Slack REST API documentation

Is there any documentation about the REST API for Slack integrations? I’ve found nothing online. I can see the network call to create a new integration in the browser network tools but that is all. Mostly I’d just like to get a list of integrations that already exist for a repo.

I’m not from BB-team, but I think you can navigate to /plugins/servlet/restbrowser#/ and search for slack.
At least if you are talking about this extension.

Yes, this is for the official Slack plugin. I had to install the Rest Browser plugin ( Once I did that then I was able to see the Slack endpoints (also had to uncheck “Show only public APIs”). Thanks for the help.
