Hello @Karthik,
Welcome to the Klaviyo Community!
You can typically download a site’s SSL certifications by:
- Click the Secure button (a padlock) in an address bar.
- Click the Certificate(Valid).
- Go to the Details tab.
- Click the Copy to File… button.
- Click the Next button.
- Select the “Base-64 encoded X. ...
- Specify the name of the file you want to save the SSL certificate to.
- Click the Next and the Finish buttons.
You can also find similar instructions with images in the Export & Download — SSL Certificate from Server (Site URL) Medium article.
Out of curiosity, what would be your use case in knowing a site’s SSL certification? If you were trying to connect and integrate Klaviyo via API, we have a variety of methods and endpoints you can use as highlighted in our Developer’s Portal.
