Delegated Auth

The establishAuthentication method facilitates the authentication of users managed by your identity provider.

This method requires two parameters. The first parameter must be a string that uniquely identifies the user, and the second parameter is a closure that receives a string as input and outputs a string.

Inside the provided closure, you must send the input string to the designated backend endpoint within your domain to initiate authentication. Upon success, the request should return a string that must be returned from the closure.

If the Vipaso SDK successfully establishes authentication for the provided user, it triggers a callback through the VipasoPayDelegate.onAuthenticationStateChange method with the updated authentication state.

try await vipasoPay.delegatedAuth.establishAuthentication(
    userIdentifier: userIDString,
    connect: { input in
        // Input is a String provided by the Vipaso SDK
        // Send the input string to the dedicated backend endpoint in your domain

        // Return the output string received from your backend
        return output
    }
)

Expect the outcome in the callback at:

extension VipasoAuthenticationConsumer: VipasoPOSDelegate {
  
  ...
	
  func onAuthenticationStateChange(vipaso: VipasoPOSProtocol, authenticated: Bool) {
    if authenticated {
        // Handle successful authentication
    } else {
        // Handle authloss/unauthenticated cases for Vipaso SDK
    }
  }
	
  ...
  
}
