Apple Ads Platform API vs Snapchat Ads 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.

Snapchat Ads API

The docs are served as Markdown with an llms.txt index, rate limits are published as 20 requests a second per app and 10 per token, and test ad accounts never serve live ads. No OpenAPI specification, status page, SLA, idempotency key or Ads API SDK was found, and one OAuth scope covers both reads and writes.

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

Snapchat Ads API

1. Refresh the access token every 60 minutes with the refresh token. An expired token returns 401 with WWW-Authenticate: Bearer error="invalid_token"
2. Create a test ad account with "test": true and build there first, and create campaigns with "status": "PAUSED"
3. Change one field with PATCH (JSON Patch). A PUT that omits attributes resets them to their defaults
4. Send money as micro-currency, where 1.00 of the account currency is 1,000,000
5. Page lists with limit (50 to 1,000) and follow paging.next_link. Use async=true for large stats pulls, since an oversized response fails with E9001 and a retry does not help
