Hello @kishore.karanam

I highly recommend you check the following WebSocket API and RTO tutorials and resources pages first:

• Connect to Refinitiv Real-Time - Optimized Tutorial
• Sending a Request message to the server Tutorial
• Make a Batch Request for Multiple Items Tutorial
• RTO example applications (C#, Java, and Python) from the GitHub repository I highly recommend you check the *service_discovery* example.
• Refinitiv Real-Time - Optimized Install and Config Guide

The above resources will give you a step-by-step guide and a clear explanation regarding how to use the WebSocket connection to connect and consume real-time data from RTO.

You can follow the step in the "Getting Started for Machine ID" of Getting Started with Refinitiv Data Platform article to set up your App Key/Client ID.

1. For Authentication Service, Please confirm if the password to be passed will the password of My Refinitiv and username will be Machine ID

Answer: Yes, the username for the RTO is the Machine-ID (GE-XXXX)

2. How to generate Client_Id and is this mandatory to be passed for authentication?

Answer: The Client_ID (aka App Key) is a mandatory credential for the Authentication process. You can follow the step in the "Getting Started for Machine ID" of Getting Started with Refinitiv Data Platform article to set up your App Key/Client ID.

3. For Authentication service, Please confirm if the following will be the endpoint : https://api.refinitiv.com:443/auth/oauth2/v1/token

Answer: Yes. Please find more detail on Refinitiv Real-Time - Optimized Install and Config Guide

4. For the rest of the service Kindly let us know which endpoint to use (region: Middle East, Dubai) as we will be configuring the same at our end instead of calling service discovery every time.

Answer: The current supported AWS regions are APAC, EMEA, and AMER only. I highly recommend you check the *service_discovery* example the GitHub repository for more detail.

5. For Login Service What will be the ApplicationId and position values?

Answer: The app ID is something that you define and is for your own purposes only. The position is the machine's IP Address in <IP Address>/Hostname format.

Make a Batch Request for Multiple Items Tutorial

Hello @kishore.karanam

I just noticed that you do not want to use the service discovery feature, so I suggest you check the *gw authentication* examples of the WebSocket API - RTO examples.

Regarding the RTO endpoints, you can find the list of current endpoints from the section "Current Endpoints" of Refinitiv Real-Time - Optimized Install and Config Guide document. The current endpoints are available on AMER, EMEA, and APAC regions only.
