Steps
Handle HTTP 429 responses by reading the Retry-After header and waiting that many seconds before retrying.
Treat Amazon Ads API throttling as dynamic based on overall system load rather than a fixed published quota.
For reporting endpoints, expect rate limits to vary with the current size of the reporting generation queue in your region.
Implement exponential backoff with jitter as a fallback for any endpoint that doesn't return a clear Retry-After.
Refresh your OAuth access token proactively using the stored refresh token before it expires rather than waiting for a 401.
Known gotchas
Unlike Amazon's SP-API, the Ads API does not expose numeric rate-limit-remaining headers - the only throttle signal is the 429 response plus Retry-After.
Reporting rate limits are regional and queue-dependent, so an identical request can succeed or throttle depending on time of day and region load.
Access tokens are short-lived (roughly an hour); long-running batch jobs need refresh-token rotation logic, not a single token fetched at start.
