Errore in Creation of a Datastream Object

Hi.

I've a Datastream Licence and I'm trying to get data from refinitiv.

First, I tried to create a Datasteram Object in the following way:

c = datastreamws('username', 'password');

The script gave me an error:

Error using datastreamws. HTTP is an insecure protocol, use HTTPS instead..

So I tried a solution in an answer here in the community and a I wrote the following code:

d = datastreamws("","","https://product.datastream.com/DSWSClient/V1/DSService.svc/rest/Token? username=user&password=pword")

d.URL = "https://product.datastream.com/DSWSClient/V1/DSService.svc/rest/GetData"

I works, but the script gave me another error:

Error using datastreamws

Login Failed, invalid username or password.

Maybe I wrote user id and pw in a wrong way? if my user is ABC and my password is DEF, it's enough to write like that:

d = datastreamws("","","https://product.datastream.com/DSWSClient/V1/DSService.svc/rest/Token? username=ABC&password=DEF")

d.URL = "https://product.datastream.com/DSWSClient/V1/DSService.svc/rest/GetData"

Or it requires some quotes or double quotes?

Thank you, regards.

I understand you are getting an error while creating a "datastreamws" connection object.

You can refer to the following sample code to create a "datastreamws" connection object-

username = 'ABCDEF';
password = 'abcdef12345';
c = datastreamws(username,password)

You can refer to the following MATLAB documenation links for more information regarding Datastream Web Services from Refinitiv connection-
