As you know, last June we launched the API 5 — a version with completely new architecture, which allows to add almost any new functionality with backward compatibility support. During all that time the fifth version has been working as an add-on to the API Live 4; however, all the new features are supported only in API 5.

Now we’d like to announce our plans of the gradual transition to the API version 5 and discontinuation of the API 4 and API Live 4 methods — so you can prepare for forthcoming changes right now.

These changes consist of a couple of steps:

I. In three months — approximately at the end of June — we plan to deprecate several methods of API 4 and API Live 4 versions. Please see the list of these methods below.

II. After a month after the completion of the first step, these methods will no longer be available.

We will limit our support for other deprecated methods in API 4 and Live 4 as respective API 5 services are introduced.

You will be kept informed about each step.

The list of deprecated methods:

• Campaigns managing:
  CreateOrUpdateCampaign (Live) and CreateOrUpdateCampaign, GetCampaignsList (Live) and GetCampaignsList, GetCampaignsListFilter (Live) and GetCampaignsListFilter, GetCampaignsParams (Live) and GetCampaignsParams, GetCampaignParams (Live) and GetCampaignParams, DeleteCampaign, ResumeCampaign, StopCampaign, ArchiveCampaign, UnArchiveCampaign
