Troubleshooting

Check API Status

Before proceeding with more complex troubleshooting, check the UCanPay Status Page to ensure there are no ongoing issues with the API service.

Verify Your API Keys

Incorrect or expired API keys are a common source of errors.

Resolution:

• Double-check that your API keys are correct and active.

• Ensure they are being included correctly in your API requests.

Review API Documentation

Ensure that your request conforms to the specifications outlined in the UCanPay API Documentation. This includes endpoint URLs, required parameters, and the HTTP method used.

Use the Correct HTTP Headers

Properly set HTTP headers are crucial for API requests to be processed correctly.

Resolution:

• Confirm that you're setting the correct Content-Type and other necessary headers.

• Include any required authentication tokens or API keys as specified.

Connection Errors

Problem: Failure to establish a connection with the UCanPay API.

Resolution:

• Verify network settings and ensure your server can reach the UCanPay endpoints.

• Check firewall and DNS settings to allow outgoing connections to UCanPay.

Timeout Errors

Problem: API requests to UCanPay are timing out.

Resolution:

• Increase the timeout settings in your client.

• Consider reducing the size or complexity of your requests.

SSL/TLS Handshake Failures

Problem: SSL/TLS handshake errors when connecting to the API.

Resolution:

• Ensure your system time is correct.

• Update your SSL/TLS libraries and certificates.

Frequent 500 Internal Server Errors

Problem: Receiving frequent 500 status codes from the API.

Resolution:

• Implement retry logic with exponential backoff.

• If the issue persists, contact UCanPay support for more detailed investigation.

Data Format Issues

Problem: Receiving errors related to the format of the data sent.

Resolution:

• Validate the JSON or XML data against the schema provided in the API documentation.

• Use tools like Postman or curl to test and debug your API calls.

Logging and Monitoring

Implement comprehensive logging and monitoring for all API interactions. This will create an audit trail that can be invaluable for troubleshooting and understanding the history of API usage.

Error Reporting

Consider implementing automated error reporting tools that can capture and alert you to failures in real time.
