Pdfboxi.in Advanced Admin Notes ============================ New sections: Branding & Theme, Pages & Footer, Payment Gateways, Offers, Email & Reminders, Add Tools. Public settings endpoint exposes only public branding/content and never exposes payment secrets. Razorpay config is runtime editable by admin and used for order creation/verification. ZapUPI checkout is integrated server-side: create order, same-tab payment redirect, webhook receiver and server-side order-status confirmation. Webhook URL: https://YOUR-DOMAIN/api/zapupi-webhook.php. Configure this exact URL in ZapUPI dashboard. Do not use test environment payments for live subscription activation. Cron endpoint is protected by a long random secret. Prefer cPanel CLI Cron. MySQL schema: pdfboxi_mysql_schema.sql. Import into an empty DB in phpMyAdmin, then set db.driver=mysql and credentials in private/config.php. Tool registry adds custom tool page links; the actual PDF/image processing logic must exist in the linked page.
