  client_id: '<your_app_client_id>'
});

document.getElementById('login-button').onclick = (e) => {

    e.preventDefault();
  }

  sdk.popup().authorize().then((authorizeData)=>{
    const transaction = sdk.verify(authorizeData);
    if (transaction != null) {
      // authorization success
      // authorizeData contains `accessToken` or `code`
      // transation contains state and optional code_verifier (code + PKCE)
    }
  }).catch((e)=>{
    
  })
};

Flows

Authorize using a popup. It's possible to pass options to override constructor options.

const sdk = new AccountsSDK(options)
const promise = sdk.popup(options).authorize()

Authorize using iframe. It's possible to pass options to override constructor options. Works when a browser doesn't check for ITP, and user authentication is set.

const sdk = new AccountsSDK(options)
const promise = sdk.iframe(options).authorize()

Authorize using a full redirect. Authorize function performs full browser redirect to an authorization server. authorizeData function checks if authorization is set in URL.

const sdk = new AccountsSDK(options)

sdk.redirect().authorizeData().then((authorizeData)=>{
sdk.redirect().authorizeData().then((authorizeData)=>{
  // authorize data found in URL
  const transaction = sdk.verify(authorizeData);

}).catch((e)=>{
  // authorize data missing, redirect to authorization server
  sdk.redirect().authorize()
})
