Step by Step Guide to Building an RD Station API Integration in Go

Introduction

Hey there, fellow Go enthusiast! Ready to dive into the world of RD Station API integration? You're in for a treat. We'll be building a sleek, efficient integration that'll have you manipulating marketing automation data like a pro. Let's get cracking!

Prerequisites

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

• Go installed (I know you probably do, but just checking!)
• RD Station API credentials (if you don't have these, hop over to their dev portal and grab 'em)

Setting up the project

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

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

Now, let's grab the essentials:

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

Authentication

Alright, time to get that access token. Here's a quick snippet to get you started:

package main

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

func getAccessToken(clientID, clientSecret string) (string, error) {
    client := resty.New()
    resp, err := client.R().
        SetFormData(map[string]string{
            "client_id":     clientID,
            "client_secret": clientSecret,
            "grant_type":    "client_credentials",
        }).
        Post("https://api.rd.services/auth/token")

    // Handle the response and extract the token
    // Don't forget to implement token refresh!
}

Making API requests

Now that we're authenticated, let's set up our HTTP client:

func newRDClient(accessToken string) *resty.Client {
    return resty.New().
        SetHeader("Authorization", "Bearer "+accessToken).
        SetHeader("Content-Type", "application/json")
}

Implementing key API endpoints

Let's tackle the Contacts API first:

func createContact(client *resty.Client, contact Contact) error {
    _, err := client.R().
        SetBody(contact).
        Post("https://api.rd.services/platform/contacts")
    return err
}

You can follow a similar pattern for Conversions and Fields APIs. Easy peasy!

Error handling and logging

Don't forget to wrap your API calls with proper error handling:

if err := createContact(client, newContact); err != nil {
    log.Printf("Failed to create contact: %v", err)
    // Handle the error appropriately
}

Testing the integration

Time to make sure everything's working smoothly. Here's a simple test to get you started:

func TestCreateContact(t *testing.T) {
    client := newRDClient(os.Getenv("RD_ACCESS_TOKEN"))
    contact := Contact{
        Name:  "John Doe",
        Email: "[email protected]",
    }
    err := createContact(client, contact)
    assert.NoError(t, err)
}

Best practices and optimization

Remember to implement rate limiting to play nice with RD Station's API:

time.Sleep(time.Second / 10) // Max 10 requests per second

And consider caching frequently accessed data to reduce API calls.

Conclusion

And there you have it! You've just built a solid RD Station API integration in Go. Pretty cool, right? Remember, this is just the beginning. There's a whole world of endpoints and features to explore in the RD Station API. So go forth and code, my friend!
