Hi @aaandrew,
Welcome to the Auth0 Community!
To get a JWT access token for a user who has authenticated and triggered the Post-Login Action, please follow our Call Your API Using the Authorization Code Flow documentation.
I see that you are on the right track, as you are already calling the /authorize
endpoint to get a code to exchange it for an access token to the /oauth/token
endpoint.
Everything looks correct. However, since you have not been getting the custom claims, I would recommend reviewing your Action script and using console.log()
statements to debug and see what is preventing the claims from being appended.
I would also urge you to check out our Adding custom claims to tokens FAQ.
Please let me know how this goes for you.
Thanks,
Rueben
