Hello
I have been trying to integrate the Visa API into my Python application using Two-Way SSL for secure communication. However, I keep encountering issues with SSL handshake and "Two-Way (Mutual) SSL test failed" errors. I suspect there might be an issue with my SSL certificate setup. Can anyone guide me on how to verify if my SSL certificates are configured correctly for the Visa API integration? What are the necessary steps to ensure the certificates, keys, and credentials are valid and properly formatted for a successful connection to the Visa sandbox?
Any tips for troubleshooting SSL-related problems during the integration process would be highly appreciated.
Thank you!
Verifying the SSL certificate setup is crucial for a successful Visa API integration using Two-Way SSL. Here are the necessary steps to ensure your SSL certificates, keys, and credentials are correctly configured for a secure connection to the Visa sandbox:
Obtain the Required Certificate Files:
Verify Certificate Files Validity:
Ensure Proper File Paths:
Use the Requests Library for API Calls:
If you are using the popular requests library to make API calls in Python, configure the SSL certificate files in the requests library. Include the paths to your SSL certificate and private key in the cert parameter:
Verify Certificate Chain:
Debug SSL Handshake Errors:
Enable debug logging in your Python application to get more detailed information about the SSL handshake process. This will help you identify the specific issue during the SSL negotiation.
Test in a Sandbox Environment:
Contact Visa Support:
By carefully verifying your SSL certificate setup and following these steps, you can increase the chances of a successful Visa API integration using Two-Way SSL for secure communication. Happy coding!
