Our Forex API provides real-time and historical foreign exchange rate data, helping developers and businesses integrate currency information into their applications. However, like any API, occasional issues may arise, from authentication errors to unexpected response data. This guide will walk you through troubleshooting common problems to ensure seamless integration.
Common Issues and Solutions
1. Authentication Errors
One of the most common issues users face is authentication failure. If your API request is returning an “Invalid API Key” or “Unauthorized Access” error, try the following:
- Double-check that your API key is correctly copied and included in the request header or query parameters.
- Ensure your API key has not expired or been revoked.
- Verify that your account has the necessary permissions to access the requested data.
2. Rate Limits & Throttling
Our API enforces rate limits to ensure fair usage and system stability. If you receive a “Too Many Requests” error:
- Check our rate limit guidelines in the documentation.
- Reduce the frequency of requests or implement caching to minimize redundant calls.
- Consider upgrading your plan if you need higher request limits.
-
Read our guide on How to Avoid API Usage Limits for more details.
3. Incorrect or Unexpected Data
If the API response contains unexpected exchange rates or missing data:
- Verify that the correct currency pair is specified in your request.
- Ensure your API request includes the correct date format if retrieving historical data.
- Cross-check the response with another source to confirm accuracy.
4. API Downtime or Connectivity Issues
If your application is unable to reach our API or receives timeouts:
- Check our status page or Twitter updates for any ongoing outages or maintenance.
- Ensure your server or network is not blocking API requests.
- Try a test request using Postman or cURL to verify connectivity.
5. Slow Response Times
If API responses are taking longer than expected:
- Optimize your queries by requesting only the necessary data.
- Use a local caching strategy to reduce repeated calls.
- Monitor network latency and try accessing the API from a different network or region.
Debugging API Requests
To effectively debug your API requests:
- Use Postman or cURL to manually send requests and inspect responses.
- Pay close attention to error messages and HTTP status codes.
- Validate request headers, query parameters, and payload formats.
Best Practices to Avoid Issues
- Secure Your API Key: Store it in environment variables rather than hardcoding it.
- Stay Updated: Subscribe to API status updates and changelogs.
- Implement Retry Logic: Handle temporary failures by retrying requests with exponential backoff.
- Monitor Usage: Regularly review logs to identify potential issues early.
