Hey @ashOne,

On the Visa Developer Platform, the different certificates serve various purposes, primarily focused on ensuring secure communication and authentication. Here’s a concise explanation of each:

1. Visa Development Platform Certificate:
- Purpose: This certificate is specific to the Visa Developer Platform and is used primarily for authenticating and securing API requests.
- Usage: When you make API requests to Visa, this certificate helps in establishing a secure connection between your application and Visa's servers. It ensures that the data being exchanged is encrypted and secure.

2. DigiCert Certificate:
- Purpose: DigiCert is a widely recognized Certificate Authority (CA) that provides digital certificates for websites and applications to enable secure SSL/TLS connections.
- Usage: When Visa or a merchant uses a DigiCert certificate, it ensures that their server is trusted and that communication with it is secure. DigiCert certificates are often used to secure websites and can also be used for client certificates in API communication.

3. DigiCert Global Root CA Certificate:
- Purpose: This is the root certificate from DigiCert, which is at the top of the certificate chain of trust.
- Usage: The DigiCert Global Root CA certificate is used to verify that DigiCert-issued certificates are legitimate. When your system trusts the DigiCert Global Root CA, it inherently trusts all certificates issued by DigiCert, including those used by Visa and other entities. It is essential for validating the entire certificate chain, ensuring that all intermediary certificates and the end-entity certificate (like the Visa Development Platform Certificate) are trusted.

Summary

- Visa Development Platform Certificate: Specific to Visa's API interactions, for securing API requests.
- DigiCert Certificate: General-purpose SSL/TLS certificate issued by DigiCert for securing communications.
- DigiCert Global Root CA Certificate: Root certificate to establish trust in the certificate chain issued by DigiCert.

Each certificate plays a role in establishing and maintaining secure and trusted communications between clients and servers.
