Class: `UPerformAuthenticationAsyncAction`

//  PerformAuthenticationAsyncAction.h : 40

class NBPATREONAPICLIENT_API UPerformAuthenticationAsyncAction
    : public UCancellableAsyncAction;

Reflection-enabled

This action can be used to perform authentication with the Patreon API. The user's default web browser will be opened to allow them to sign in, a local HTTP server will be started to receive the authentication response from Patreon, and finally a request will be made to obtain an access token for the authenticated user.

The returned access token can be used to make additional requests to the Patreon API, e.g. to obtain information about the authenticated user and their pledges to determine if specific content should be unlocked for them.

IMPORTANT NOTE:

Because everything is being handled within the same process, using this action requires that the application have a copy of your client_id and client_secret, both of which will be included in HTTP requests sent to Patreon from the user's computer. This means that the user may be able to extract these values either from the packaged binaries or by analyzing their network traffic during the authentication process.

NEVER use your creator token here!

Reflection-enabled

Specifiers:
- BlueprintCallable
- Category = NBPatreonAPIClient|HTTP
Meta Specifiers:
- DisplayName = Make Patreon Auth URI
- Keywords = NBPatreonAPIClient

const FString ClientID
```
  Patreon app Client ID
- CallbackURI
```
const FString CallbackURI
```
  URI to redirect the user to after successfully authenticating
- id
```
FString id = TEXT("")
```
  Optional session/state/id value which will be passed back to the CallbackURI after authentication. This can be used to match a specific request to a specific response if necessary.
Returns
- ```
FString
```
PerformAuthenticationAsyncAction
```
//  PerformAuthenticationAsyncAction.h : 54

public:

PerformAuthenticationUMGAsyncAction

//  PerformAuthenticationAsyncAction.h : 77

public:
static UPerformAuthenticationAsyncAction* PerformAuthenticationUMGAsyncAction(
    const UObject* WorldContext,
    UWebBrowser* BrowserWidget,
    const FString ClientID,
    const FString ClientSecret,

Specifiers:
- BlueprintCallable
- Category = NBPatreonAPIClient
Meta Specifiers:
- DisplayName = Perform Authentication (UMG Browser)
- Keywords = NBPatreonAPIClient
- WorldContext = WorldContext
- BlueprintInternalUseOnly = true
Performs OAuth login to Patreon using a UMG WebBrowser widget. (Requires the WebBrowser plugin to be enabled in your project)

IMPORTANT NOTE:

Due to limitations of the WebBrowser widget, users will need to sign in using their e-mail address. SSO methods like "Sign in with Google" will fail because these rely on opening a second browser window.

Arguments
- WorldContext
```
const UObject* WorldContext
```
- BrowserWidget
```
UWebBrowser* BrowserWidget
```
  Widget to use to display the login page
- ClientID
```
const FString ClientID
```
  Patreon App client_id
- ClientSecret
```
const FString ClientSecret
```
  Patreon App client_secret
- CallbackRoute
```
const FString CallbackRoute = TEXT("/login")
```
  URL fragment (after hostname and port) to expect the login callback to invoke
- CallbackPort
```
const int32 CallbackPort = 8080
```
  Port to listen on for the login callback
Returns
- ```
UPerformAuthenticationAsyncAction*
```
