ViewsAzure AD B2C REST API endpoint for user authentication
I am trying to authenticate users for my Reactjs-based application through Azure AD B2C service. While going through the documentation, I found 2 ways - popup and redirect, but both these options have some limitations like if I want the login/signup form very customized or I want a callback to be returned on new user signup etc. Also, I am using AD to authenticate users for React Native mobile application and in that I have to use webview for redirect which doesn't give a very native feel.
A solution for these limitations some forums gave was to use API connectors but again I wasn't able to find some good documentation for that.
Can anyone help in determining a good approach for user authentication and signup with a custom form that I can create, maybe by using some API endpoints or any SDK for that purely on the frontend-side ?

• A good approach would be to create user flows for login/signup and authentication in Azure AD B2C by registering your react js application in app registration. Once the app has been registered, configure the API access label and the signup/login user flows for that app registered. Once that is done, create a file named B2C.js and add the code below for adding the ‘msal’ authentication library in it for providing authentication to the react js app deployed.
‘ var msalAppConfig = {
auth: {
clientId: '<client Id>',
authority:'https://<TenantSubDomain>.b2clogin.com/<Tenant>/<signInPolicy>',
redirectUri: '<Redirect Url>',
validateAuthority: false,
postLogoutRedirectUri: 'window.location.origin'},
cache: {
cacheLocation: 'sessionStorage',
storeAuthStateInCookie: isIE()
} ‘
• Replace the values of ‘client id’, ‘redirect url’ and other ‘<>’ values that can be filled through the application created in the azure ad b2c app registration field. Once done, the login/signup page will look as below: -
• Ensure that the index.js and the b2c.js file is properly edited will required details so that authentication happens correctly through azure ad b2c.
