Update Skillset (Azure AI Search REST API)

  • Article

You can update an existing skillset and knowledge store using an HTTP PUT, specifying the name of the skillset to update on the request URI.

PUT https://[servicename].search.windows.net/skillsets/[skillset name]?api-version=[api-version]
  Content-Type: application/json
  api-key: [admin key]

Note

Skillsets are the basis of AI enrichment in Azure AI Search. A free resource is available for limited processing, but for larger and more frequent workloads, a billable Cognitive Services resource is required. For more information, see Attach a Cognitive Services resource to an Azure AI Search skillset.

URI Parameters

Parameter Description
service name Required. Set this to the unique, user-defined name of your search service.
skillset name Required. The request URI specifies the name of the skillset to update.
api-version Required. The current stable version is api-version=2020-06-30. See API versions for more versions.
disableCacheReprocessingChangeDetection Optional. Used for incremental enrichment (false by default). Set to true to prevent updates to existing documents based on the current action. For more information, see cache management.

Request Headers

The following table describes the required and optional request headers.

Fields Description
Content-Type Required. Set this to application/json
api-key Optional if you're using Azure roles and a bearer token is provided on the request, otherwise a key is required. An api-key is a unique, system-generated string that authenticates the request to your search service. Update requests must include an api-key header set to your admin key (as opposed to a query key). See Connect to Azure AI Search using key authentication for details.

Request Body

The request body syntax is the same as for Create Skillset.

When updating an existing skillset, the entire definition is replaced with the contents of the request body. In general, the best pattern to use for updates is to retrieve the skillset definition with a GET, modify it, and then update it with PUT.

Response

For a successful request, you should see status code "201 Created".

By default, the response body will contain the JSON for the skillset definition that was created. However, if the Prefer request header is set to return=minimal, the response body will be empty, and the success status code will be "204 No Content" instead of "201 Created". This is true regardless of whether PUT or POST is used to create the skillset.

Examples

Example: Update a skillset

The following example updates a skillset used for enriching a collection of financial documents.

PUT https://[servicename].search.windows.net/skillsets/financedocenricher?api-version=2020-06-30
api-key: [admin key]
Content-Type: application/json

The body of request is a JSON document. This particular skillset uses two skills asynchronously, independently processing the substance of /document/content as two different transformations. Alternatively, you can direct the output of one transformation to be the input of another. For more information, see How to define a skillset.
