Books emoji Enhance Your Laravel Apps Without The Stress

You've built a great app, but now your users want more power.

Maybe they want their monthly reports to be sent to their accounting software. Perhaps they need to automatically create new tasks in their project management tool, or they want contact form submissions to be automatically sent to their CRM.

There’s no doubt that integrating with third-party APIs and adding these features to your app is a great way to add value for your users , but it can also be super daunting to get started…

In fact, I’d go as far as to say API integrations are one of the most complex and scary things I’ve faced in my entire developer career! There are just so many things you’ve got to know if you want your API integration to work properly and be robust, secure and easy to maintain.

If your client or boss uttering the words “we need it to integrate with XYZ’s API” gives you nightmares, you’re certainly not alone.

What’s more, once you’ve started building your integration, it’s difficult to know how to write automated tests for your code. After all, creating an API integration without writing tests is a surefire way to build an integration that has bugs and is difficult to maintain.

But even more frustrating is the fact it’s also just so damn hard to find reliable information you can trust .

Take a look online and you’ll come across a huge amount of info about APIs that’s either completely outdated or just plain wrong. If you’ve ever done any research yourself, you’ll know it’s often near impossible to know what’s still relevant, or exactly how some of the concepts you’re learning are supposed to fit into your application.

Theory is great - but what you really need is actionable information from someone who knows the subject inside out…

And that’s exactly what I’m offering you today . It’s the comprehensive API manual I wish I had when I started out as a developer. One you can trust and will want to refer back to again and again.

Introducing Consuming APIs in Laravel, your complete guide to confidently building robust and powerful API integrations in your Laravel projects to add cool new features.

Whether you’re an experienced pro or just starting out in your developer career, it includes all the information you need to consume APIs directly from your Laravel application using maintainable, testable, and extensible code.

Inside, you’ll get instant access to over 440-pages of detailed yet easy-to-digest information with tons of real-world code examples you can start applying to your projects straight away.

Finally you can easily integrate third-party APIs with your Laravel project and feel confident in doing so!

Books emoji What's Covered in the Book?

The book aims to help you build powerful API integrations that are testable, maintainable, and easy to understand .

I'll show you the way I've built integrations for many projects that help my clients and their users, including specific code examples that give context as to exactly where, why, and how you’d use something in your Laravel app… Something I’ve found to be sorely lacking in many other books and tutorials I’ve read on the subject.

We'll cover techniques that we can use to improve the quality of API integration code .

We'll look at how we can use these techniques to integrate with real-world APIs using Saloon. We'll cover how to write tests for your API integrations, how to handle rate limits, and how to deal with errors .

When I started writing the book, one of my main aims was to really hone in on the areas that developers often find particularly confusing. For example, I’ve included a whole chapter on OAuth , which is a complex topic that people are often scared of going anywhere near, so I finally wanted to make it super understandable and less nightmarish! It contains diagrams and step-by-step instructions on how each “OAuth flow” works.

I’ve also added a full guide on how you can use Saloon in your Laravel applications to interact with an OAuth API . I’m really hoping that this section makes developers less scared of OAuth and encourages them to feel more confident and comfortable using it.

There’s also a dedicated section on securely handling webhooks sent from third-party APIs back to your application. I’ve worked on many projects where the developers haven’t written secure code for handling the webhooks, which has meant that there have been security vulnerabilities in the systems that could be exploited. Using code examples, I’ll show you exactly how to securely handle webhooks and make your API integration more robust and bulletproof.

In my experience, it’s information like this that is pure gold when it comes to becoming more competent and confident with handling APIs.

Throughout, I’ve really tried hard to break down a lot of the barriers and make everything super simple for you to dive right in with confidence and make your Laravel projects even more awesome!

Cowboy emoji Learn How to Consume APIs Using Saloon

We'll be covering how to consume APIs using Saloon v3, an awesome PHP package built by Sam Carré that has over 500k downloads!

Saloon provides a simple, fluent, and object-oriented approach for consuming APIs, making it easy for you to build API integrations without having to worry about the underlying implementation.

Inside, we'll take a look at what Saloon is, the benefits of using it, and alternative approaches that you may want to use. We'll then step through and reveal exactly how you can confidently install and use Saloon in your Laravel applications.
