When I finalize the login with the Nightbot I get a parameter code with numbers… What can I do with it?
That code is the ‘authorization code’ you will need that to get the acccess tokens.
See step 3 in the docs: https://api-docs.nightbot.tv/#authorization-code-flow
How i do that?
It’s all explained in the docs. Did you check the other example in your other post?
