The Structured Analytics Job Manager service is an HTTP service, which you can use to automate operations on structured analytics sets through Representational State Transfer (REST). You can use the endpoints on this service to run an analysis of a structured analytics set, check the status of the analysis, retrieve document and other errors, and perform additional tasks. For general information about REST, see the REST API.
You can implement custom workflows for programmatically running structured analytic sets using the REST endpoints. For example, you can automate an analysis of a structured analytics set after performing only minor setup tasks in the Relativity UI. You could also implement a custom page that uses these endpoints to display the status of an analysis or errors that may have occurred.
You can find the REST Service reference documentation and download the OAS specification file in this topic. You can also use the Structured Analytics Job Manager service API through .NET. The API supports the use of progress indicators and cancellation tokens in .NET. For more information, see Structured Analytics Job Manager (.NET).
Note: You must install the Analytics application in your Relativity environment to automate workflows with the Structured Analytics Job Manager service. For more information, see
Guidelines for the Structured Analytics Job Manager service
Review the following guidelines for working with this service.
URLs
The URLs for REST endpoints contain path parameters that you need to set before making a call:
- Set {versionNumber} to the version of the API, using the format lowercase v and the version number, such as v1.
- Set other path parameters in the URLs to the Artifact ID of a given entity, such as {workspaceID} to the Artifact ID of a workspace.
For example, you can use the following URL to retrieve valid operations for a structured analytics set:
<host>/relativity.rest/api/relativity-structured-analytics/{versionNumber}/workspaces/{workspaceId}/sets/{sasArtifactId}/jobs/valid-tasks?Set the path parameters as follows:
- {versionNumber} to the version of the API, such as v1.
- {workspaceId} - the Artifact ID of the workspace that contains the structured analytics set.
- {sasArtifactId} - the Artifact ID of the structured analytics set.
Custom code
When implementing your custom code, follow these guidelines:
- Execute only valid operations for the state of a structured analytics set - Only certain operations are valid for the current state of your structured analytics set. See the following examples:
- A call to the CancelAsync endpoint is only valid when an analysis is currently running.
- A call to the RetryErrorsAsync endpoint is only valid when a structured analytics set is in an errored state.
To get a list of valid operations, make a call with the GetValidTasksAsync() endpoint. The ValidTaskResult object returned from this call contains a valid list of operations. If you attempt to execute an invalid operation, you receive 400 status response.
- Monitor the analysis progress - After making a successful call to the RunAsync endpoint, make calls to the GetStatusAsync endpoint to monitor the progress of your analysis.
- Use structured analytics set RDOs - The Structured Analytics Job Manager service doesn't expose standard CRUD operations for structured analytics set RDOs. Use the Object Manager service to create RDOs. For more information, see Object Manager (.NET) or Object Manager (REST).
Postman sample file
You can use the Postman sample file to become familiar with making calls to endpoints on the Error Manager service. To download the sample file, click Structured Analytics Postman file.

{
string url = "http://localhost/relativity.rest/api/relativity-structured-analytics/ + "v1/workspaces/" + workspaceId + "/sets/" + sasArtifactId + "/jobs";
var HttpWebRequest request = HttpWebRequest.CreateHttp(url)
request.Method = "POST";
request.ContentType = "application/json";
request.KeepAlive = false;
request.Headers.Add("Authorization", GetBase64AuthHeader());
request.Headers.Add("X-CSRF-Header", "-");

{
AnalyzeAll = analyzeAllDocs,
PopulateAll = repopulateAllDocuments
}
});
using (var requestContent = new System.IO.StreamWriter(request.GetRequestStream()))
{
//write request payload to stream
requestContent.Write(requestPayload);
requestContent.Flush();
}
var response = request.GetResponse();
string responsePayload = null;
using (var streamReader = new System.IO.StreamReader(response.GetResponseStream()))
{
responsePayload = streamReader.ReadToEnd();
}
JObject results = JObject.Parse(responsePayload);
if (results.Value<bool>("IsSuccess") == true)
{
System.Diagnostics.Debug.WriteLine($"Call to Run on SAS {sasArtifactId} on workspace {workspaceId} succeeded");
}
else
{
throw new Exception($"Call to Run on SAS {sasArtifactId} on workspace {workspaceId} failed. Error message: {results.Value<string>("Message")}");
}
}Generate result fields before running an analysis
You can optionally call the RunAnalysisPreparationAsync endpoint when you want to generate fields for storing results before you run an analysis on a new structured analytics set. For example, you might use the following workflow in this case:
- Create a new structured analytics set.
- Call the RunAnalysisPreparationAsync endpoint to generate fields used to store results from an analysis.
- Use the fields generated by the RunAnalysisPreparationAsync endpoint to create views and saved searches. You can also use this process to add a structured analytics set to a template workspace.
- Call the RunAsync endpoint to complete the analysis of the structured analytics set, and store results in the fields that you generated.
Send a POST request with a URL in the following format:
<host>/relativity.rest/api/relativity-structured-analytics/{versionNumber}/workspaces/{workspaceId}/sets/{sasArtifactId}/jobs/prepThe response contains the following fields:

]Work with legacy document fields
As of Relativity 9.5.196, structured analytics stopped writing results for email threading and textual near duplicate identification to Document fields. Instead, it writes results to fields on the Structured Analytics Results object. However, you can copy these results to the legacy document result fields by calling the RunCopyToLegacyAsync endpoint. It copies the results from the newly created fields to the legacy document fields from pre 9.5.196 versions of Relativity. For more information, see
Copy results to legacy document fields
Use the RunCopyToLegacyAsync endpoint to copy the results of an analysis to existing document fields.
Send a POST request with a URL in the following format:
<host>/relativity.rest/api/relativity-structured-analytics/{versionNumber}/workspaces/{workspaceId}/sets/{sasArtifactId}/jobs/copy-to-legacyThe response contains the following fields:
- IsSuccess - a Boolean value indicating whether the request succeeded or failed.
- Message - a string that returns an informative message about the status of the request.
