01
What the webview breaks
Sandboxed cookies, missing Apple Pay / Google Pay, blocked pop-ups, and downloads that never start. A Gumroad or Shopify checkout that works in Chrome can fail in Instagram with no error the creator sees.
Adfluence is tested on devices in Instagram and TikTok webviews. Card forms, wallets when supported, and file delivery on the success page are the contract.
02
Apple Pay and Google Pay
They appear above the card form when Stripe and the device allow them. They will not appear on every iPhone in every webview version. Cards remain the fallback. India UPI is Razorpay, not Apple Pay.
03
Files in the webview
Delivery on the confirmation page matters more here than in desktop Chrome. If the only copy is email, the buyer is still inside Instagram, the mail app is not, and the refund clock starts.
