It's a JWT vending machine! Issue a new access token (JWT) with the provided claims in the request. This JWT is not scoped to a tenant or user, it is a free form token that will contain what claims you provide. <p> The iat, exp and jti claims will be added by FusionAuth, all other claims must be provided by the caller. If a TTL is not provided in the request, the TTL will be retrieved from the default Tenant or the Tenant specified on the request either by way of the X-FusionAuth-TenantId request header, or a tenant scoped API key.
