Posted on by Lennart Jongen 5

Hi,

I want to read customer data from dynamics crm using the programming language R. I try to use an API to do that. This is my code:

library (httr)

usr <- "yourusernamehere"
pwd <- "yourpasswordhere"
url <- "https://companynamehere.api.crm4.dynamics.com/api/data/v9.1/"

GET(url,authenticate(usr,pwd)

Response [https://companynamehere.api.crm4.dynamics.com/api/data/v9.1/]
  Date: 2019-11-19 09:30
  Status: 401
  Content-Type:

I get status 401. My username and password is 100% correct.  I tried the api also for the microsoft Business central. The same method worked succesfully for Microsoft Business Central. 

Can somebody help me out. Great thanks in advance! A solution in python is also welcome.

    Hi Lennart,

    are you sure the url is companyname.api.crm4.dynamics.com? I only use companyname.crm4.dynamics.com

    Regards,

    Daniel

    That still doesn't work. When I paste the 2 urls in the webbrowser I gain the same result. Is that weird?

    Ok sorry, my misstake. The URL for OnPremise and Online are different. What is the result if you put companynamehere.api.crm4.dynamics.com/.../ directly in the Browser?
