GetUserInfo: http Post or Get?

[WZRPW]

The Slack-api Golang code uses the HTTP post for GetUserInfo:

slack/users.go

Line 239 in 792f7ed

func (api *Client) GetUserInfo(user string) (*User, error) {

But Slack API doc says it is HTTP Get:
https://api.slack.com/methods/users.info
I am confused. Which one is incorrect? Thanks,

Technically, both HTTP methods work! This is the same for other endpoints too. The preferred HTTP method in the document is a recommendation.
