Step by Step Guide to Building a Webflow API Integration in PHP

Introduction

Hey there, fellow developer! Ready to dive into the world of Webflow API integration? You're in for a treat. We'll be using the expertlead/webflow-php-sdk package to make our lives easier. This nifty tool will help us interact with Webflow's API like a pro. Let's get started!

Prerequisites

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

• A PHP environment up and running
• Composer installed (trust me, it's a lifesaver)
• Your Webflow API key handy

Got all that? Great! Let's move on.

Installation

First things first, let's get our SDK installed. Open up your terminal and run:

composer require expertlead/webflow-php-sdk

Easy peasy, right?

Setting up the Webflow Client

Now, let's initialize our Webflow client. It's as simple as:

use Webflow\WebflowClient;

$client = new WebflowClient('YOUR_API_KEY');

Replace 'YOUR_API_KEY' with your actual API key, and you're good to go!

Basic Operations

Fetching Sites

Want to get a list of your sites? Here's how:

$sites = $client->sites();
foreach ($sites as $site) {
    echo $site->getName() . "\n";
}

Retrieving Collections

Need to grab your collections? No problem:

$collections = $client->collections('SITE_ID');
foreach ($collections as $collection) {
    echo $collection->getName() . "\n";
}

Getting Items from a Collection

Time to fetch some items:

$items = $client->items('COLLECTION_ID');
foreach ($items as $item) {
    echo $item->getName() . "\n";
}

Creating and Updating Content

Adding New Items

Let's add a new item to a collection:

$newItem = $client->createItem('COLLECTION_ID', [
    'name' => 'New Item',
    'slug' => 'new-item',
    // Add other fields as needed
]);

Updating Existing Items

Need to update an item? We've got you covered:

$updatedItem = $client->updateItem('COLLECTION_ID', 'ITEM_ID', [
    'name' => 'Updated Item Name',
    // Update other fields as needed
]);

Advanced Operations

Working with Custom Fields

Custom fields are a breeze:

$newItem = $client->createItem('COLLECTION_ID', [
    'name' => 'Custom Item',
    'custom-field' => 'Custom Value',
]);

Handling Pagination

Don't forget about pagination:

$offset = 0;
$limit = 100;

do {
    $items = $client->items('COLLECTION_ID', $offset, $limit);
    // Process items
    $offset += $limit;
} while (count($items) == $limit);

Error Handling

Always be prepared for errors:

try {
    $item = $client->item('COLLECTION_ID', 'NON_EXISTENT_ITEM_ID');
} catch (\Exception $e) {
    echo "Oops! " . $e->getMessage();
}

Best Practices

• Keep an eye on rate limits. Webflow's API has limits, so be nice!
• Consider caching responses to reduce API calls and speed up your app.

Example Project: Content Sync Script

Here's a quick example to get your creative juices flowing:

$sourceCollection = 'SOURCE_COLLECTION_ID';
$targetCollection = 'TARGET_COLLECTION_ID';

$sourceItems = $client->items($sourceCollection);

foreach ($sourceItems as $item) {
    $existingItem = $client->items($targetCollection, ['slug' => $item->getSlug()]);
    
    if ($existingItem) {
        $client->updateItem($targetCollection, $existingItem->getId(), $item->toArray());
    } else {
        $client->createItem($targetCollection, $item->toArray());
    }
}

This script syncs content between two collections. Cool, huh?

Conclusion

And there you have it! You're now equipped to build awesome Webflow API integrations with PHP. Remember, practice makes perfect, so don't be afraid to experiment and push the boundaries.
