SLAS Support for Custom Parameters and Hooks

Custom parameters can be passed to the following SLAS endpoints:

/login. When applicable, SLAS passes custom parameters to the OCAPI SHOP /customers/auth hooks.
/authorize. When applicable, SLAS passes this information to 3rd party IDPs.

Make sure you prefix the parameter names with c_.

For the /login endpoint, SLAS forwards custom c_-prefixed headers (with values matching [a-zA-Z0-9-._]) to the B2C Commerce platform.
There are no SCAPI hooks for the /login and /authorize endpoints. /login runs /customers/auth hooks and /authorize runs no hooks.
