I am developing a chat app in Android using Twilio. I went through this link. If I am not mistaken then; to do chatting, a server must send a token to a client. Once client get's that token then he is ready to initialize Twilio SDK and do chat after that.
My server is written in go-lang, so thought of using my existing login system. Just wondered, how can I grant the access to the token generated by my server? I did not see any REST API for granting the access for that token.
Also when I went through the example given by Twilio, they have used capability token. How a capability token is different from access token?
