this should include this as well:

aside from the missing fields i mentioned, this appears to be working.

is it possible to change the SetSlackApplication to return the SlackApplicationProperties struct w/ the response instead of needing to get another get call?

[svanharmelen]

Nice catch, added them to the struct 👍🏻 And no, the API doesn't return the properties on the PUT call, so it needs another GET call is you want the updated/saved properties from the server...

[jgangemi]

it does - all the json output from our discussion in #2040 was from the PUT request.

[jgangemi]

settings := new(SlackApplication)
req, err := s.client.NewRequest(http.MethodPut, u, opt, options)
if err != nil {
	return nil, err
}

resp, err := s.client.Do(req, &settings)
fmt.Println("-- SetSlackApplication --")
fmt.Printf("Inheritted: %t\n", settings.Inherited)
fmt.Println("-- SetSlackApplication --")

go run slack-test.go
