How a limit works
An API might let an app check order details up to 100 times a minute. After that, it may reply with 429 Too Many Requests, meaning the app should wait before trying again.
Limits can differ by account or by action. For example, creating a report might have a lower limit than checking an order.
Why limits matter
Limits help keep a service responsive and give users a fair share. A limit set too low can block ordinary use, so services should make their limits and retry times clear.
