Step by Step Guide to Building a Cisco Webex API Integration in Go

Hey there, fellow Go enthusiast! Ready to dive into the world of Cisco Webex API integration? Buckle up, because we're about to embark on a journey that'll have you sending messages, managing rooms, and handling webhooks like a pro. Let's get started!

Prerequisites

Before we jump in, make sure you've got:

• Go installed (you're a Go dev, so I'm sure you've got this covered)
• A Webex Teams account (if you don't have one, go grab it – it's free!)
• An API access token (head over to the Webex Developer site to snag one)

Setting Up the Project

First things first, let's create a new Go module and grab the webexteams package:

mkdir webex-integration && cd webex-integration
go mod init webex-integration
go get github.com/jbogarin/go-cisco-webex-teams

Initializing the Webex Client

Now, let's get that client up and running:

package main

import (
    "fmt"
    "os"

    webexteams "github.com/jbogarin/go-cisco-webex-teams/sdk"
)

func main() {
    client := webexteams.NewClient()
    client.SetAuthToken(os.Getenv("WEBEX_ACCESS_TOKEN"))

    // We're ready to rock!
}

Pro tip: Keep that access token safe in an environment variable. Your future self will thank you!

Basic Operations

Listing Rooms

Let's see what rooms we've got:

rooms, _, err := client.Rooms.List()
if err != nil {
    fmt.Println("Error listing rooms:", err)
    return
}

for _, room := range rooms.Items {
    fmt.Printf("Room: %s (ID: %s)\n", room.Title, room.ID)
}

Sending Messages

Time to spread some cheer:

message := &webexteams.MessageCreateRequest{
    RoomID: "ROOM_ID_HERE",
    Text:   "Hello, Webex! This message was sent using Go!",
}

_, _, err := client.Messages.Create(message)
if err != nil {
    fmt.Println("Error sending message:", err)
    return
}

Reading Messages

Let's see what people are chatting about:

messages, _, err := client.Messages.ListWithOptions(&webexteams.ListMessagesOptions{
    RoomID: "ROOM_ID_HERE",
})
if err != nil {
    fmt.Println("Error listing messages:", err)
    return
}

for _, msg := range messages.Items {
    fmt.Printf("Message from %s: %s\n", msg.PersonEmail, msg.Text)
}

Advanced Features

Creating and Managing Teams

Let's build a dream team:

team, _, err := client.Teams.Create(&webexteams.TeamCreateRequest{
    Name: "Go Gophers",
})
if err != nil {
    fmt.Println("Error creating team:", err)
    return
}

fmt.Printf("Team created: %s (ID: %s)\n", team.Name, team.ID)

Handling Webhooks

Stay in the loop with webhooks:

webhook, _, err := client.Webhooks.Create(&webexteams.WebhookCreateRequest{
    Name:      "My Go Webhook",
    TargetURL: "https://your-webhook-url.com",
    Resource:  "messages",
    Event:     "created",
})
if err != nil {
    fmt.Println("Error creating webhook:", err)
    return
}

fmt.Printf("Webhook created: %s (ID: %s)\n", webhook.Name, webhook.ID)

File Sharing

Share those memes... I mean, important documents:

file, err := os.Open("important.pdf")
if err != nil {
    fmt.Println("Error opening file:", err)
    return
}
defer file.Close()

message, _, err := client.Messages.CreateWithAttachment(&webexteams.MessageCreateRequest{
    RoomID: "ROOM_ID_HERE",
    Text:   "Check out this important document!",
}, file)
if err != nil {
    fmt.Println("Error sending file:", err)
    return
}

fmt.Println("File sent successfully!")

Error Handling and Best Practices

Always check for errors and handle them gracefully. The webexteams package returns detailed error information, so make use of it!

For rate limits, implement exponential backoff:

func retryWithBackoff(operation func() error) error {
    backoff := time.Second
    for i := 0; i < 5; i++ {
        err := operation()
        if err == nil {
            return nil
        }
        if strings.Contains(err.Error(), "Rate Limit") {
            time.Sleep(backoff)
            backoff *= 2
            continue
        }
        return err
    }
    return fmt.Errorf("operation failed after 5 retries")
}

Testing Your Integration

For unit tests, use Go's built-in testing package and mock the Webex API responses. For integration tests, create a separate test account and use real API calls (but please, be gentle with the API).

Deployment Considerations

When deploying, remember:

• Use environment variables for API tokens
• Consider containerizing your app for easy deployment
• Implement proper logging and monitoring

Conclusion

And there you have it! You're now equipped to build some seriously cool Webex integrations with Go. Remember, the webexteams package has a ton more features we didn't cover here, so don't be afraid to explore.

Keep coding, keep learning, and most importantly, have fun! If you get stuck, the Webex Developer docs and the Go community are always there to help. Now go forth and build something awesome!
