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

Aug 15, 20245 minute read

Hey there, fellow Go enthusiast! Ready to dive into the world of Givebutter API integration? Let's roll up our sleeves and get coding!

Introduction

Givebutter's API is a powerful tool for managing fundraising campaigns and donations. In this guide, we'll walk through building a robust integration that'll have you interacting with Givebutter's platform like a pro.

Prerequisites

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

  • Go installed (you're a Go dev, so I'm sure you're covered!)
  • Givebutter API credentials (grab 'em from your Givebutter dashboard)
  • Your favorite Go IDE fired up and ready to go

Setting up the project

Let's kick things off by setting up our project:

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

Authentication

First things first, let's handle authentication:

package main import ( "net/http" ) const apiKey = "your-api-key-here" func createClient() *http.Client { return &http.Client{ Transport: &apiKeyTransport{}, } } type apiKeyTransport struct{} func (t *apiKeyTransport) RoundTrip(req *http.Request) (*http.Response, error) { req.Header.Set("Authorization", "Bearer "+apiKey) return http.DefaultTransport.RoundTrip(req) }

Making API requests

Now, let's make some requests! Here's a quick example to fetch campaigns:

func getCampaigns(client *http.Client) ([]byte, error) { resp, err := client.Get("https://api.givebutter.com/v1/campaigns") if err != nil { return nil, err } defer resp.Body.Close() return ioutil.ReadAll(resp.Body) }

Data models

Let's define some structs to work with Givebutter's data:

type Campaign struct { ID string `json:"id"` Name string `json:"name"` Goal int `json:"goal"` Raised int `json:"raised"` } type Donation struct { Amount int `json:"amount"` CampaignID string `json:"campaign_id"` DonorEmail string `json:"donor_email"` }

Implementing key features

Here's how you might list campaigns:

func listCampaigns(client *http.Client) ([]Campaign, error) { data, err := getCampaigns(client) if err != nil { return nil, err } var campaigns []Campaign err = json.Unmarshal(data, &campaigns) return campaigns, err }

Error handling and logging

Don't forget to implement robust error handling:

func handleError(err error) { if err != nil { log.Printf("Error: %v", err) // Add your error handling logic here } }

Testing

Testing is crucial. Here's a simple test for our getCampaigns function:

func TestGetCampaigns(t *testing.T) { client := createClient() _, err := getCampaigns(client) if err != nil { t.Errorf("getCampaigns() returned an error: %v", err) } }

Best practices

Remember to implement rate limiting to be a good API citizen, and always keep your API key secure. Never commit it to version control!

Conclusion

And there you have it! You've just built a solid foundation for your Givebutter API integration in Go. From here, you can expand on this base, adding more features and fine-tuning your implementation.

Keep exploring the Givebutter API docs for more endpoints to integrate, and don't hesitate to reach out to their support if you hit any snags.

Happy coding, and may your fundraising efforts be fruitful!
