* Use the `wp_remote_post` function or your chosen HTTP client to send data to the Mailchimp API.
* Here’s an example of subscribing a user to a list using `wp_remote_post`:
php
$email,
‘status’ => ‘subscribed’,
]);
$args = [
‘headers’ => [
‘Authorization’ => ‘Basic ‘ . $auth,
‘Content-Type’ => ‘application/json’,
],
‘body’ => $body,
‘method’ => ‘POST’,
‘data_format’ => ‘body’,
];
$response = wp_remote_post($url, $args);
if (is_wp_error($response)) {
error_log(‘Mailchimp API Error: ‘ . $response->get_error_message());
return false;
} else {
$body = json_decode(wp_remote_retrieve_body($response));
if (isset($body->status) && $body->status >= 400) {
error_log(‘Mailchimp API Error: ‘ . $body->detail); //Detailed error message from Mailchimp
return false;
} else {
return true;
}
}
}
// Example usage:
$email = ‘[email protected]’;
$list_id = ‘YOUR_LIST_ID’; // Replace with your Mailchimp list ID
$api_key = ‘YOUR_API_KEY’; // Replace with your Mailchimp API key
if (subscribe_user_to_mailchimp($email, $list_id, $api_key)) {
echo ‘User subscribed successfully!’;
} else {
echo ‘Failed to subscribe user.’;
}
?>
* **Step 4: Integrate with Your Forms:**
* Modify your website’s forms (e.g., contact form, registration form) to call the `subscribe_user_to_mailchimp` function when a new user submits their email address.
* **Step 5: Error Handling and Logging:**
* Implement proper error handling to catch any issues with the API request.
* Log errors to help you debug and troubleshoot problems.
### 2. Integrating with a Social Media Platform (Facebook Example)

$body = json_decode(wp_remote_retrieve_body($response));
if (isset($body->error)) {
error_log(‘Facebook API Error: ‘ . $body->error->message);
return false;
} else {
return true;
}
}
}
// Example Usage (Replace with your actual values):
$page_id = ‘YOUR_FACEBOOK_PAGE_ID’;
$access_token = ‘YOUR_PAGE_ACCESS_TOKEN’;
$message = ‘Hello from my WordPress site!’;
if (post_to_facebook_page($page_id, $access_token, $message)) {
echo ‘Successfully posted to Facebook!’;
} else {
echo ‘Failed to post to Facebook.’;
}
?>
* **Step 5: Handle Permissions and Authentication:**
