Third-party API integration for WordPress & WooCommerce

Your site rarely lives alone. I connect WordPress and WooCommerce to the tools your business already runs — from accounting and ERP to e-signature, CRM, payments, and video — so data flows automatically instead of being re-keyed by hand.

wordpress-api-integration.php
// OAuth 2.0 token refresh, handled quietly by cron
wp_schedule_event( ‘wv_refresh_token’ );

// webhook back from Adobe Sign → order status
if ( $event === ‘AGREEMENT_SIGNED’ ) $order->payment_complete();

01 — The problem I solve

Where plugins run out

Manually copying orders into your accounting system, chasing signed agreements, or re-entering customer data into your CRM is slow and error-prone. A proper API integration removes the manual step entirely and keeps both systems in sync.
