@razibkani Hi again.
Users can have both Session tokens and Access tokens.
Session tokens and Access tokens are generated via Platform API call. I’m not sure how your application currently generates user tokens. If you are already using Access tokens for chat then you can use the same token for Calls. If you are generating Session tokens for chat you will need to also generate an Access token for each existing user.
Note: you should have a server between your client side application that requests to Sendbird to generate the user tokens.
I’ve attached a short document explaining the difference between Session Tokens and Access Tokens.
