Does the LinkedIn Ad Library have an API?

AdLib returns LinkedIn Ad Library data through a REST API: search by keyword, company, company id or domain, then fetch each ad with text, payer, impressions and targeting.

Can I see LinkedIn ad targeting?

For ads served in the EU, partly: locations, language, and which categories such as job, company or interests were used or excluded. LinkedIn does not show the values of age, gender or job targeting.

Can I see impressions or spend for LinkedIn ads?

Impressions as a bucket and a share per country, for ads served in the EU. No spend and no reach.

How far back does the LinkedIn Ad Library go?

The live search covers the last 12 months. Ads AdLib recorded earlier stay in the archive, also after LinkedIn drops them.

The same fields as every other platform, in one schema. What LinkedIn publishes is filled in; what it does not stays null.

Ad and advertiser

id: linkedin:<ad id>
advertiser.id, advertiser.name: The company page; thought-leader ads from a member profile get member:<vanity> and extra.advertiser_type member
first_shown, last_shown: The run period, on the ad detail where LinkedIn shows it
placements: Always linkedin

Creative

formats: image, video, carousel or text (message ads)
creatives[].text: Truncated in search, full on the ad detail
creatives[].headline, cta, landing_url: On the ad detail (no landing URL for carousel and video ads)

Only for ads shown in the EU

Published under the Digital Services Act; see EU reach.

Try it

Microsoft's LinkedIn ads in Germany since September. GET /v1/ads/{id} adds the full text, payer and targeting.

Media: Images and videos with their poster image on the ad detail; search results carry images and the video cover. Images are copied to media.adlibapi.com under stable URLs, and videos are archived for advertisers on a watchlist.

curl "https://api.adlibapi.com/v1/search?platform=linkedin&domain=microsoft.com&country=DE&from=2026-09-01" \

Limits

Only the last 12 months are searchable live; older ads only come from our archive.
Domain search works when the company page lists a website on the same domain.
