Question

I am trying to find docs to figure out what the max limit is for YouTube and twitch channel names, but I am unable to find one.

This post suggests it's 20 but this post is like 3 years old. Plus the official YouTube API page doesn't list anything like that. Does anyone know what the limits are?

Answer 1

As of the YouTube V3 API, when creating a new channel, your channel name comes from your Google Account name:

First and last names support unicode/UTF-8 characters, with a maximum of 60 characters.

Name and password guidelines

The API docs only explicitly disclose the maximum number of characters for a video title (100) and a channel description (1000).

I don't believe this information is available for Twitch through their API.

根据this reddit post和this post on the Twitch Developer Forums：

4至25个字符
字母，数字，下划线

引用reddit答案，有效的用户名似乎是由正则表达式定义的：

EXECUTE format('UPDATE %I.%I SET %I = REPLACE(%I, $2, $3)', 
                matching.schemaname, 
                matching.tablename,
                matching.columnname,
                matching.columnname)
  USING regex, replacement;

注意：

这两个来源都不是官方文档，但是看起来都可信
Twitch上的用户名等于频道名称，但与显示名称不同
