Library Application (REST)

Through the REST API, the Library Application API allows clients to read application metadata and RAP files from the library, upload new applications, and update or delete existing applications.

Guidelines for the Library Application 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 the {versionNumber} placeholder to the version of the REST API that you want to use, using the format lowercase v and the version number, for example v1.
Set other path parameters in the URLs to the Artifact ID of a given entity, for example setting {workspaceID} to the Artifact ID of a workspace.

To indicate the admin-level context, set the {workspaceID} path parameter to -1.

For example, you can use the following URL to retrieve an application:

Copy

1
<host>/relativity.rest/api/relativity-environment/{versionNumber}/workspace/-1/libraryapplications/{artifactID}

Set the path parameters as follows:

{versionNumber} to the version of the API, such as v1.
{artifactID} to the Artifact ID of a specific application.

Client code sample

To use the Library Application service, send requests by making calls with the required HTTP methods. See the following base URL for this service:

Copy

1
<host>/Relativity.REST/API/relativity-environment/{versionNumber}/workspace/-1/libraryapplications/

For the workspace identifier in the URL, use -1 to indicate the admin-level context. This value is required for all URLs in the Library Application service. For additional guidelines, see Library Application API.

public async Task<LibraryApplicationResponse> ReadLibraryApplication(int applicationID)
{
    LibraryApplicationResponse response = null;
    using (HttpClient client = new HttpClient())
    {
        client.DefaultRequestHeaders.Add("X-CSRF-Header", string.Empty);
        client.DefaultRequestHeaders.Add("Authorization", "Basic " + Convert.ToBase64String(Encoding.GetEncoding("ISO-8859-1").GetBytes("test.com:SomePassword!")));
        client.DefaultRequestHeaders.Add("X-Kepler-Version", "2.0");
        client.BaseAddress = new Uri("https://localhost/");

        string url = $"/Relativity.REST/API/relativity-environment/v1/workspace/-1/libraryapplications/{applicationID}/";
        System.Net.Http.HttpResponseMessage httpResponse = await client.GetAsync(url);
        httpResponse.EnsureSuccessStatusCode();
        string content = await httpResponse.Content.ReadAsStringAsync();
        response = JsonConvert.DeserializeObject<LibraryApplicationResponse>(content);
    }

    return response;
}

Create a library application

To create a library application, send a POST request using multi-part form data. The first part should contain the request as JSON content type application/json. The second part should contain the file as binary with content type application/octet-stream:

Copy

1
2
<host>/relativity.rest/api/relativity-environment/{versionNumber}/workspaces/-1/libraryapplications
<host>/relativity.rest/api/relativity-environment/{versionNumber}/workspaces/-1/libraryapplications/{packageGuid}

The alternative version takes a GUID referring to a previously uploaded package, see UploadPackage. The body is empty.

The body of the request is empty.

The response contains the following fields for the library application:

ApplicationIdentifier - the identifier of the application.
- ArtifactID - the Artifact ID of the library application.
- Guids - an array of GUIDs used to identify the library application.
Actions - an array of Action objects indicating operations that you have permissions to perform on this library application. For example, you may not have permissions to modify a library application due to your privileges. Each Action object contains the following fields that are available as extended metadata:
- Name - name of an operation available through REST for the library application, such as delete, update, and so on.
- Href - the URL used to make an HTTP request for the operation.
- Verb - the name of the HTTP method for the operation.
- IsAvailable - a Boolean value indicating whether the operation is available or not on this library application.
- Reason - provides an explanation for the unavailability of an action.
ApplicationInstallID - the ID of the application installation.
InstallStatus - the status of the application installation.
- Code - the status code indicating the state of the application installation.
- Message - a string that returns an informative message about the status of the request.

Retrieve a library application as a RAP file

To retrieve a library application as a RAP file, send a GET request for one of the following URLs:

Copy

1
2
<host>/relativity.rest/api/relativity-environment/{versionNumber}/workspace/-1/libraryapplications/{artifactID}/contents
<host>/relativity.rest/api/relativity-environment/{versionNumber}/workspace/-1/libraryapplications/{applicationGuid}/contents

The body of the request is empty.

The response will not be human-readable.

Update a library application

To update an application, send a PUT request using multi-part form data. The first part should contain the request as JSON content type application/json. The second part should contain the file as binary with content type application/octet-stream:

Copy

1
2
<host>/relativity.rest/api/relativity-environment/{versionNumber}/workspace/-1/libraryapplications
<host>/relativity.rest/api/relativity-environment/{versionNumber}/workspace/-1/libraryapplications/{packageGUID}

The alternative version takes a GUID referring to a previously uploaded package, see UploadPackage. The body is empty.

The request includes the following fields:

IgnoreVersion - indicates whether or not the version should be validated before updating the library application. By default only upgrades with a higher application version are allowed.
RefreshCustomPages - when set to true, the custom pages will be deployed immediately instead of as a task during the application install.
FileName - RAP file name of the library application.

Upload a RAP or XML file

This endpoint uploads a RAP or XML file to a temporary location in Relativity and returns a unique file identifier along with the meta data for the application. If the file is not in a valid format, a validation exception is thrown. This endpoint is used in conjunction with CreateAsync and UpdateAsync to implement workflows where the application's details need to be displayed for final confirmation before installing the application. To create an application, send a POST request using multi-part form data. The first part should contain the request as JSON content type application/json. The second part should contain the file as binary with content type application/octet-stream:

Copy
