Determining the instrument RIC
The first thing is to determine which RIC contains the Canadian Dollar Offered Rate (CDOR) you are interested in. There are actually several, which you can find by using our Eikon product, or the RIC search tool in this portal, and typing CDOR as search criteria.

That said, please note this forum is aimed at software developers using Refinitiv APIs. The moderators on this forum do not have the required deep expertise in all the content sets available through our products to precisely answer your question. I advise you to call the Refinitiv Helpdesk number in your country. They will either have the answer for you right away, or will reach out to the content experts who can provide the answer you're looking for.
Requesting data for a RIC
Once you have the RIC(s) you need, you can request the data. You do not specify what "details" you are interested in, so I'll give you a generic answer: when you want to find a specific data field, you should check the DSS Data Content Guide. Open tab "Field Descriptions", and use a text filter on column D or E to display only the rows that "contain" a keyword that defines what you are looking for. The results will show in column C which templates (request types) will deliver that field. Base on that you can request the data, using either the GUI or the API. Our tutorials show many examples of data requests.
