Advertising - Overview

Warning

Deprecation Notice: The Marketing Version 202503 (Marketing March 2025) has been sunset. We recommend that you migrate to the latest versioned APIs to avoid disruptions. For information on all the supported versions, refer to the migrations documentation. If you haven’t yet migrated and have questions, submit a request on the LinkedIn Developer Support Portal.

The Advertising API enables developers to manage LinkedIn's campaign management platform on behalf of clients through APIs. These APIs provide all features available in LinkedIn Campaign Manager, including creation and management of ad accounts, campaign groups, campaigns, creatives, ad types, and analytics.

With access to the Advertising API program, developers can create and manage Ad Accounts entirely through APIs without depending on the LinkedIn Campaign Manager UI. API calls succeed only when made with correct scopes/permissions assigned to the app after the vetting process. Once the developer application has the required permissions, all Advertising Account features can be accessed by passing identifiers from API responses in the hierarchy.

Core Components

Ad Accounts

LinkedIn enables you to create Ad Accounts for your organization's advertising campaigns. Each Ad Account supports:

  • Maximum 5,000 campaigns
  • Maximum 15,000 creatives
  • Requires Enterprise or Business Ad Account with one authenticated user as account administrator

Account Users

The Ad Account Users enables advertisers to manage ad account user access. Ad account users are members who have ad account permissions in LinkedIn Campaign Manager. Partners can control user roles for granular access management.

Campaign Groups

Campaign groups help advertisers manage status, budget, and performance across multiple related campaigns. Key features:

  • Automatically created when an Ad Account is created
  • Can contain various campaign types
  • No limit on campaign groups per advertiser account
  • Limits: 5,000 campaigns per advertiser account, 2,000 campaigns per non-default campaign group
