Hello @ranjeet.prasad

The grant_type parameter supports the following values only:

  • password
  • refresh_token (for Refresh access token request)

You can set the username and password in the request body directly as follows.

For the authorization, you can set the { {CLIENT_ID}} as a username, then leave the password blank.

Hello

The access denied error means your account does not have permission to get the RDP APIs authentication token from the RDP Auth service.

Do you have the RDP account? Please note that the RDP APIs account and Eikon account permission are different.

I highly recommend you contact your Refinitiv representative/Account manager to verify your RDP account permission.

Additionally, you can find the Postman step-by-step guide on this Authorization and Time Series Summary (bar) in Postman page.
