The Client ID, Secret Key, and Webhook are already in place and verified, yet during order checkout the Pay Now button does nothing when clicked - no redirect, no error, just silence.

    I run an online platform where clients create and manage customer-engagement SMS campaigns. I now need PayPal Checkout woven seamlessly into the site so users can pay for their messaging credits without ever leaving the flow of campaign creation. Here is what I’m after: • Add the latest PayPal Smart Buttons to the purchase page that sells SMS credit bundles. • Support both Sandbox and Live modes so I can test before going public. • Once a transaction is authorised, instantly credit the buyer’s account and trigger our existing confirmation email/SMS. • Capture and store PayPal transaction IDs in my MySQL database; I’ll provide the table schema. • Make sure the integration works smoothly on desktop and mobile, and that errors (cancellation...

    I’m unable to send money from my PayPal personal account and need an experienced PayPal troubleshooter to pinpoint and resolve whatever is blocking outgoing payments. You’ll walk me through the exact settings, verification checks or security flags that typically stop a transfer, guide me in real time (screen-share or detailed step-by-step notes—whichever you prefer), and confirm the account can successfully send a small test payment before we wrap up. Deliverables: • Clear explanation of the root cause and how you found it • Step-by-step actions I should take (so I can replicate the fix if it happens again) • Confirmation screenshot or transaction ID showing a completed test payment Once the test payment is sent without errors, the job is com...

    My Shopify store is ready to launch, but PayPal still isn’t connected. I already hold a PayPal Business account; I simply haven’t begun the integration inside Shopify yet. I need you to: • Add PayPal as the primary payment processor, using the standard Shopify-PayPal flow (Express Checkout), enable test transactions, and confirm funds settle correctly. • Walk me through any settings that must be adjusted in PayPal or Shopify so refunds, multi-currency, and order status updates work automatically. Once PayPal is live and tested, I’ll move straight to phase two—fine-tuning shipping rules (zone rates, carrier-calculated options, or bespoke price tiers, depending on what you recommend). If you’re comfortable handling that as well, let me know so we can...
