Step by Step Guide to Building a Calendly API Integration in Go

Jul 31, 2024 • 6 minute read

Introduction

Hey there, fellow Go enthusiast! Ready to supercharge your scheduling game? Let's dive into building a Calendly API integration using the awesome go-calendly package. Calendly's API opens up a world of possibilities for automating and customizing your scheduling workflows. Buckle up, because we're about to make your life a whole lot easier!

Prerequisites

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

Go installed on your machine (you're a Gopher, right?)
A Calendly account with an API key (if you don't have one, go grab it!)
Some basic Go skills and a general understanding of RESTful APIs

Got all that? Great! Let's get coding!

Setting up the project

First things first, let's create a new Go project and grab the go-calendly package:

mkdir calendly-integration
cd calendly-integration
go mod init calendly-integration
go get github.com/getbouncer/go-calendly

Initializing the Calendly client

Now, let's create our main.go file and set up the Calendly client:

package main

import (
    "fmt"
    "github.com/getbouncer/go-calendly"
)

func main() {
    client := calendly.NewClient("YOUR_API_KEY")
    // We'll add more code here soon!
}

Replace "YOUR_API_KEY" with your actual Calendly API key. Easy peasy!

Implementing key Calendly API features

Fetching user information

Let's start by getting some info about the current user:

user, err := client.GetCurrentUser()
if err != nil {
    fmt.Printf("Error fetching user: %v\n", err)
    return
}
fmt.Printf("Current user: %s\n", user.Name)

Retrieving event types

Now, let's fetch the user's event types:

eventTypes, err := client.ListEventTypes()
if err != nil {
    fmt.Printf("Error fetching event types: %v\n", err)
    return
}
for _, et := range eventTypes {
    fmt.Printf("Event type: %s\n", et.Name)
}

Creating a new event

Want to create a new event? Here's how:

newEvent := &calendly.Event{
    Name: "Coffee Chat",
    Color: "#0088cc",
    Duration: 30,
}
createdEvent, err := client.CreateEvent(newEvent)
if err != nil {
    fmt.Printf("Error creating event: %v\n", err)
    return
}
fmt.Printf("Created event: %s\n", createdEvent.Name)

Managing scheduled events

Let's fetch and display some scheduled events:

events, err := client.ListEvents()
if err != nil {
    fmt.Printf("Error fetching events: %v\n", err)
    return
}
for _, e := range events {
    fmt.Printf("Scheduled event: %s at %s\n", e.Name, e.StartTime)
}

Error handling and best practices

As you've seen, we're checking for errors after each API call. This is crucial! Always handle errors gracefully to keep your integration robust. Consider implementing more detailed error logging for production use.

Testing the integration

Give your code a whirl! Run it and make sure everything's working as expected. Don't be afraid to experiment and add more features – the sky's the limit!

Conclusion

And there you have it! You've just built a solid foundation for a Calendly API integration in Go. Pretty cool, right? This is just the tip of the iceberg – there's so much more you can do with the Calendly API. Why not try implementing webhooks next, or dive deeper into event management?
