    "updatedAt": "2026-03-01T10:00:00.000Z"
  }
}

Purchase Workflow

Create a payment intent

Initiate a purchase by creating a Stripe payment intent:

curl -X POST https://api.vaniykempire.com/payments/create-payment-intent \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..." \
  -d '{
    "contentId": "64def789abc123456"
  }'

Response:

{
  "clientSecret": "pi_3AbCdEfGhIjKlMnO_secret_pQrStUvWxYzAbCdEfGhIjKlMnO",
  "amount": 29.99
}

What happens:

The API validates the content exists and is published
Checks if you’ve already purchased this content
Creates a Stripe PaymentIntent for the content price
Creates a pending purchase record in MongoDB
Returns a clientSecret for completing payment

Users receive a 400 error if they attempt to purchase content they already own.

Complete payment with Stripe

Use the clientSecret with Stripe.js or Stripe Elements to collect payment:Frontend example (React with Stripe.js):

import { loadStripe } from '@stripe/stripe-js';
import { Elements, PaymentElement, useStripe, useElements } from '@stripe/react-stripe-js';

const stripePromise = loadStripe('pk_test_...');

function CheckoutForm({ clientSecret }) {
  const stripe = useStripe();
  const elements = useElements();

  const handleSubmit = async (e) => {
    e.preventDefault();

    if (!stripe || !elements) return;

    const { error, paymentIntent } = await stripe.confirmPayment({
      elements,
      confirmParams: {
        return_url: 'https://yourapp.com/payment-success',
      },
    });

    if (error) {
      console.error(error.message);
    } else if (paymentIntent.status === 'succeeded') {
      console.log('Payment successful!');
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <PaymentElement />
      <button type="submit" disabled={!stripe}>Pay</button>
    </form>
  );
}

function App({ clientSecret }) {
  return (
    <Elements stripe={stripePromise} options={{ clientSecret }}>
      <CheckoutForm clientSecret={clientSecret} />
    </Elements>
  );
}

Stripe handles all payment processing. When payment succeeds, Stripe sends a webhook to your API to complete the purchase.

Check payment status

Verify the payment status using the payment intent ID:

curl -X GET https://api.vaniykempire.com/payments/status/pi_3AbCdEfGhIjKlMnO \
  -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."

Response:

{
  "purchase": {
    "_id": "64xyz789abc456def",
    "user": "64abc123def456789",
    "content": {
      "_id": "64def789abc123456",
      "title": "Advanced JavaScript Patterns",
      "description": "Deep dive into modern JavaScript design patterns...",
      "type": "video",
      "thumbnailUrl": "https://res.cloudinary.com/vaniyk/..."
    },
    "amount": 29.99,
    "stripePaymentIntentId": "pi_3AbCdEfGhIjKlMnO",
    "status": "completed",
    "purchasedAt": "2026-03-03T14:30:00.000Z"
  }
}

Purchase statuses:

pending: Payment intent created, awaiting payment
completed: Payment successful, content available
failed: Payment failed
refunded: Purchase refunded by admin

Access Purchased Content

curl -X GET "https://api.vaniykempire.com/content/purchases?page=1&limit=10" \
  -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."

Response:

      "status": "completed",
      "purchasedAt": "2026-03-03T14:30:00.000Z"
    }
  ],
  "totalPages": 2,
  "currentPage": 1,
  "totalPurchases": 12
}

Access content file

Once purchased, retrieve the content with file URLs:

curl -X GET https://api.vaniykempire.com/content/64def789abc123456/access \
  -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."

Response:

{
  "content": {
    "_id": "64def789abc123456",
    "title": "Advanced JavaScript Patterns",
    "description": "Deep dive into modern JavaScript design patterns...",
    "type": "video",
    "category": "64abc123def456789",
    "price": 29.99,
    "fileUrl": "https://res.cloudinary.com/vaniyk/video/upload/v1/content/videos/abc123.mp4",
    "filePublicId": "content/videos/abc123",
    "thumbnailUrl": "https://res.cloudinary.com/vaniyk/image/upload/v1/content/thumbnails/xyz123.jpg",
    "duration": 3600,
    "fileSize": 524288000,
    "status": "published",
    "tags": ["javascript", "patterns", "advanced"],
    "createdBy": {
      "_id": "64abc789def123456",
      "name": "Admin User"
    },
    "createdAt": "2026-03-01T10:00:00.000Z",
    "updatedAt": "2026-03-01T10:00:00.000Z"
  }
}

This endpoint returns 403 Forbidden if you haven’t purchased the content.

Error Handling

Common error scenarios:

Status Code	Error	Description
400	Already purchased	User already owns this content
401	Unauthorized	Missing or invalid authentication token
403	Forbidden	Attempting to access unpurchased content
404	Not found	Content doesn’t exist or isn’t published
500	Server error	Internal error during payment processing

Example error response:

{
  "error": "You have already purchased this content"
}

Implementation Tips

Stripe Testing: Use Stripe test cards for development:

Success: 4242 4242 4242 4242
Decline: 4000 0000 0000 0002
Requires authentication: 4000 0025 0000 3155

Use any future expiration date and any 3-digit CVC.

Webhook Processing: The purchase status is updated asynchronously via webhooks. After payment confirmation:

Poll the /payments/status/:paymentIntentId endpoint
Wait for status to change from pending to completed
Then redirect to the content access page
