• Codes in the 5xx range indicate an error with our servers

​

Best Practices

1. Always check the response status
   • Verify both HTTP status code and response body
2. Implement proper error handling
   • Handle both expected and unexpected errors
   • Log errors for debugging
3. Retry mechanism
   • Implement exponential backoff for 5xx errors
   • Don’t retry on 4xx errors (except 429)
4. Rate limiting
   • Monitor rate limit headers
   • Implement rate limit handling

​

Example Error Handling

try {
  const response = await dexchangeApi.initiatePayment({
    amount: 1000,
    phone: '221700000000',
  });
} catch (error) {
  if (error.code === 'INVALID_PHONE') {
    // Handle invalid phone number
  } else if (error.code === 'INSUFFICIENT_FUNDS') {
    // Handle insufficient funds
  } else {
    // Handle other errors
  }
}
