Step by Step Guide to Building a forms.app API Integration in Go

Introduction

Hey there, fellow Go enthusiast! Ready to supercharge your forms game? Let's dive into integrating the forms.app API into your Go project. This powerful combo will let you create, manage, and analyze forms with ease. Buckle up!

Prerequisites

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

• Go installed (you're a Go dev, so I'm sure you're covered)
• A forms.app account and API key (grab one if you haven't already)
• Your favorite code editor at the ready

Setting up the project

Let's kick things off:

mkdir forms-app-integration
cd forms-app-integration
go mod init github.com/yourusername/forms-app-integration

Now, let's grab the HTTP client we'll be using:

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

Authentication

First things first, let's set up authentication. Create a new file called main.go and add this:

package main

import (
    "fmt"
    "github.com/go-resty/resty/v2"
)

const (
    baseURL = "https://forms.app/api/v1"
    apiKey  = "your-api-key-here"
)

func main() {
    client := resty.New().
        SetBaseURL(baseURL).
        SetHeader("Authorization", "Bearer "+apiKey)

    // We'll add more code here soon!
}

Making API requests

Now that we're authenticated, let's make some requests! Here's how to get a list of your forms:

resp, err := client.R().
    SetResult([]map[string]interface{}{}).
    Get("/forms")

if err != nil {
    fmt.Println("Error:", err)
    return
}

forms := resp.Result().(*[]map[string]interface{})
fmt.Printf("You have %d forms\n", len(*forms))

Implementing key features

Creating a new form

Let's create a simple form:

newForm := map[string]interface{}{
    "name": "My Awesome Go Form",
    "fields": []map[string]interface{}{
        {
            "type": "text",
            "label": "What's your name?",
        },
    },
}

resp, err := client.R().
    SetBody(newForm).
    SetResult(map[string]interface{}{}).
    Post("/forms")

if err != nil {
    fmt.Println("Error:", err)
    return
}

createdForm := resp.Result().(*map[string]interface{})
fmt.Printf("Created form with ID: %v\n", (*createdForm)["id"])

Retrieving form submissions

Now, let's fetch submissions for a form:

formID := "your-form-id-here"

resp, err := client.R().
    SetResult([]map[string]interface{}{}).
    Get("/forms/" + formID + "/submissions")

if err != nil {
    fmt.Println("Error:", err)
    return
}

submissions := resp.Result().(*[]map[string]interface{})
fmt.Printf("Form has %d submissions\n", len(*submissions))

Error handling and best practices

Always check for errors and handle them gracefully. Also, be mindful of rate limits:

if resp.StatusCode() == 429 {
    fmt.Println("Whoa there! We've hit the rate limit. Let's take a breather.")
    // Implement exponential backoff here
}

Testing the integration

Don't forget to test! Here's a simple example:

func TestCreateForm(t *testing.T) {
    // Set up your test client here
    
    newForm := map[string]interface{}{
        "name": "Test Form",
    }
    
    resp, err := client.R().
        SetBody(newForm).
        SetResult(map[string]interface{}{}).
        Post("/forms")
    
    assert.Nil(t, err)
    assert.Equal(t, 201, resp.StatusCode())
    
    createdForm := resp.Result().(*map[string]interface{})
    assert.NotNil(t, (*createdForm)["id"])
}

Conclusion

And there you have it! You've just built a forms.app API integration in Go. You're now equipped to create forms, gather submissions, and analyze data like a pro. Remember, this is just the beginning – there's so much more you can do with the forms.app API.

Keep exploring, keep coding, and most importantly, keep having fun with Go! If you run into any snags, the forms.app documentation and the awesome Go community have got your back. Now go forth and create some epic forms!
