Slack integration

Good afternoon, everyone,

Just a quick question, I'm interested in the integration between Loomio and Slack. Is this integration possible when you host the solution yourself?

I tried to link the two solutions but it doesn't seem to work. I come across a screen that tells me that the client_id parameter is wrong. Looking at the URL I see that the parameter is empty.

So I created an application on Slack, got a "client_id" and entered it in the URL. This leads me to the authorization requests, and then brings me back to a screen telling me that the solution can't connect to Slack.

Looking at the logs, I get a message :

Do you have any ideas?

Thank you in advance !
