Nextiva

Nextiva Provider Authentication API

Login and token refresh for the Nextiva Contact Center platform. Basic authentication generates a JWT bearer token carrying the user's authorities; the token-refresh operation exchanges an existing bearer token for a new one. Every other Nextiva API requires the token this API issues.
