I have ASP.Net core API and I am consuming VISA merchant locator send box using (myProject_keyAndCertBundle.p12) certificate path is my local machine. Please suggest how we can use azure key vault to store certificate and then how asp.net core will load and use that certificate to call VISA API?
I will look into this and get back to you when I have more information.
Since your question is pertaining Microsoft products/services, I suggest reaching out to them should you wish to call the APIs using azure key vault and ASP.NET.
Please refer to the Quick Start Guide for Visa Developers. On the left side menu of the page, you can click on Certificate Expiration for further details about certificates.
