Configure HTTP Basic Authentication for REST

See more REST Examples

Demonstrates Rest.SetAuthBasic, which configures HTTP Basic authentication from a username and password. Chilkat automatically adds the Authorization header to each request sent through the object.

Background. HTTP Basic authentication transmits credentials with every request, so it should be used over HTTPS. Credentials should be obtained from a secure source rather than hard-coded in production code.
