Limits are set per merchant account. If your integration needs more throughput, raise a request from Dashboard → Support with your expected peak volume.

⚠ Handle 429 properly

Back off and retry after the interval in the Retry-After header rather than retrying immediately — tight retry loops extend the throttle window.
