Usage of client.loginClientCredentialsGrant() function

[Kannan_Appukuttan_Sh]

Hi Team,
I am trying to get the real time notification on an angular UI project. I am following the steps mentioned in the post : https://developer.genesys.cloud/notificationsalerts/notifications/subscribe-to-queue

I am getting a console error while accessing the loginClientCredentialsGrant() says "Buffer is not defined" and the code stops there.

Am I missing something on here ?

Can I use the npm package "purecloud-platform-client-v2" to angular project and login the client with CLIENT ID and Secret, create channel and subscribe to the queue (v2.users.${queueId}.conversations) and listen for notification ?

Hello,

The loginClientCredentialsGrant (that uses an OAuth Client ID and Client Secret to get a bearer token) is not meant to be available for Web based apps.
loginClientCredentialsGrant() will only work in a nodejs app.

As you are planning to expose a UI to a user, you need to leverage a different OAuth Grant flow - with user context - as an example, the loginImplicitGrant (about Implicit Grant).

You can find a sample Angular project in our available blueprints. I don't know if all dependencies are up to date, but it shows the use of the Platform API SDK and loginImplicitGrant.

Thanks @Jerome.Saint-Marc for your reply to my query.

I have a UI project and a back end api. So i am able to use the SetAccessToken method in UI. Mine is an angular 11 project.
The SDK "purecloud-platform-client-v2" is working fine in angular 17 project with out any issues, But when I refer the PlatformClient in any version lower than angular 17, I am getting a message below.

Could you please guide me if you know any work around for this issue ?

I don't have much knowledge on Angular so I can't guide you on this.
But I'd recommend to check the project (blueprint) I mentioned in my previous post. This is the Github repo of the project.
It was using Angular 12 apparently - so maybe close enough to your Angular 11.
You can have a look at the angular.json to see how the Platform API SDK is referenced.

There was also this other post on Angular 12 project that may be of interest: How to Add PureCloud SDK to Angular (12)
