Install the Necessary Libraries
- To interact with Klaviyo's API using PHP, you'll first need to ensure you have the necessary libraries. One commonly used library for making HTTP requests in PHP is Guzzle. Install it using Composer:
composer require guzzlehttp/guzzle
Obtain Klaviyo API Key
- Klaviyo requires an API key for authentication. Ensure you have your private API key ready, as you'll need it to make requests to the API endpoints.
Sending an Email through Klaviyo
- To send an email, you will generally need to interact with one of Klaviyo's key functionalities, like Lists or Send Campaign APIs. Below is a general example of how you can send an email using the Klaviyo API:
<?php
require 'vendor/autoload.php';
use GuzzleHttp\Client;
function sendEmail($apiKey, $listId, $email, $additionalParameters = []) {
$client = new Client([
'base_uri' => 'https://a.klaviyo.com/api/',
'timeout' => 2.0,
]);
$response = $client->request('POST', 'v2/list/'.$listId.'/members', [
'json' => array_merge([
'api_key' => $apiKey,
'email' => $email,
], $additionalParameters)
]);
if ($response->getStatusCode() == 200) {
echo "Email has been successfully sent.";
} else {
echo "Failed to send email.";
}
}
$apiKey = 'YOUR_KLAVIYO_API_KEY';
$listId = 'YOUR_LIST_ID';
$email = 'recipient@example.com';
sendEmail($apiKey, $listId, $email);
?>
Handling Response and Errors
- Ensure that you handle the response of the API call effectively. Handle exceptions that Guzzle might throw if the HTTP request fails.
<?php
function sendEmail($apiKey, $listId, $email, $additionalParameters = []) {
$client = new Client([
'base_uri' => 'https://a.klaviyo.com/api/',
'timeout' => 2.0,
]);
try {
$response = $client->request('POST', 'v2/list/'.$listId.'/members', [
'json' => array_merge([
'api_key' => $apiKey,
'email' => $email,
], $additionalParameters)
]);
if ($response->getStatusCode() == 200) {
echo "Email has been successfully sent.";
} else {
echo "Failed to send email.";
}
} catch (\GuzzleHttp\Exception\RequestException $e) {
if ($e->hasResponse()) {
echo "Error: " . $e->getResponse()->getBody();
} else {
echo "Request error: " . $e->getMessage();
}
}
}
?>
Create Segments or Lists if Necessary
- If your marketing strategy involves sending emails to specific segments or lists, you may need to create or manage these lists through the API.
Verify Data Format
- Ensure that the data you send to Klaviyo is in the correct format. Double-check field names, types, and required fields specified in the Klaviyo API documentation.
Testing and Deployment
- Before moving to production, thoroughly test your integration to ensure it handles all potential edge cases and conforms with Klaviyo's API usage guidelines.
Security Considerations
- Keep your API key secure. Never expose it publicly and manage it through environment variables or a secure vault solution.
