Using a token to bypass having to sign in to access a hosted feature layer

[AndrewMurdoch1]

Good Day

I'm trying to bypass the sign-in process to access our host feature layer from the ArcGIS JavaScript API, I tried implementing OAuth, following the guides, and used this:

const info = new OAuthInfo({
    appId: "<blah>",
    popup: false
});

identityManager.registerOAuthInfos([info]);

But every time the feature layer load it kicks me over to a sign-in page, and once I sign-in it kicks me back to our application, but to the wrong page and I enter a non-stop loop,. It is possible to use an ApplicationSession and use the Client ID / Client Secret to generate a token, which I can then register to bypass this issue?

We have this function for queries:

authenticate() {
  this._session = new ApplicationSession({
    clientId: '<blah>',
    clientSecret: '<blah>'
  })
}

But I don't see any option to attach the authentication parameters to the FeatureLayer URL

I looked up this page: https://enterprise.arcgis.com/en/server/latest/administer/windows/about-arcgis-tokens.htm  which doesn't explain how to attach or generate the token, unless I'm meant to use the token from the ArcGIS Developer Portal.

Thanks

Solved, if you're trying to do the same thing, try this, making sure to fill in username and password:

const tokenURL = 
'https://www.arcgis.com/sharing/generateToken?username=<>&password=<>&client=requestip&f=json'
this.http.httpGet(tokenURL).then((res: any) => {
  identityManager.registerToken({
    server: 'https://www.arcgis.com/sharing/rest',
    token: res.token
  });

  /* Map Init Here */
}).catch((error) => {
  console.log(error);
})

I have integrated Portal with ArcGIS Server , so authentication procedure is taken care by the Portal. We use SAML OKTA users inside the portal, Is there a any API Endpoints to generate token for this usecase?
