API Life cycle summary and definition

This list defines the support offered by Relativity as the APIs transition through different phases of the deprecation life cycle.

Life cycle support

The following terms refer to the different phases of the API deprecation life cycle:

  • General Availability: In the General Availability (GA) phase, the API is released and available for use.
  • Deprecated: In the deprecated phase, we no longer recommend using the API. While deprecated classes and methods are still available, they are tagged obsolete because they will be removed in future releases. You shouldn't use them when implementing new code. Additionally, begin upgrading any existing code, so that it no longer references these obsolete classes and methods.
  • Removed: In the removed phase, Relativity no longer exposes the API. Any functionality using the removed API will break.

Removal process

All RSAPI APIs have been removed in RelativityOne. For Relativity Server customers, we will provide a specific window for deprecation once we announce our next Server release date. We will be updating this part of the page with more details on timing for this process as they are finalized.

API migration matrix

The following table contains legacy features that have been removed, and links to newer APIs that support similar functionality. The replacement APIs allow code compatibility between Relativity Server and RelativityOne.

**** API/Service is released, and the documentation will be available soon.

Identifying RSAPI usage

Your code may be relying on RSAPI, even if you are calling Relativity REST services. To determine whether your code is still using RSAPI, you can search for IRSAPIClient in your code if you are calling Relativity .NET APIs, or search for Relativity.REST/Relativity or Relativity.REST/Workspace routes/paths in your code if you are calling Relativity REST endpoints.
