How to Call an External API Using Laravel 11 | 100% Work

How to Call an External API Using Laravel. In this tutorial, we’ll create a Laravel application that interacts with an external API to fetch and display a paginated list of posts. We’ll also implement buttons that trigger delete and update calls to the external API. Calling external APIs allow us to integrate with any third parties that exposes their functionality accordingly.

Note the data will be fetched externally but the updates and deletes will be simulated since the test API (jsonplaceholder.typicode.com) we’re using is read-only.

We will be using the Laravel built-in Http facade to send the API calls. While you could also use Guzzle to do this, using the Http facade is the recommended way to go about it. Using the Http facade offers a concise syntax that is in line with Laravel and adds more features like mocking HTTP responses for automated testing. Read Laravel Documantation

Let’s get started! How to Call an External API Using Laravel 11 | 100% Working

How to Call an External API Using Laravel 11

Step 1: Set Up Your Laravel Project

Create a new Laravel project or use an existing one:

composer create-project laravel/laravel example-app

Step 2: Create Controller

Create a controller by running:

php artisan make:controller PostController

Step 3: Add Controller Code

Now let’s add code to the PostController to implement methods to show, update, and delete posts by triggering calls to the external posts API:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Http;

class PostController extends Controller
{
    public function index()
    {
        $response = Http::get('https://jsonplaceholder.typicode.com/posts');
        $posts = $response->json();

        return view('posts.index', ['posts' => $posts]);
    }

    public function edit($id)
    {
        $response = Http::get('https://jsonplaceholder.typicode.com/posts/' . $id);
        $post = $response->json();

        return view('posts.edit', ['post' => $post]);
    }

    public function update(Request $request, $id)
    {
        // Simulates update logic for a real application (not supported by this API)
        $response = Http::put('https://jsonplaceholder.typicode.com/posts/' . $id, [
            'title' => $request->input('title'),
            'body' => $request->input('body'),
        ]);

        // Simulated response for successful or failed update
        if ($response->successful()) {
            return redirect()->route('posts.index')->with('success', 'Post updated successfully!');
        } else {
            return redirect()->route('posts.index')->with('error', 'Failed to update post. Please try again.');
        }
    }

    public function destroy($id)
    {
        // Simulates deletion logic for a real application (not supported by this API)
        $response = Http::delete('https://jsonplaceholder.typicode.com/posts/' . $id);

        // Simulated response for successful or failed deletion
        if ($response->successful()) {
            return redirect()->route('posts.index')->with('success', 'Post deleted successfully!');
        } else {
            return redirect()->route('posts.index')->with('error', 'Failed to delete post. Please try again.');
        }
    }
}

Step 4: Define Routes

Define routes for post actions in routes/web.php as follows:

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\PostController;

Route::get('/', [PostController::class, 'index'])->name('posts.index');
Route::get('/posts/{id}/edit', [PostController::class, 'edit'])->name('posts.edit');
Route::put('/posts/{id}', [PostController::class, 'update'])->name('posts.update');
Route::delete('/posts/{id}', [PostController::class, 'destroy'])->name('posts.destroy');

Step 5: Create a Base Layout

Let’s use a simple layout that is based on bootstrap 5 that can show any content along with any success or error message that may occur. Create a file resources/views/layouts/app.blade.php and add:

<!DOCTYPE html>
<html lang="en">
<head>
    <!-- Other meta tags -->
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0/dist/css/bootstrap.min.css" rel="stylesheet">
    <link href="https://cdn.jsdelivr.net/npm/bootstrap-icons/font/bootstrap-icons.css" rel="stylesheet">
    <!-- Other CSS -->
</head>
<body>

    <div class="container mt-4">

    <!-- Display success or error messages -->
    @if (session('success'))
        <div class="alert alert-success">
            {{ session('success') }}
        </div>
    @endif

    @if (session('error'))
        <div class="alert alert-danger">
            {{ session('error') }}
        </div>
    @endif

    @yield('content')

    </div>
</body>
</html>

Step 6: Create a View to Show Posts From API

Now let’s create the Blade view which displays the list of posts. Create a file at resources/views/posts/index.blade.php and add the following code:

@extends('layouts.app')

@section('content')
    <div class="container mt-4">
        <h1>Posts</h1>
        <div class="table-responsive mt-3">
            <table class="table table-striped">
                <thead>
                <tr>
                    <th>Title</th>
                    <th>Body</th>
                    <th>Actions</th>
                </tr>
                </thead>
                <tbody>
                @foreach($posts as $post)
                    <tr>
                        <td>{{ $post['title'] }}</td>
                        <td>{{ $post['body'] }}</td>
                        <td>
                            <div class="d-flex">
                                <a href="{{ route('posts.edit', $post['id']) }}" class="btn btn-sm btn-primary me-2">
                                    <i class="bi bi-pencil"></i>
                                </a>
                                <form action="{{ route('posts.destroy', $post['id']) }}" method="POST">
                                    @csrf
                                    @method('DELETE')
                                    <button type="submit" class="btn btn-sm btn-danger">
                                        <i class="bi bi-trash"></i>
                                    </button>
                                </form>
                            </div>
                        </td>
                    </tr>
                @endforeach
                </tbody>
            </table>
        </div>
    </div>
@endsection

Step 7: Create Blade View for Edit Post From API

Create a Blade view for the post edit form in resources/views/posts/edit.blade.php. Include the form with populated data, the correct action/route, and @csrf:

@extends('layouts.app')

@section('content')
    <div class="container mt-4">
        <h1>Edit Post</h1>
        <form action="{{ route('posts.update', $post['id']) }}" method="POST">
            @csrf
            @method('PUT')
            <div class="mb-3">
                <label for="title" class="form-label">Title</label>
                <input type="text" class="form-control" id="title" name="title" value="{{ $post['title'] }}">
            </div>
            <div class="mb-3">
                <label for="body" class="form-label">Body</label>
                <textarea class="form-control" id="body" name="body">{{ $post['body'] }}</textarea>
            </div>
            <button type="submit" class="btn btn-primary">Update</button>
        </form>
    </div>
@endsection

Step 8: Test the Application

Run your Laravel server using php artisan serve and navigate to http://localhost:8000 in your browser. You’ll have a paginated list of posts with functional delete and edit buttons, and an edit form ready for updates.
