I have slackbox running locally, have created a Spotify dev application and have successfully authenticated slackbox. It says I am logged in at http://localhost:5000/. All of my variables have been set, including the slack token, in an .env file via dotenv.
All seems well there.
On the slack side, I have created a slash command mapped to /spotify that POSTs to http://localhost:5000/store. The slash command shows up in my command description list when typing.
When I attempt to use it though, I get an access denied message in chat, I'm assuming due to cross-domain issues:
ERROR: The requested URL could not be retrieved
Access Denied.
According to their docs - https://github.com/benchmarkstudios/slackbox - running this locally should work. I also run a Hubot bot locally and it integrates fine with the same slack room.
Any help is appreciated!
