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

Sep 14, 2024 • 6 minute read

Introduction

Hey there, fellow Go enthusiast! Ready to dive into the world of Thryv API integration? You're in for a treat. We're going to walk through building a robust integration that'll have you pulling customer data, managing appointments, and handling invoices like a pro. Let's get cracking!

Prerequisites

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

Go installed (I know, obvious, right?)
Thryv API credentials (if you don't have these, time to sweet-talk your Thryv rep)
A cup of coffee (or your preferred coding fuel)

As for Go packages, we'll be using:

oauth2 for authentication
resty for making HTTP requests (trust me, it'll make your life easier)

Setting up the project

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

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

Easy peasy, right? Now we've got a clean slate to work with.

Authentication

Alright, time to tackle the OAuth 2.0 flow. Don't worry, it's not as scary as it sounds:

import (
    "golang.org/x/oauth2"
)

func getToken() (*oauth2.Token, error) {
    // Your OAuth magic here
}

Pro tip: Store those access tokens securely and implement a refresh mechanism. Future you will thank present you.

Making API requests

Let's create a basic API client. We'll use resty to keep things clean:

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

type ThryvClient struct {
    client *resty.Client
}

func NewThryvClient(token string) *ThryvClient {
    return &ThryvClient{
        client: resty.New().SetAuthToken(token),
    }
}

Don't forget to handle rate limiting and retries. The Thryv API can be a bit temperamental sometimes.

Implementing key Thryv API endpoints

Now for the fun part! Let's implement some endpoints:

func (c *ThryvClient) GetCustomers() ([]Customer, error) {
    // API call to get customers
}

func (c *ThryvClient) CreateAppointment(appointment Appointment) error {
    // API call to create an appointment
}

func (c *ThryvClient) GetInvoices() ([]Invoice, error) {
    // API call to get invoices
}

Feel free to add more endpoints as needed. Sky's the limit!

Error handling and logging

Don't let those pesky errors catch you off guard:

import "github.com/sirupsen/logrus"

func (c *ThryvClient) handleError(err error) {
    logrus.WithError(err).Error("API request failed")
    // More error handling logic
}

Trust me, your future self will appreciate good logging when debugging at 2 AM.

Testing the integration

Time to make sure this baby purrs like a kitten:

func TestGetCustomers(t *testing.T) {
    // Your test logic here
}

Don't skimp on the tests. They're your safety net when refactoring or adding features.

Best practices and optimization

Want to really impress? Implement some caching:

import "github.com/patrickmn/go-cache"

var customerCache = cache.New(5*time.Minute, 10*time.Minute)

And don't forget about concurrent requests to speed things up!

Conclusion

And there you have it! You've just built a Thryv API integration that would make any Gopher proud. Remember, this is just the beginning. Keep exploring the API, add more features, and most importantly, have fun with it!

Now go forth and integrate! And if you run into any snags, remember: Stack Overflow is your friend. Happy coding!
