Integration Guide
This guide covers common integration patterns with Ultimate Multisite, including connecting to external services, building custom payment gateways, and handling webhooks.
CRM Integration
Sync customer data to your CRM when new customers sign up:
add_action('wu_customer_post_create', 'sync_customer_to_crm');
function sync_customer_to_crm($customer) {
$crm_api = new Your_CRM_API();
$crm_api->create_contact([
'email' => $customer->get_email(),
'name' => $customer->get_display_name(),
'signup_date' => $customer->get_date_registered(),
'plan' => $customer->get_membership()->get_plan()->get_name()
]);
// Store CRM ID for future reference
$customer->add_meta('crm_contact_id', $crm_api->get_last_contact_id());
}
Analytics Integration
Track key business events across the customer lifecycle:
add_action('wu_checkout_completed', 'track_conversion', 10, 3);
add_action('wu_membership_status_to_cancelled', 'track_churn');
add_action('wu_payment_failed', 'track_payment_failure');
function track_conversion($payment, $customer, $membership) {
// Google Analytics 4
gtag('event', 'purchase', [
'transaction_id' => $payment->get_id(),
'value' => $payment->get_total(),
'currency' => $payment->get_currency(),
'items' => [
[
'item_id' => $membership->get_plan()->get_id(),
'item_name' => $membership->get_plan()->get_name(),
'category' => 'subscription',
'quantity' => 1,
'price' => $payment->get_total()
]
]
]);
}
