YouTube

To anyone interested, I figured out how to do an authenticated request to /youtubei/v1/player. First you have the normal body:

{
   "context": {
      "client": {
         "clientName": "WEB",
         "clientVersion": "2.20210708.06.00",
      }
   },
   "videoId": "bO7PgQ-DtZk"
}

probably can adjust the client as needed. You still want to add the key to querystring as normal. Next, you need these headers:

"X-Origin","https://www.youtube.com"
"Authorization","SAPISIDHASH 1625981319_5d6eb..."

Finally, you need these cookies:

Name: "__Secure-3PSID",
Value: "_gdNhnpLL2zVVA9c-gj53X-bZQipAWuXEccm0..."

Name: "__Secure-3PAPISID"
Value: "VFKYV_f44SBoEuOa/AxyyZj1QZKPY..."
