API for number port out

We're a VOIP phone company. We need to setup an API to talk to our carriers that when a number is ported out we get an email say XYZ number is porting out do you approve yes or no. The Port-out Validation API allows approved and contracted customers to confirm the validity of port-out requests on submission, to ensure that the requests include the required FCC-permitted elements of subscriber data, in an attempt to reduce invalid requests. This API will cause a synchronous API call to the endpoint configured for the account, and expect a response indicating the validity of the data, or any errors found in the data.
