Performing Manual Authorization Requests

import ZenKeySDK

class LoginViewController {

    let authService = AuthorizationService()

    func loginWithZenKey() {
        // In response to some UI, perform an authorization using the AuthorizationService.
        let scopes: [Scope] = [.openid, .email, .name, .phone, .postalCode]
        authService.authorize(
            scopes: scopes,
            fromViewController: self) { result in

            switch result {
            case .code(let authorizedResponse):
                let code = authorizedResponse.code
                let mccmnc = authorizedResponse.mccmnc
                let redirectURI = authorizedResponse.redirectURI
                let nonce = authorizedResponse.nonce
                let correlationId = authorizedResponse.correlationId // string
                let context = authorizedResponse.context // string
                // Pass these identifiers to your secure server to perform a token request
            case .error:
                // Error is returned identity provider
            case .cancelled:
                // The user cancelled request in ZenKey application.
            }
        }
    }
}

```swift import ZenKeySDK

class LoginViewController {

let authService = AuthorizationService()

func loginWithZenKey() {
    // In response to some UI, perform an authorization using the AuthorizationService.
    let scopes: [Scope] = [.openid, .email, .name, .phone, .postalCode]

            let code = authorizedResponse.code
            let mccmnc = authorizedResponse.mccmnc
            let redirectURI = authorizedResponse.redirectURI
            let codeVerifier = authorizedResponse.codeVerifier
            let nonce = authorizedResponse.nonce
            let correlationId = authorizedResponse.correlationId // string
            let context = authorizedResponse.context // string
            // Pass these identifiers to your secure server to perform a token request
        case .error:
            // Error is returned identity provider

        }
    }

For example, if your app presents its login flow in a WKWebView, you might use the ZenKey button asset from [Integration options on the web](doc:web-integration-options) inside your web content, then a `WKNavigationDelegate` to detect taps on that button before calling the `loginWithZenKey()` function in the above sample code.
