The Custom Web API skill allows you to extend AI enrichment by calling out to a Web API endpoint providing custom operations.
Similar to built-in skills, a Custom Web API skill has inputs and outputs. Depending on the inputs, your Web API receives a JSON payload when the indexer runs, and outputs a JSON payload as a response, along with a success status code.
The response is expected to have the outputs specified by your custom skill. Any other response is considered an error and no enrichments are performed.
