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

Jul 31, 2024 • 6 minute read

Introduction

Hey there, fellow Go enthusiast! Ready to supercharge your forms with Typeform's API? In this guide, we'll walk through building a slick Typeform API integration using the gotypeform package. Buckle up, because we're about to make form data management a breeze!

Prerequisites

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

Go installed on your machine (you're a Gopher, right?)
A Typeform account with an API key (if you don't have one, grab it from your account settings)
Some basic Go skills and API know-how (but don't worry, we'll keep it simple)

Setting Up the Project

Let's kick things off by creating a new Go project:

mkdir typeform-integration
cd typeform-integration
go mod init typeform-integration

Now, let's bring in the star of the show - the gotypeform package:

go get github.com/typeform/go-typeform

Initializing the Typeform Client

Time to get our hands dirty with some code. First, let's import the necessary packages and create our Typeform client:

package main

import (
    "fmt"
    "github.com/typeform/go-typeform"
)

func main() {
    client := typeform.NewClient("YOUR_API_KEY_HERE")
    // We're ready to rock!
}

Fetching Form Responses

Now that we're all set up, let's grab some form data:

// Get a list of forms
forms, err := client.Forms.List()
if err != nil {
    fmt.Printf("Oops! Couldn't fetch forms: %v\n", err)
    return
}

// Get responses for a specific form
responses, err := client.Responses.List("FORM_ID_HERE")
if err != nil {
    fmt.Printf("Uh-oh! Couldn't fetch responses: %v\n", err)
    return
}

Processing and Analyzing Responses

Great! We've got our responses. Let's make sense of this data:

for _, response := range responses.Items {
    fmt.Printf("Response ID: %s\n", response.ResponseID)
    for _, answer := range response.Answers {
        fmt.Printf("Question: %s, Answer: %v\n", answer.Field.Title, answer.Text)
    }
}

Implementing Webhook Support (Optional)

Want real-time updates? Let's set up a webhook:

http.HandleFunc("/webhook", func(w http.ResponseWriter, r *http.Request) {
    // Parse the incoming webhook data
    // Process it as needed
})

http.ListenAndServe(":8080", nil)

Error Handling and Best Practices

Always check for errors and respect rate limits:

if err != nil {
    // Handle the error gracefully
}

// Add a small delay between requests to avoid hitting rate limits
time.Sleep(time.Millisecond * 100)

Testing the Integration

Don't forget to test! Here's a simple unit test to get you started:

func TestFetchResponses(t *testing.T) {
    client := typeform.NewClient("TEST_API_KEY")
    responses, err := client.Responses.List("TEST_FORM_ID")
    if err != nil {
        t.Errorf("Expected no error, got %v", err)
    }
    if len(responses.Items) == 0 {
        t.Error("Expected responses, got none")
    }
}

Conclusion

And there you have it! You've just built a Typeform API integration in Go. Pretty cool, right? With this foundation, you can now fetch form data, process responses, and even set up real-time webhooks. The possibilities are endless!

Remember, this is just the beginning. Feel free to explore more of the Typeform API and the gotypeform package. Maybe add some data visualization or integrate with other services? The sky's the limit!
