2. Development Environment

Make sure you have the following installed:

PHP installed
A code editor (VS Code, Sublime, etc.)
Command line interface access

Implementation

Step 1: Install HTTP Client

We'll use curl to make HTTP requests.

bash

# PHP cURL extension required

Step 2: API Implementation

Now let's make a request to the Facebook API using PHP. Replace YOUR_API_KEY with your actual API key.

php

<?php
$apiKey = "YOUR_API_KEY";
$url = "https://api.sociavault.com/facebook/post/transcript?url=https%3A%2F%2Fwww.facebook.com%2Freel%2F1535656380759655";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, [
    "x-api-key: $apiKey",
    "Content-Type: application/json"
]);

$response = curl_exec($ch);
curl_close($ch);

echo $response;
?>

Testing Your Code

API Parameters

Best Practices

Error Handling

Implement comprehensive error handling and retry logic for failed requests. Log errors properly for debugging.

Caching

Cache responses when possible to reduce API calls and improve performance. Consider data freshness requirements.

Security

Never expose your API key in client-side code. Use environment variables and secure key management practices.

Troubleshooting

401

Unauthorized

Check your API key is correct and properly formatted in the x-api-key header.

402

Payment Required

You ran out of credits and need to buy more.

404

Not Found

The resource (user, video, etc.) might not exist or be private.

429

Too Many Requests

You have exceeded your rate limit. Slow down your requests.
