Add LinkedIn Creative

USE THIS TOOL WHEN: User wants to add another IMAGE ad/creative to an EXISTING LinkedIn image campaign.

DO NOT USE to create a new campaign. For new campaigns:

Image → create_linkedin_image_campaign
Video → create_linkedin_video_campaign
Carousel → create_linkedin_carousel_campaign
Text → create_linkedin_text_campaign

DO NOT USE for different audiences/targeting. For different audiences: → Use add_linkedin_campaign_to_group instead (creates a new campaign in the same group).

KEY DISTINCTION:

Same audience, different creative/copy → use THIS tool
Different audience/targeting → use add_linkedin_campaign_to_group instead

Common scenarios:

A/B test ad copy: Different headlines, introductory text, or CTAs
A/B test images: Different images for same audience
LinkedIn recommends 4+ ads per campaign for optimal performance

Required Parameters:

campaign_id: Campaign to add creative to
organization_id: Organization for ad authoring
image_urn: Image asset URN
introductory_text: Main ad copy
landing_page_url: Destination URL
