Hello,
I’m Numan, a web development expert with over 7 years of experience in PHP, custom solution development, and code debugging. I’ve worked on complex integration projects, including troubleshooting issues with communication between systems and external services, such as online billing systems and similar platforms.
I understand that after an IP change on your hosting, you are facing difficulties with online invoicing, particularly with authentication and data transmission issues with AFIP. These types of issues are often related to IP configurations, security certificates, and authentication parameters in API communications with AFIP. My experience in this field allows me to offer an effective solution to debug the code and resolve these errors.
To address this, I would review the error logs, check the AFIP API configuration, and ensure that the authentication credentials are correctly implemented. I would also conduct thorough testing to ensure that data transmission is secure and seamless.
I look forward to your response so I can assist you quickly and effectively.
Best regards,
Numan
