Hi @isanchez

I discussed this with your account team and later in the day I tried to recreate your scenario.

I am now able to connect using your MachineID to a t1 endpoint e.g.

amer-3-t1.streaming-pricing-api.refinitiv.com

I can also connect using the service discovery examples mentioned previously - which automatically select a valid endpoint for you.

IF I try to connect to the wrong tier e.g. t2, I get the following:

Login Rejected. Watchlist size of 2500 for 'WS JSON2' connection

Which is now showing a non-zero watchlist size.

Note that because you're on a trial you will only be able to access certain delayed RICs e.g.

/EUR=

where / = delayed and EUR= is the RIC e.g. for EURO

Your account team should be able to confirm which set of RICS you are licenced for.

If you try to request an unlicensed RIC you will see something like:

Text":"Access Denied: User req to PE(xxx)

Hello @isanchez,

You are connecting to a specific RTTO endpoint via wss://amer-3-t2.streaming-pricing-api.refinitiv.com/WebSocket/ address.

Most likely you are not connecting to the appropriate endpoint, based on what tier you are assigned as RTTO customer.

The tiers are 1, 2 and 3, if you do not have this information, you can find your assigned tier from your Refinitiv account manager.

Currently you are connecting to tier2 via t2.

I would like to suggest, instead of connecting to a specific endpoint, to try example market_price_service_ discovery, that can be downloaded as Websocket API Sample Applications. This example should discover the appropriate endpoint to connect to on your behalf.

Hello @isanchez,

I would recommend using discovery mechanism in market_price_service_discover.py instead of pointing directly to the specific endpoint, as it also means that if the specific endpoint is temporarily unavailable, your connection is assigned to an available endpoint and succeeds.

More information on the currently available endpoints can be found in Refinitiv Real-Time - Optimized Install and Config Guide, section Current Endpoints.

From my checking. amer-3-t2.streaming-pricing-api.refinitiv.com supports TCP connection which is for Refinitiv Real-Time SDK.

To use the WebSocket connection, you need to connect to the following endpoints.

Hi @isanchez

Were you able to connect using the Service Discovery examples mentioned above?

The tier 2 (t2) endpoint you tried to connect in your original post supports a watchlist size of 3k-20k - which (according to the error) your machine ID is not permissioned for.

So, you should try a tier1 or tier3 endpoint e.g.

amer-3-t1.streaming-pricing-api.refinitiv.com (watchlist size of 1-3k)

amer-3-t3.streaming-pricing-api.refinitiv.com (watchlist size of 20k-50k)

However, as mentioned by my colleagues it would be better to use the service discovery mechanism - which will discover the appropriate endpoint and also provide alternative endpoints in case one is unavailable.

Hi @umer.nalla, with the first one I got

RECEIVED:[{"ID":1,"Type":"Status","Domain":"Login","Key":{"Name":"AQIC.."},"State":{"Stream":"Closed","Data":"Suspect","Code":"UsageError","Text":"Login Rejected. Watchlist size of 0 for 'WS JSON2' connection is outside of range [20001,50000] supported for this ADS fanout tier for this type of connection."}}]

And with the second one

RECEIVED:[{"ID":1,"Type":"Status","Domain":"Login","Key":{"Name":"AQIC5wM2LY4SfczYS0WaP5d3p3zCUhB0UgwCyPR5kY%2BrnIY%3D%40AAJTSQACMjAAAlNLABMtNTA5ODgzMjQ2MDE5NDU4NzI5AAJTMQACMzQ%3D%23"},"State":{"Stream":"Closed","Data":"Suspect","Code":"UsageError","Text":"Login Rejected. Watchlist size of 0 for 'WS JSON2' connection is outside of range [20001,50000] supported for this ADS fanout tier for this type of connection."}}]

In both case the auth method to retrieve the token was OK

{ "access_token":"eyJ0eXAiOiJhd.", "expires_in":"300" , "scope":"", "token_type":"Bearer" }

I execute the market_price_service discovery found in this link

https://github.com/Refinitiv/websocket-api/tree/master/Applications/Examples/RDP/python

And i Got

Sending authentication request with password to https://api.refinitiv.com:443/auth/oauth2/v1/token

Refinitiv Data Platform authentication HTTP code: 401 Unauthorized

Thanks

Hi @isanchez

The messages you show above indicate that on both occasions you tried to connect to a t3 endpoint which you are not licenced for.

If you had connected to a t1 endpoint and were not licenced, I would have expected to see the following:

Login Rejected. Watchlist size of 50000 for 'WS JSON2' connection is outside of range [1,3000] supported for this ADS fanout tier for this type of connection.

Please try again ensuring you are trying to connect to amer-3-t1.streaming-pricing-api.refinitiv.com

Also, please ask your Account Manager to contact me directly - I will also try to identify and reach out to them.

Hi @isanchez

Thanks for confirming - I was puzzled by your previous reply which said that for both t1 and t3 endpoints you received "Login Rejected. Watchlist size of 0 for 'WS JSON2' connection is outside of range [20001,50000] supported for this ADS fanout tier for this type of connection."}}]

which did not make sense.

Your account manager has made contact and I have asked him for your MachineID so I can check what you may be licenced for.

I am not a licensing person, I am API specialist- but my suspicion at this point that your MachinedID licence has been incorrectly configured.

I will discuss this with your Account Manager and report back.
