Throughput Limits


API Interface: HTTP API v4

The Aerialink HTTP API imposes two types of limits on the throughput use of our API unless special arrangements have been made. These limits exist to protect the Aerialink network as well as adhere to operator/carrier requirements. If you need your limits adjusted, please contact the Aerialink Support Team with a change request and an explanation for the change. Any violation of your account/resource limits may subject your service to immediate termination.

For more information about how our throughput rates are calculated, consult our Throughput Calculations Chart
