LinkedIn Ads has a partial 16-flow static planning denominator. Four products are ordinary current-code classifications; six remain blocked. Lead Gen implementation and exact local readback exist only behind a protected exact-SHA canary gate, so ordinary buyer discovery and execution remain dark. Operation rows distinguish callable surfaces from certified behavior, and none implies fresh provider eligibility. **Review-ready, not provider-endorsed · last verified 2026-08-16.** This is an Interchange current-main compatibility snapshot, not provider certification or endorsement. “Implemented” means a provider write/read path exists. It does not mean fresh signed live evidence exists or that the selected account is currently eligible. ## Coverage and execution-package model | Layer | State | Current contract | | ----------------------------- | ----------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | Provider-observed denominator | `partial` | The current provider-creation-flow registry captures a partial 16-flow static planning denominator. It is not complete provider coverage or fresh signed live evidence. | | Wholesale product archetype | `classified` | Product rows represent materially different launch contracts. Signals, activation resources, targeting and delivery overlays, and creative choices do not create extra product rows. | | Exact execution package | `exact_static_base_plus_runtime_bindings` | Each product ID selects the current provider configuration base; account, resources, targeting, creative, budget, bid, and flight remain runtime bindings. | | Current account eligibility | `account_check_required` | Current provider permissions, market, resources, and feature eligibility must be checked for the selected account. | ## Claim provenance gaps Object-mapping and reporting rows have no exported, code-owned complete denominator on current main. They remain published because they are useful, but the contract marks the missing drift oracle instead of pretending a same-test literal prevents drift. | Claim family | State | Drift enforced | Trace sources | Gap | | ----------------- | -------------------------------- | -------------- | -------------------------------------------------------------- | ----------------------------------------------------------------------------------------------- | | `object_mappings` | `manual_plan_trace_non_enforced` | `false` | packages/storefront-adapters/src/platforms/linkedin/adapter.ts | No code-owned complete object-mapping denominator exists; these rows remain manually traced. | | `reporting` | `manual_plan_trace_non_enforced` | `false` | packages/storefront-adapters/src/platforms/linkedin/adapter.ts | No exported code-owned reporting projection constant exists; these rows are not drift-enforced. | ## Evidence state Static certification and live certification are different claims. Deterministic tests can prove code-owned catalog classifications and fail-closed behavior without contacting the provider. Object-mapping and reporting rows are validated for shape, presence, and uniqueness only; the provenance table above records that they are not compared with a complete code-owned denominator. Fresh live evidence must be dated, signed, bound to the exact account, product, resources, fixture revision, requested package, readback, no-spend result, and cleanup result. Live evidence is treated as stale after 30 days, and a newer failure overrides an older pass. | Layer | State | Last verified | What it means | | ------------------------------- | ----------------------------------------------- | ------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Static / deterministic contract | `current_code_surface_classified_not_certified` | 2026-08-16 | The partial provider-flow registry, direct catalog, callable methods, canonical format IDs, targeting dimensions, and Lead Gen fail-closed gate are regression-checked. This does not certify each provider write/read lifecycle. | | Fresh signed live evidence | `no_current_signed_full_lifecycle_artifact` | — | No currently valid dated signed full-lifecycle artifact is published for this adapter. The protected LinkedIn Lead Gen exact-SHA no-spend canary has not been promoted to ordinary buyer eligibility. | | AAO discovery | `community_catalog` | 2026-08-16 | The public registry record is discovery metadata, not provider-owned authorization or current account eligibility. | ## Markets **`account_check_required`.** No global market allowlist is asserted. This page publishes no global market allowlist. Authority: The selected account and provider response are authoritative. ## Object mapping | AdCP / Interchange | LinkedIn Ads | Mapping | | --------------------- | ------------------------------ | ---------------------------------------------------------------------------- | | `account` | `provider advertising account` | The authenticated selected account is the execution boundary. | | `media_buy` | `campaign group` | Current adapter hierarchy mapping; lifecycle certification remains separate. | | `package` | `campaign` | Budget, targeting, optimization, and flight bindings. | | `creative_assignment` | `creative` | Creative materialization or assignment surface declared by current code. | ## Operations | Public adapter operation | Surface | State | Provider path | | ------------------------ | -------------------- | ----------------- | -------------------------------------------------------------------------------------------------------------- | | `list_accounts` | AdCP buyer operation | `surface_present` | Callable current-main adapter method;

Only `executable` formats have the ordinary provider write and readback path; `canary_only` formats are restricted to governed proof, and `catalog_declared` formats are present in current code without a public ordinary-execution certification claim. `declared_not_buyer_selectable` formats are not sold through the adapter. | Format ID | Kind | State | Provider shape | | ------------------------------ | ----------------------- | ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | `linkedin_single_image` | `canonical_code_format` | `catalog_declared` | Declared by the current canonical adapter format catalog; ordinary execution is not certified by this row. | | `linkedin_video` | `canonical_code_format` | `catalog_declared` | Declared by the current canonical adapter format catalog; ordinary execution is not certified by this row. | | `linkedin_carousel` | `canonical_code_format` | `catalog_declared` | Declared by the current canonical adapter format catalog; ordinary execution is not certified by this row. | | `linkedin_lead_gen` | `canonical_code_format` | `canary_only` | Implementation and exact local readback exist, but ordinary buyer discovery and execution remain dark; access is limited to the protected exact-SHA no-spend canary pending certification. | | `linkedin_message_ad` | `canonical_code_format` | `catalog_declared` | Declared by the current canonical adapter format catalog; ordinary execution is not certified by this row. | | `linkedin_text_ad` | `canonical_code_format` | `catalog_declared` | Declared by the current canonical adapter format catalog; ordinary execution is not certified by this row. | | `linkedin_spotlight` | `canonical_code_format` | `catalog_declared` | Declared by the current canonical adapter format catalog; ordinary execution is not certified by this row. | | `linkedin_follower` | `canonical_code_format` | `catalog_declared` | Declared by the current canonical adapter format catalog; ordinary execution is not certified by this row. | | `linkedin_promoted_offerings` | `canonical_code_format` | `catalog_declared` | Declared by the current canonical adapter format catalog; ordinary execution is not certified by this row. | | `linkedin_generated_image` | `canonical_code_format` | `catalog_declared` | Declared by the current canonical adapter format catalog; ordinary execution is not certified by this row. | | `linkedin_generated_video` | `canonical_code_format` | `catalog_declared` | Declared by the current canonical adapter format catalog; ordinary execution is not certified by this row. | | `linkedin_generated_offerings` | `canonical_code_format` | `catalog_declared` | Declared by the current canonical adapter format catalog; ordinary execution is not certified by this row. | ## Placements This provider exposes no placement selector that Interchange can map without inventing inventory. ## Targeting | AdCP dimension | State | Provider mapping | | ------------------------- | ----------------- | ------------------------------------------------------------------------------------------- | | `geo_countries` | `surface_present` | Accepted by the current adapter targeting gate; provider eligibility remains account-bound. | | `geo_regions` | `surface_present` | Accepted by the current adapter targeting gate; provider eligibility remains account-bound. | | `signal_targeting_groups` | `surface_present` | Accepted by the current adapter targeting gate; provider eligibility remains account-bound. | | `signals` | `surface_present` | Accepted by the current adapter targeting gate; provider eligibility remains account-bound. | | `audience_include` | `surface_present` | Accepted by the current adapter targeting gate; provider eligibility remains account-bound. | | `audience_exclude` | `surface_present` | Accepted by the current adapter targeting gate; provider eligibility remains account-bound. | ## Reporting | AdCP output | Provider source | Notes | | ----------- | ------------------------- | -------------------------------------------------------------------------------------------------- | | `delivery` | `provider reporting task` | A delivery method is callable; exact metric parity and full-lifecycle evidence remain uncertified. | ## Conversion and audience support * **Optimization:** Product configuration is current-code classified; resource and event eligibility remain account-bound. * **Event-source setup:** A callable sync\_event\_sources surface exists; provider behavior is not certified here. * **Event ingestion:** A callable log\_event surface exists; provider behavior is not certified here. * **Audiences:** A callable audience synchronization surface exists; provider behavior is not certified here. ## Known limits * The captured partial denominator has 16 flows: 4 implemented and 12 blocked. It is a static planning registry, not complete provider coverage or fresh signed live evidence. * LinkedIn Lead Gen implementation and exact local readback are present, but ordinary buyer discovery and execution remain dark. The protected exact-SHA no-spend canary is canary-only pending certification and is not fresh provider eligibility. * Executable in the direct catalog means current-code classification, not deterministic certification, fresh signed live evidence, or present account eligibility. * Formats marked catalog\_declared are not claims of ordinary provider write/read support; linkedin\_lead\_gen is separately marked canary\_only. ## Public review endpoints * [AAO registry record](https://agenticadvertising.org/api/registry/publisher?domain=linkedin.com\&include=placements) * Staging MCP/AdCP state: `relationship_gated_storefront_id_required`. * Route template after a storefront relationship supplies its registered platform ID: `https://api.staging.interchange.io/seller/{registered_storefront_platform_id}/mcp` * No provider-ID-derived URL is published. The shared MCP route requires a registered storefront platform ID assigned to the relationship; the adapter provider ID linkedin is not asserted to be that record ID. The staging endpoint is connection-gated. Its presence here is not an invitation to send mutating requests without a jointly approved test account and canary window. ## Provider references * [LinkedIn Ads public documentation](https://learn.microsoft.com/en-us/linkedin/marketing/) ## Review questions If a provider mapping is incomplete or has changed, send the exact product, format, targeting dimension, metric, market, or provider API field that differs. We update the governed contract and add code-owned drift checks where a denominator exists; otherwise the explicit non-enforced provenance gap remains.
