Connect to RDP API without InsecureSkipVerify


I am trying to follow this example to connect to the RDP API through some simple Go client:

Now, when I remove the "InsecureSkipVerify" parameter, the requests to Refinitiv fail with "Internal Service Error" id e0ca91aa-68d5-493e-8ec0-c1b2ac617df5.

What is the right way to set up TLS between our client and Refinitiv? I cannot find the relevant information in the Refinitiv Real Time Optimized guide.

Thanks for reaching out to us.

It works fine on my machine. I removed that line from the code and modified the code to use

func getAuthToken(authUrl string, clientId string, clientSecret string, scope string) (string, float64) {
    log.Println(getCurrentTime(), "Sending authentication request...")
    // Send login info for authentication token
    transCfg := &http.Transport{
            TLSClientConfig: &tls.Config{},
    client := &http.Client{Transport: transCfg,
            CheckRedirect: func(req *http.Request, via []*http.Request) error {
                    return http.ErrUseLastResponse

I can get a token and retrieve the real-time data.

Thank you for trying this and confirming on your end, I will need to double check more closely.

Hello @jaleel

I have tried the go example with go version 1.17.12 and the "TLSClientConfig: &tls.Config{}" code (from @Jirapongse) on Linux. The code works fine on my end.

Please note that the RTO *RdpGw_ClientCred_auth* examples (including go's market_price_rdpgw_client_cred_auth.go) support the forthcoming oAuthClientCredentials service only. For the current authentication service, I highly recommend you check the *rdpgw_service_discovery* examples which are available in Java, C#, and Python in the folder.

Ack - thank you for trying it yourself and confirming. I will investigate and follow up here if relevant.
