10 solutionsAsynchronous Processing with Limits
Use asynchronous programming patterns with explicit controls on the number of concurrent tasks.
Limit Concurrent Connections
Configure your application to limit the number of active connections to the API at any given time.
Use a Retry Queue with Delays
Queue failed requests and process them with appropriate delays to avoid overwhelming the API.
Implement Exponential Backoff
When a rate limit is hit, wait for an increasing amount of time before retrying the request.
Utilize Bulk Endpoints
Check if the API offers endpoints for retrieving or manipulating multiple resources at once.
Batch API Requests
If the API supports it, group multiple data fetches or updates into single requests.
Request Limit Increase
Contact the API provider to inquire about increasing your rate limit if your usage is legitimate.
Optimize API Call Frequency
Review your application's logic to reduce unnecessary or redundant API calls.
Implement Client-Side Rate Limiting
Add logic to your application to control the rate at which it sends requests to the API.
Perform a Clean Boot
Start your computer with a minimal set of startup programs and services to identify if any background software is causing the conflict.

Identified Causes
Incorrect Payment Details
75%The payment information entered, such as card number, expiry date, CVV, or billing address, may be incorrect or outdated. This is a common reason for payment failures.
Insufficient Funds or Credit Limit
60%The account associated with the payment method may not have sufficient funds available or may have reached its credit limit. This would cause the transaction to be declined.
Bank or Payment Processor Decline
55%The user's bank or the payment processor may have declined the transaction for various reasons, such as suspected fraud, security flags, or technical issues on their end.
Website/Platform Technical Glitch
30%The e-commerce website or payment gateway itself might be experiencing technical difficulties that are preventing payment processing. This is less common but possible.
