The Flowroute Numbers API (v1) allows you to purchase new phone numbers and manage your phone numbers over a RESTful HTTP interface.
The Numbers API (v1) only supports a Custom Authentication Scheme. You can find details about this type of authentication on the Authentication & Security page. Alternatively, API Wrapper SDKs for Python, Node.JS, Ruby, and PHP are available on Flowroute's Github. We provide you with code samples in these languages, with the custom authentication scheme being handled by the SDKs.

With the Flowroute Numbers API, you can retrieve a list of available North American area codes and exchanges served by the North American Numbering Plan (NANP), viewpurchasable phone numbers, purchase a phone number from available Flowroute inventory, as well as select primary and failover voice routes for your phone numbers.
Flowroute has migrated all functionalities around number management into Numbers v2 which is currently in beta release.
