Verdicts
Meta Marketing API
Reporting, campaign, budget, audience and creative endpoints sit behind ads_read and ads_management scopes, with a validate_only option and sandbox ad accounts for checking a change before it spends. New apps are held to a score of 60 per ad account, with a 300-second block at the limit, and the documented requests pass the access token as a parameter.
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 Call-rate limits are unpublished, no public OpenAPI file or idempotency key was found, and one OAuth scope covers every operation.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.
