My payment module doesn’t redirect or return, can you fix it?

Yes. When Stripe, PayPal, Mollie or a bank module never redirects, or returns to a broken order-confirmation, the cause is usually a failing validateOrder() call, a missing IPN/webhook return URL, or an SSL / base-URL mismatch between the gateway config and the shop. We trace the full payment hook flow, fix the return handling, and place real test orders so confirmations and order status update correctly.
