Do APIs have a rate limit during cloud-cloud docking?

Yes. The limit for app traffic is 500,000 times per day. The app traffic is assigned to developers to invoke APIs. Each API invocation request to the Tuya Smart platform, regardless of success or failure, counts as one time. This prevents developers from always sending requests to the Tuya Smart platform. The limit for API traffic is 500 times per second. Each developer is assigned a traffic limit to invoke APIs, for example, the API for obtaining device information. This prevents backend faults caused by a large number of invocations. The API traffic limit mechanism is to protect the system.
