The Management API provides complete control over your PayNow store resources. Use it to programmatically manage products, orders, customers, analytics, and more from your server-side applications.

​
Authentication

The Management API requires authentication using an API key. You can generate an API key from your store’s dashboard.
Never expose your API key in client-side code. API keys grant full access to your store and should only be used in secure server environments.

​
Client Setup

Initialize the management client with your store ID and API key: 
import { createManagementClient } from '@paynow-gg/typescript-sdk';

const client = createManagementClient(
  'your-store-id',
  'your-api-key'
);

​
API Structure

Operations are organized by resource type. Each resource is accessed as a property on the client:
  • client.products - Product management
  • client.orders - Order management and refunds
  • client.customers - Customer management
  • client.payments - Payment information
  • client.coupons - Coupon management
  • client.sales - Sales and discounts
  • client.subscriptions - Subscription management
  • client.giftcards - Gift card management
  • client.webhooks - Webhook subscriptions
  • client.gameServers - Game server connections
  • client.delivery - Delivery item management
  • client.customVariables - Custom product variables
  • client.tags - Product tags
  • And more…

​
Response Format

All API methods return an Axios response object: 
const response = await client.products.getProducts();

console.log(response.status); // 200
console.log(response.data); // Array of products
console.log(response.headers); // Response headers

​
Error Handling

The SDK uses standard Axios error handling. Use the isPayNowError helper to check for API errors: 
import { createManagementClient, isPayNowError } from '@paynow-gg/typescript-sdk';

try {
  const response = await client.products.getProduct({
    path: { productId: 'invalid-id' }
  });
} catch (error) {
  if (isPayNowError(error)) {
    console.error('PayNow Error:', error.response?.data);
  } else {
    console.error('Unexpected error:', error);
  }
}

​
Pagination

Many list endpoints support cursor-based pagination using after, before, limit, and asc parameters: 
// Get first page
const firstPage = await client.products.getProducts({
  params: { limit: 50 }
});

// Get next page
const lastId = firstPage.data[firstPage.data.length - 1].id;
const nextPage = await client.products.getProducts({
  params: { limit: 50, after: lastId }
});

​
Rate Limits

The Management API is rate-limited to ensure system stability. Rate limit information is included in response headers:
  • X-RateLimit-Limit - Maximum requests per window
  • X-RateLimit-Remaining - Remaining requests in current window
  • X-RateLimit-Reset - Time when the rate limit resets
