Request to Enable "Market Data Feed V3 – Read" Scope for App: Main

Developer API
1

Hi Upstox Team,

I would like to request enabling the “Market Data Feed V3 – Read” scope for my application.

App Details:

  • App Name: Main

Current Issue:
I am able to successfully use REST APIs (holdings, positions, orders) with my access token, but when attempting to
connect to the Market Data Feed V3 WebSocket, I receive the following error:

Error Code: UDAPI100050
Message: Invalid token used to access API

The WebSocket authorization endpoint (/v3/feed/market-data-feed/authorize) is returning this error even though my
token works for all other API calls.

Please enable the “Market Data Feed V3 – Read” scope for my application.

Thank you!

Hi @Manish_52465805

Market Data Feed v3 is enabled for all users.

The error message indicates that the access token is invalid. Please verify that you are using a valid and unexpired access token.

You can refer to the following documentation for generating an access token:

Thanks!
