Error 404 from Create Entitlement Grants Upload URL

[Dongchan_Shin]

I got a Error 404 at Create Entitlement Grants Upload URL API.
I want to notify the drops viewers about earned Rewards.
Please help me.

1. get app access token API.
   -REQUEST
   POST https://id.twitch.tv/oauth2/token?client_id={clientId}&client_secret={clientSecret}&grant_type=client_credentials
   -RESPONSE
   {
   “access_token”: “TOKEN-REMOVED”,
   “expires_in”: 5019679,
   “token_type”: “bearer”
   }

2. create upload URL API
   -REQUEST
   *header
   Content-Type: application/x-www-form-urlencoded
   Authorization: Bearer TOKEN-REMOVED
   Client-ID: {clientId}
   POST https://api.twitch.tv/helix/entitlements/upload?manifest_id=123456789&type=bulk_drops_grant
   -RESPONSE
   {
   “error”: “Not Found”,
   “status”: 404,
   “message”: “{\n “status”: 404,\n “message”: “Service not found”,\n “error”: “Not Found”\n}”
   }

This issue resolved.
Reason is I do not set vhs data end point at twitch drops setting.

Glad it was resolved! I edited out the OAuth token on your behalf so no one can use it to make API calls. Please be careful to not include tokens when sharing code
