Hostinger Horizons has a built-in Online Store<\/a> that handles one-time payments automatically, so you don’t need to set up Stripe yourself.<\/p>To handle it manually instead, create a product for each item in Stripe and set a one-time payment pricing model to process single transactions.<\/p>
Then, note each product’s price ID and share it with Hostinger Horizons so it updates the payment process for each item. Here’s an example prompt:<\/p>
I want to set up Stripe payments for the following products. Here are their price IDs:\nprice_abc123... for \"Product 1\"\nprice_xyz789... for \"Product 2\"<\/pre>Donations and pay-what-you-want<\/strong><\/h3>A pay-what-you-want model lets users choose how much to donate, which suits creators, nonprofits, and other donation-based web apps.<\/p>
In Stripe, go to Payment Links → Create payment link<\/strong>, then select Customers choose what to pay<\/strong> as the payment type. Configure the other settings and click Create link<\/strong>.<\/p>Then, copy the generated link and share it with Hostinger Horizons. To add a donation button, use a prompt like this:<\/p>
I want to add a Support Us button that lets users contribute any amount. Link it to [the Stripe donation link].<\/pre>Security best practices when using Stripe on your web app<\/strong><\/h2>When integrating Stripe into your web app, follow these tips to minimize vulnerabilities:<\/p>
\n- Never expose secret keys in frontend code<\/strong>. Secret keys provide full access to your Stripe account, so always store them as server-side environment variables, as shown in step 6.<\/li>\n\n\n\n
- Validate webhook signatures server-side<\/strong>. Stripe includes a signature with each webhook event to prove it’s genuine, so use your STRIPE_WEBHOOK_SECRET<\/strong> to verify it before processing any event.<\/li>\n\n\n\n
- Use HTTPS to encrypt all data between users and your app<\/strong>. Hostinger provides free SSL for your web app, and Stripe’s checkout page is served over HTTPS by default.<\/li>\n\n\n\n
- Keep test and live environments separate<\/strong>. When moving to production, switch to live mode keys, update webhook endpoints to production URLs, and keep test data away from real transactions.<\/li>\n<\/ul>
Troubleshooting Stripe integration issues<\/strong><\/h2>Even with a proper setup, you may run into issues. Here are the most common ones and how to fix them:<\/p>
Invalid price ID or API keys<\/strong><\/h3>This happens when the keys in your project don’t match those in your Stripe dashboard.<\/p>
