I have a web site that has [VB.NET](http://VB.NET) as the code behind where I want to verify if a particular channel is live.

According to the Twitch API documentation:

```auto
curl --location --request
GET 'https://api.twitch.tv/helix/search/channels?query=a_seagull' \
--header 'client-id: wbmytr93xzw8zbg0p1izqyzzc5mbiz' \
--header 'Authorization: Bearer 2gbdx6oar67tqtcmt49t3wpcgycthx'

```

header 'client-id: Is this my client ID?  
header 'Authorization: Does Bearer need to be in there?

I used to have this working, but with the expiration of the old APIs it no longer works:  
Dim stringGetInfo As String = New WebClient().DownloadString(“[https://api.twitch.tv/helix/search/channels?query=](https://api.twitch.tv/helix/search/channels?query=)” & stringTwitchID & “&client\_id=”)

Could someone be so kind as to provide a [VB.NET](http://VB.NET) example for this?

I have tried every which way and Googled, my fingers off but I have not been able to find any good examples and those I have tried always result in 401 errors.

I appreciate any assistance.

Yes

Yes

The header is

```
Authorization: Bearer YOURTOKEN

```

They also both have to be Headers

Also probably not a good use of a the search endpoint, you want the “Get Streams” endpoint.
