applications as you transition from ONTAPI to REST. If you find any ONTAPI calls or parameters required by your automation processes that are not currently supported by the ONTAP REST API, please let us know!
