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

Introduction

Hey there, fellow Go enthusiast! Ready to dive into the world of Paperform API integration? You're in for a treat. We'll be building a sleek, efficient integration that'll make your forms work harder than ever. Let's get cracking!

Prerequisites

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

• Go installed (I know, obvious, right?)
• A Paperform account with an API key
• Your favorite code editor at the ready

Setting up the project

First things first, let's get our project structure sorted:

mkdir paperform-integration
cd paperform-integration
go mod init paperform-integration

Now, let's grab the packages we'll need:

go get github.com/go-resty/resty/v2

Authentication

Alright, time to get cozy with the Paperform API. We'll use your API key for all our requests:

import "github.com/go-resty/resty/v2"

client := resty.New()
client.SetHeader("Authorization", "Bearer YOUR_API_KEY")

Basic API Requests

Let's start with something simple - fetching your forms:

resp, err := client.R().
    SetResult(&[]Form{}).
    Get("https://api.paperform.co/v1/forms")

if err != nil {
    log.Fatal(err)
}

forms := resp.Result().(*[]Form)

Working with Form Submissions

Now for the fun part - submitting form data:

submission := map[string]interface{}{
    "field_1": "Hello, Paperform!",
    "field_2": 42,
}

resp, err := client.R().
    SetBody(submission).
    Post("https://api.paperform.co/v1/submissions/FORM_ID")

if err != nil {
    log.Fatal(err)
}

Error Handling

Let's not forget about error handling. Always check your responses:

if resp.IsError() {
    log.Printf("API error: %v", resp.Error())
    return
}

Advanced Features

Feeling adventurous? Let's set up a webhook to receive real-time updates:

http.HandleFunc("/webhook", func(w http.ResponseWriter, r *http.Request) {
    // Handle incoming webhook data
})

Testing

Testing is crucial. Here's a quick example using the testing package:

func TestGetForms(t *testing.T) {
    // Mock API response
    // Test your GetForms function
}

Performance Optimization

For better performance, consider implementing caching:

var cache = make(map[string]interface{})

func getCachedData(key string) (interface{}, bool) {
    data, found := cache[key]
    return data, found
}

Deployment Considerations

When deploying, remember to use environment variables for sensitive info:

apiKey := os.Getenv("PAPERFORM_API_KEY")

Conclusion

And there you have it! You've just built a robust Paperform API integration in Go. Pretty cool, right? Remember, this is just the beginning. There's a whole world of possibilities out there with the Paperform API. So go forth and create something awesome!
