curl with use of Local Manager Secrets for Credentials

See more CURL Examples

This example demonstrates how to retrieve secrets from the local credential manager instead of embedding them directly in your source code.

On Windows, this refers to the Windows Credential Manager, and on macOS, it refers to the Apple Keychain.
