Verdicts
Amazon Ads API
Public OpenAPI specifications, test accounts that serve no ads and a six-month shutoff notice policy support agent use. Access needs an approved application and an advertiser's OAuth consent, rate limits are dynamic with no published numbers, and the status feed shows three reporting disruptions since July 2026. The MCP server is in open beta.
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.
Before you call either
Amazon Ads API
- Send Amazon-Advertising-API-ClientId and a Bearer access token on every call, and Amazon-Advertising-API-Scope with a profile ID from GET /v2/profiles on most
- Call the host for the advertiser's region. advertising-api.amazon.com is North America, advertising-api-eu Europe and advertising-api-fe Far East
- Refresh the access token every 60 minutes. Refresh tokens issued from 30 July 2026 expire 365 days after consent
- On 429, wait the Retry-After seconds and back off exponentially. Request an export instead of listing every entity
- Rehearse writes in a test account, or create campaigns in the PAUSED state, before anything can spend
- For MCP, prefer https://advertising-ai.amazon.com/mcp/lite and disable delete tools in the client configuration
Meta Marketing API
- Put a version in every path, such as /v26.0/act_<AD_ACCOUNT_ID>/campaigns. Unversioned Marketing API calls fail
- Create campaigns, ad sets and ads with
status=PAUSED, and sendexecution_options=["validate_only"]first to test a write without making it - Ask for
