First, you need to check if your credential is allowed to access API. You can go to this Datastream TEST REST Service page to check your credential.
Next, you can refer to the Getting started with R document that provides information on how to access DSWS via R. You can also refer to the Setup Jupyter Notebook for R article which provides an R example running on Jupyter Notebook.
Then, you can go to Datastream Navigator website to search for instruments and data types that can be used to retrieve the required data.
For example, the code looks like this:
data <- mydsws$timeSeriesRequest(instrument = c("S&PCOMP", "FTSE100"),
datatype = c("PI","VO"),
startDate = "2012-01-01T00:00:00",
endDate = "LATESTDATE",
frequency = "D",
)
data
The output is:
Otherwise, you can contact the Refinitiv Datastream Web Service support team directly via MyRefinitiv to verify your credential and find instruments and datatypes used to retrieve the required data.
