Access needs LinkedIn's approval and a member's OAuth consent, standard rate limits are not published, and no OpenAPI specification was found.\n\n**Microsoft Advertising API.** Version 13 covers campaigns, budgets, audiences, ads and reports over REST with JSON, with a sandbox that needs no payment method and four official SDKs. Call-rate limits are unpublished, no public OpenAPI file or idempotency key was found, and one OAuth scope covers every operation. The SOAP interface retires on 31 January 2027.\n\n## Before you call either\n\n### LinkedIn Marketing APIs\n\n1. 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)\n2. 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\n3. Create campaigns as DRAFT or PAUSED and check `servingStatuses` before activating. Some validation is postponed until activation\n4. Pass `fields=` on adAnalytics. Responses stop at 15,000 elements and the endpoint throttles at 45 million metric values per 5 minutes\n5. On Development tier, map each ad account to the app in the Developer Portal. Edits are limited to five accounts\n\n### Microsoft Advertising API\n\n1. Build and test against the sandbox hosts (`*.api.sandbox.bingads.microsoft.com`) with developer token BBD37VB98. Sandbox and production credentials are separate\n2. Send `Authorization: Bearer \u003ctoken\u003e`, `DeveloperToken`, `CustomerId` and `CustomerAccountId` on REST calls. Use the account ID, never the eight-character account number\n3. Create campaigns with `Status` set to `Paused`, then read them back before activating. No validate-only mode was found\n4. On error 117 (CallRateExceeded) wait 60 seconds. On Bulk error 4204 wait up to 15 minutes\n5. Read `PartialErrors` on every add, update and delete. A call can succeed for some items and fail for others\n\n## Questions\n\n### Which is better for AI agents, LinkedIn Marketing APIs or Microsoft Advertising API?\n\nLinkedIn Marketing APIs scores 62.4 (B) on agent readiness against Microsoft Advertising API's 60.3 (C), and leads in 4 of 7 scored categories.
