APNs binary API provider will not work properly without certificate file required for authorization by APNs and password to decrypt this certificate file. You need to get certificate using Apple Developer Account.

When you have this certificate, you need to pass path to certificate file as cert-file property, password as cert-password and APNS topic (bundle id) as apns-topic.

Example for /etc/apns-cert.p12, Pa$$word and com.bundle.id. 

push () {
    'apns-binary-api' () {
        'cert-file' = '/etc/apns-cert.p12'
        'cert-password' = 'Pa$$w0rd'
        'apns-topic' = 'com.bundle.id'
    }
}
