Integrating Stripe with Phoenix
Integrating Stripe into a Phoenix application involves several steps:
1. Installing a Stripe Library:
Use a library like `stripex` or a custom wrapper. These libraries provide Elixir functions for interacting with the Stripe API.
2. Configuring Stripe Credentials:
Store your Stripe API keys securely in your Phoenix application’s configuration files (using environment variables is a common practice). These keys are used to authenticate your application with the Stripe API.
3. Implementing Payment Flows:
Use Stripe’s APIs to create charges, subscriptions, and other payment-related objects. You’ll need to handle the user interface for collecting payment information and securely transmitting it to Stripe.
4. Handling Webhooks:
Stripe uses webhooks to notify your application about events such as successful payments, failed payments, and subscription updates. Implement webhook handlers in your Phoenix application to respond to these events accordingly.
5. Testing:
Thoroughly test your Stripe integration in a test environment before deploying it to production. Stripe provides test API keys and tools for simulating various payment scenarios.
Common Use Cases
- E-commerce Websites: Processing payments for products and services sold online.
- Subscription Services: Managing recurring billing for subscription-based businesses.
- Marketplaces: Facilitating payments between buyers and sellers.
- Donation Platforms: Accepting donations from users.
