Apple Ads Platform API vs Meta Marketing API

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.

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.

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

Meta Marketing API

1. Put a version in every path, such as /v26.0/act_<AD_ACCOUNT_ID>/campaigns. Unversioned Marketing API calls fail
2. Create campaigns, ad sets and ads with status=PAUSED, and send execution_options=["validate_only"] first to test a write without making it
3. Ask for ads_read alone when the task is reporting. ads_management can change budgets and activate spend
4. Read X-Business-Use-Case-Usage and X-Ad-Account-Usage after each call and wait for estimated_time_to_regain_access on errors 17, 613 and 80004
5. Change an ad set budget at most four times an hour and an account spending limit at most ten times a day
