 6All methods have been added, and all features should be available.
 7If you want a feature that hasn't been added yet or something is broken, open an issue and I'll see what I can do.
 8
 9All methods are fairly self explanatory, and reading the godoc page should explain everything. If something isn't clear, open an issue or submit a pull request.
10
11The scope of this project is just to provide a wrapper around the API without any additional features. There are other projects for creating something with plugins and command handlers without having to design all that yourself.
12
13## Example
14
15This is a very simple bot that just displays any gotten updates, then replies it to that chat.
16
17```go
18package main
19
20import (
21	"log"
22	"github.com/zhulik/telegram-bot-api"
23)
24
25func main() {
26	bot, err := tgbotapi.NewBotAPI("MyAwesomeBotToken")
27	if err != nil {
28		log.Panic(err)
29	}
30
31	bot.Debug = true
32
33	log.Printf("Authorized on account %s", bot.Self.UserName)
34
35	u := tgbotapi.NewUpdate(0)
36	u.Timeout = 60
37
38	updates, err := bot.GetUpdatesChan(u)
39
40	for update := range updates {
41		log.Printf("[%s] %s", update.Message.From.UserName, update.Message.Text)
42
43		msg := tgbotapi.NewMessage(update.Message.Chat.ID, update.Message.Text)
44		msg.ReplyToMessageID = update.Message.MessageID
45
46		bot.Send(msg)
47	}
48}
49```
50
51If you need to use webhooks for some reason (such as running on Google App Engine), you may use a slightly different method.
52
53```go
54package main
55
56import (
57	"github.com/zhulik/telegram-bot-api"
58	"log"
59	"net/http"
60)
61
62func main() {
63	bot, err := tgbotapi.NewBotAPI("MyAwesomeBotToken")
64	if err != nil {
65		log.Fatal(err)
66	}
67
68	bot.Debug = true
69
70	log.Printf("Authorized on account %s", bot.Self.UserName)
71
72	_, err = bot.SetWebhook(tgbotapi.NewWebhookWithCert("https://www.google.com:8443/"+bot.Token, "cert.pem"))
73	if err != nil {
74		log.Fatal(err)
75	}
76
77	updates, _ := bot.ListenForWebhook("/" + bot.Token)
78	go http.ListenAndServeTLS("0.0.0.0:8443", "cert.pem", "key.pem", nil)
79
80	for update := range updates {
81		log.Printf("%+v\n", update)
82	}
83}
84```
85
86If you need, you may generate a self signed certficate, as this requires HTTPS / TLS. The above example tells Telegram that this is your certificate and that it should be trusted, even though it is not properly signed.
87
88    openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 3560 -subj "//O=Org\CN=Test" -nodes
