Twilio

go get github.com/KARTIKrocks/gosms/twilio

Configuration

provider, err := twilio.NewProvider(twilio.Config{
    AccountSID: "account_sid",
    AuthToken:  "auth_token",
    From:       "+15551234567",
})
if err != nil {
    log.Fatal(err)
}

client := gosms.NewClient(provider)
result, err := client.Send(ctx, "+15559876543", "Hello from gosms!")

Field	Purpose
AccountSID, AuthToken	Twilio API credentials
From	Default sender number, used when a Message doesn't set From
MessagingServiceSID	Optional — route through a Messaging Service instead of a single From number
StatusCallback	Optional — URL Twilio posts delivery status updates to
HTTPClient	Optional — override the default *http.Client
BaseURL	Optional — override the Twilio API base URL (testing)

Scheduled messages

Twilio is the only provider that supports WithSchedule:

msg := gosms.NewMessage("+15559876543", "Reminder: your appointment is tomorrow").
    WithSchedule(time.Now().Add(24 * time.Hour))

result, err := client.SendMessage(ctx, msg)

Webhook

twilio.ParseWebhook matches the gosms.WebhookParser signature — see Webhooks for the shared pattern:

http.HandleFunc("/webhook/twilio", func(w http.ResponseWriter, r *http.Request) {
    status, err := twilio.ParseWebhook(r)
    if err != nil {
        http.Error(w, err.Error(), http.StatusBadRequest)
        return
    }

    log.Printf("Message %s status: %s", status.MessageID, status.Status)
    w.WriteHeader(http.StatusOK)
})
