LinkedIn Ads compatibility

This page compares the LinkedIn Ads capabilities represented in the Apostra adapter with what Apostra currently makes available to buyers. It answers a practical question: what can I do through Apostra today, and what would still require another path?

Last reviewed 2026-08-18. This is Apostra’s description of its own adapter, based on the implementation and the linked provider documentation. LinkedIn Ads has not reviewed or endorsed this page. Availability can still vary by account permissions, market, and provider access.

How to read availability

🟢 Available — Offered through Apostra now, subject to your ad account’s permissions and eligibility with the provider.
🟡 Partial — Some of the workflow is available; the Comments column explains the boundary.
🔵 Testing — Apostra is validating the workflow before offering it broadly.
⚪ Planned — Not offered through Apostra yet. The provider may still support it directly; Comments explains why and links a roadmap reference.

Roadmap

The adapter roadmap is tracked in AI-3806 (a plain-text reference — Apostra’s internal issue tracker is not public). This roadmap tracks LinkedIn product completeness, provider access, and live readiness. Every row that is not currently available shows that reference or a more specific one in its References column, so customers and partners can quote a stable identifier when asking about a capability.

Connection, accounts, and identity

LinkedIn Ads connects to Apostra through an OAuth grant. Connecting a Organization account gives Apostra access to each Ad account (sponsored account) it can reach — you then map each one to your advertisers. The mapped account decides which LinkedIn Ads tenant a buy runs on: a media buy for an unmapped advertiser fails closed with account_mapping_required rather than silently using another account. Connection, account-discovery, and revocation behavior is the same across ad platforms — see Platform accounts and advertiser mapping for the full model and the LinkedIn Ads section of the connecting guide for LinkedIn Ads-specific permissions.

Apostra concept	LinkedIn Ads concept	What it represents
Account (`account`)	provider advertising account	The authenticated selected account is the execution boundary.
Media Buy (`media_buy`)	campaign	One exact campaign remains the media-buy identity and validates its account-owned parent campaign group. New campaigns commit independently versioned durable package or catalog inventory before activation and fail closed if it is lost; legacy unmarked campaigns are labeled unverified and never claim catalog attribution.
Package (`package`)	campaign	Budget, targeting, optimization, and flight bindings.
Creative Assignment (`creative_assignment`)	creative	Creative materialization or assignment surface declared by current code.

Sync Event Sources	🟢 Available	LinkedIn Ads public documentation	If your LinkedIn connection predates this release, reconnect it to grant rw_conversions; then call sync_event_sources again and replace any stored event_source_id — the previous synthetic identifier no longer resolves. Returns one event source per enabled LinkedIn Conversions API rule in the selected account instead of a single synthetic tag derived from the account ID. An account with more than 500 eligible rules gets a clear error on unfiltered discovery instead of a partial list — request the specific event_source_id values you need instead. Those account-scoped exact reads are chunked to 100 IDs, do not drain the full inventory, and treat only an explicit LinkedIn 404 as absent; permission, throttling, malformed-response, and provider failures remain visible errors.
Log Event	🟢 Available	LinkedIn Ads public documentation	Accepts events only for a conversion rule discovered by sync_event_sources that is still enabled and owned by the selected account, and rejects an event whose type doesn’t match that rule. Every event must identify the user with a lowercase SHA-256 hashed email, a LinkedIn li_fat_id, or one advertiser-owned external ID. If custom_data.value is present, custom_data.currency is required; Apostra never assumes USD. Invalid input rejects the complete call before anything is sent to LinkedIn.

Reporting

Apostra reports LinkedIn Ads delivery day by day (there is no hourly delivery breakdown), aggregated nightly from adapter-reported delivery, in the advertiser’s home currency using the booked or historical exchange rate — any cross-currency rollup is always labeled an estimate and is never used for billing. See Reporting overview for the full model. Apostra does not currently publish an attribution-finality window for LinkedIn Ads; the table below lists every metric the adapter surfaces today.

Webhooks and async lifecycle

LinkedIn Ads does not push status, delivery, or reporting events into Apostra — every campaign product declares supports_webhooks: false.

Status. Apostra does not currently poll LinkedIn Ads in the background for creative or media-buy status changes; status reflects what the adapter returned on your last call.
Delivery. Apostra has not yet made on-demand delivery fetching generally available for LinkedIn Ads — see Get Media Buy Delivery in “What the adapter can do” above. The /reporting/metrics endpoints never call the adapter either way — they read from a separately-populated store (see Reporting below), so a reporting request does not itself refresh provider delivery.

This is separate from Apostra’s own buyer webhook subscriptions — an unrelated account-level event feed (currently discovery.revision only), documented in Buyer webhooks.

Market and account availability

Apostra does not promise that every feature is enabled for every account or market. Availability is checked against your selected ad account rather than a global market list on this page.

Important limitations

Apostra implementation/testing. Apostra has reviewed 18 LinkedIn creation flows, but this is not yet a confirmed complete catalog of every LinkedIn Ads workflow.
Apostra implementation/testing. Four campaign products exist in the current adapter code but are still being certified before general availability.
Apostra implementation/testing. Lead Gen and Website Conversions are still being tested and are not generally available; the other unavailable product rows have not been implemented end to end.
the ad platform’s API or your account’s eligibility. LinkedIn account permissions, forms, audiences, and objective eligibility can further narrow availability.
