I want to be able to verify a token, against the server it had been created on. I have the Twilio account and I can generate the Access Token (specifically, i need it for the Twilio Conversations, but this is beside the point). I want to be able to send that token back, from the client to the server so that server can actually verify that it is valid token, generated on that particular server itself. It doesn’t have to be with correct grants, in course of validity (i.e. not expired), or anything. I just want to check on the server that it is valid token, generated from that server, with that server’s secret and Twilio API. How can I do this?
