how to integrate stripe with multiple currency for payment processing in typescript

To integrate Stripe with multiple currency for payment processing, follow the steps below:

1. Create a Stripe account and obtain the API keys for both the live and test environments.

2. Install the stripe package in your TypeScript project using the following command:

   index.ts
   npm install stripe
   19 chars
   2 lines

3. Import the Stripe library and initialize it with your API key:

   index.ts
   import Stripe from "stripe";
   
   const stripe = new Stripe("API_KEY", {
     apiVersion: "2020-08-27"
   });
   100 chars
   6 lines

4. Create a payment intent to charge a customer in a specific currency using the following code:

   index.ts
   const paymentIntent = await stripe.paymentIntents.create({
     amount: 1000,
     currency: "usd",
     payment_method_types: ["card"],
     payment_method_options: {
       card: {
         installments: null
       }
     }
   });

   11 lines

   Replace amount and currency with the desired amount and currency code. You can find a list of supported currencies on Stripe's documentation.

5. After the payment intent is created, you can confirm the payment by providing a payment method:

   index.ts
   const paymentIntent = await stripe.paymentIntents.confirm(
     "PAYMENT_INTENT_ID",
     {
       payment_method: "pm_card_visa"
     }
   );

   7 lines

   Replace PAYMENT_INTENT_ID with the ID of the payment intent generated in step 4. Replace pm_card_visa with the ID of the payment method used for the transaction.

6. You can also retrieve a list of supported currencies from the API using the following code:

   index.ts
   const currencies = await stripe.currencies.list({
     limit: 100
   });
   67 chars
   4 lines

   This will return an array of currencies supported by Stripe.

That's it! With these steps, you can integrate Stripe with multiple currencies for payment processing in your TypeScript project.
