I have a NextJS app, Supertoken is running on the frontend, Supertoken is running on the NextJS API route, the core is running in Docker. Now I have a separate API running Fastify, I would like to use the 
Authorization: Bearer
method to verify session on the separate Fastify API, how can I extract the access token from the frontend to include in the headers? Is there a hook available for it? I can't seem to find it. Also, is my idea even possible? Can I verifySession on another API that doesn't not run Supertokens backend?

Hi @Justine What frontend SDK and version are you using?
j
frontend SDK for NextJS, I'm using 
supertokens-auth-react
version 
^0.32.3
@nkshah2 thanks for the quick response! Really appreciate it 🙂

Happy to help. The Session recipe exposes a 
getAccessToken
function on the frontend that gives you the access token. You can attach that as a bearer token to requests.
The access token is a JWT so you can use any JWT verification library to verify it
Or if you want to use the verifySession middleware function you could also have your fastify server call some API on the server that uses SuperTokens. That API would call getSession internally and then give you the result back

interesting! I tried the 
getAccessToken
function but it returns me 
undefined
. Let's me try again, maybe I'll record a short video. Would you be free for a quick Discord channel call?

What version of supertokens-node are you using?
j
^14.0.2

You can set 
exposeAccessTokenToFrontendInCookieBasedAuth
to true when initialising the Session recipe. This will let the frontend read the access token
j
interesting! Ok let me try, will report back in 5 mins
that works! Thanks so much!
