channels.info deprecated on Slack API

[brownjohnf]

Slack has deprecated the channels.info endpoint (https://api.slack.com/methods/channels.info), and it no longer works at all with apps created after 10 June 2020. You're now supposed to use the conversations.info endpoint (https://api.slack.com/methods/conversations.info), but that doesn't appear to be supported by the crate.

I might take a stab at adding it; I assume it wouldn't be too complicated.

Hey yes shouldn't be too bad 🤞 hopefully no traps, I haven't checked it out

you'll need to add it to the schema repo and use the codegen from this repo updating the sub repo. It gets a little messy but don't worry if it looks funky

I also need this endpoint and had a look at the schema repo. However, I have no idea what I have to do to add it. Do I have to create the json files myself? Can the api_scraper be used to help me create them? Does slack provide the files?

I have been trying to look at the generator too, but without getting anything to work.

I had a look at it and, well the scraper seems to be beyond repair. I created conversation.history manually, because that is the one I needed.

We probably have to rewrite the scraper to use something like this https://github.com/slackapi/slack-api-specs. Question is, @dten are you still around? Cause I don't want to give it a try and than noone is there to merge it.

Also, currently the slack crate only supportes get requests. So, we probably have to touch a lot...

[dten]

Hey I'm still here.

If you want to do an PR to the schema repo that would be great.

The scraper that worked off the docs was a good start but their docs also have the wrong types which means manual corrections.

Last I checked slack's official spec also misses things. Now to be fair ours does too but at least there's something that can be done about that one.
