The cart is already filled, the discount is already applied, and all the user needs to do is confirm payment. For a broader look at deep linking strategies for online stores, see <a href=\"https:\/\/tolinku.com\/blog\/deep-linking-ecommerce-apps\/\">Deep Linking for E-commerce Apps<\/a>.<\/p>\n\n\n\n<p>This is the most aggressive deep linking strategy for e-commerce.

Security matters:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Prevent Unauthorized Purchases<\/h3>\n\n\n\n<p>The deep link should never auto-complete the purchase. It should:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Pre-fill the cart<\/li>\n<li>Apply any discounts<\/li>\n<li>Show the checkout summary<\/li>\n<li><strong>Wait for the user to confirm payment<\/strong><\/li>\n<\/ol>\n\n\n\n<p>Never auto-charge based on a URL. The user must explicitly confirm.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Validate Promo Codes Server-Side<\/h3>\n\n\n\n<p>Even if the deep link includes a promo code, validate it server-side at checkout:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Is the code still active?<\/li>\n<li>Is it applicable to these products?<\/li>\n<li>Has this user already used it?<\/li>\n<li>Has the code exceeded its usage limit?<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Rate Limit Checkout Creation<\/h3>\n\n\n\n<p>If someone scripts rapid checkout link requests, they could create spam orders or exploit promo codes. Rate limit checkout creation per user\/device.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Authenticate Before Checkout<\/h3>\n\n\n\n<p>For high-value orders or first-time users, require authentication before showing the checkout screen:<\/p>\n\n\n\n<pre><code class=\"language-javascript\">if (user.isLoggedIn === false) {\n  \/\/ Store the checkout deep link data\n  pendingCheckout.save(checkoutData);\n  \/\/ Navigate to login\n  navigation.navigate(&#39;Login&#39;, { redirectTo: &#39;Checkout&#39; });\n} else {\n  navigation.navigate(&#39;Checkout&#39;);\n}\n<\/code><\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Measuring Checkout Deep Link Performance<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table>\n<thead>\n<tr>\n<th>Metric<\/th>\n<th>Formula<\/th>\n<th>Target<\/th>\n<\/tr>\n<\/thead>\n<tbody><tr>\n<td>Checkout completion rate<\/td>\n<td>Purchases \/ Checkout opens<\/td>\n<td>50-70%<\/td>\n<\/tr>\n<tr>\n<td>Time to purchase<\/td>\n<td>Seconds from link tap to payment<\/td>\n<td>&lt; 30 seconds<\/td>\n<\/tr>\n<tr>\n<td>Promo redemption rate<\/td>\n<td>Promo-applied purchases \/ Total checkout opens<\/td>\n<td>60-80%<\/td>\n<\/tr>\n<tr>\n<td>Average order value<\/td>\n<td>Revenue \/ Orders from checkout links<\/td>\n<td>Compare to organic<\/td>\n<\/tr>\n<tr>\n<td>Return rate<\/td>\n<td>Returns \/ Orders from checkout links<\/td>\n<td>Should match organic<\/td>\n<\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n<p>If the return rate for checkout deep link orders is significantly higher than organic orders, it may indicate users are buying impulsively without enough consideration.
