Error Handling

Handle errors gracefully in your AccruPay integration.

Error Types​

Authentication Errors​

Occur when API credentials are invalid or expired.

sdk = new AccruPay({
  // ...
  onAuthError: () => {
    console.error('Authentication failed');
    // Re-authenticate or alert user
  },
});

GraphQL Errors​

Validation or business logic errors.

onGraphQLError: (errors) sn=> {
  errors.forEach(error => {
    console.error('Error:', error.message);
    console.error('Code:', error.extensions?.code);
  });
},

Network Errors​

Connection timeouts or network issues.

onNetworkError: (error) => {
  console.error('Network issue:', error.message);
  // Implement retry logic
},

Retry Strategies​

Implement exponential backoff for transient errors:

async function retryWithBackoff(fn, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await fn();
    } catch (error) {
      if (i === maxRetries - 1) throw error;
      await new Promise(resolve => setTimeout(resolve, Math.pow(2, i) * 1000));
    }
  }
}
