## Which one, for what

### Apple Ads Platform API (D)

Good for: An agent that manages or reports on App Store search campaigns, or Apple Maps campaigns, for an advertiser whose administrator can grant an API role.

Ahead on:
- Agent ergonomics, 69 against 63

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: The Platform API was first released in August 2026 and its changelog has one entry. The Campaign Management API 5 it replaces is sunset on 26 January 2027

### LinkedIn Marketing APIs (B)

Good for: An agent that reports on and manages LinkedIn campaigns for accounts its operator administers, especially read-only reporting, which has no account limit on Development tier.

Ahead on:
- Reliability, 66 against 35
- Payments & pricing, 30 against 20
- Maintenance & community, 64 against 48
- Transparency & trust, 84 against 66

Watch for: Standard rate limits are not published. An app sees its limit in the Developer Portal only after calling the endpoint

## Verdicts

**Apple Ads Platform API.** Every response carries `RateLimit-*` headers and a 429 carries `Retry-After`, Apple maintains MIT client libraries in four languages, and read-only API roles exist. The API was first released in August 2026. No status page, SLA, published OpenAPI file, idempotency key or test account was found, and a person must create the credentials in the Apple Ads interface.

**LinkedIn Marketing APIs.** Monthly API versions are each supported for at least a year, with dated sunsets and a changelog, and a test ad account lets an agent create campaigns that are never served or billed. Access needs LinkedIn's approval and a member's OAuth consent, standard rate limits are not published, and no OpenAPI specification was found.

## Before you call either

### Apple Ads Platform API

1. Send `Authorization: Bearer {access_token}` and `X-AP-Context: adAccountId={adAccountId}` on every ad account call. Get the account id from `GET /v1/acls`
2. Request a new access token every 3,600 seconds from `https://appleid.apple.com/auth/oauth2/token` with scope `searchadsorg`. The signed client secret lasts at most 180 days
3. Read `RateLimit-Remaining` on each response. On a 429 wait the `Retry-After` seconds, then double the wait up to 16 seconds
4. List and filter with POST to a `/query` endpoint, not GET with query parameters. Deleted entities return only when a filter asks for them
5. On PUT send only the fields to change, and send the complete desired array for any array field. Create campaigns with `"status": "PAUSED"` before review

### LinkedIn Marketing APIs

1. Send `Linkedin-Version: YYYYMM` and `X-Restli-Protocol-Version: 2.0.0` on every call. A missing or sunset version returns an error (426 for a deprecated one)
2. Create one test ad account with `"test": true` and build there first. Its creatives are auto-rejected and never billed, and it returns no reporting data
3. Create campaigns as DRAFT or PAUSED and check `servingStatuses` before activating. Some validation is postponed until activation
4. Pass `fields=` on adAnalytics. Responses stop at 15,000 elements and the endpoint throttles at 45 million metric values per 5 minutes
5. On Development tier, map each ad account to the app in the Developer Portal. Edits are limited to five accounts
