Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for application programming interface (API) request throttling. A request throttling system monitors incoming API requests and applies delays to repeated API requests to avoid an overload and/or disruption in service. Upon receiving an API request from a requesting device, the request throttling system determines a counter value that is used to determine whether to apply a delay to API request. The counter value indicates a number or previous requests received from the requesting device that were directed to the same resource and which resulted in an error. The request throttling system compares the counter value to a threshold value to determine whether to apply a delay to the API request. Applying a delay reduces the speed at which subsequent repeat API requests are received from the requesting device, while still allowing for API requests from the requesting device to be processed.

Abstract: A system and method for regional routing of internet protocol based real-time communication that includes registering a set of client application endpoint routes, comprising registering at least a first client gateway route of a first endpoint in a first region; receiving a communication invitation of the first endpoint; processing a set of communication instructions associated with the communication invitation and identifying a set of communication resources and at least a second endpoint; querying the client application endpoint routes and identifying a client gateway route of the second endpoint; and dynamically directing signaling path and media path of the communication according to the regional availability of the communication resources, the client gateway route of the first endpoint, and client gateway instance route of the second endpoint.
