Iā€™m using the Demo version of KEPServerEX 6.14 and I would like to import a CSV into the datalogger using the API.
I followed the instructions in this github https://github.com/PTCInc/Kepware-Example-Scripts/tree/master/Datalogger/CSV%20to%20DataLogger%20API but I got a HTTP 401 error:

Any ideas?
Thanks

Hi,
After multiple attempts, I decided to uninstall Kepserver completely and reinstall it.
I had been using version 6.5 previously and then installed version 6.14 without deleting all data, which I believe caused the issue. It is now functioning properly.

 

Thanks for your assistance!

A 401 error is an authentication error. Can you confirm that you are passing the correct user credentials to the API endpoint?

In the setup json file, I'm writing the user and password defined during the Kepserver installation. Is this correct?

Best regards.

While I have never tried it this way (and at this time cannot confirm either way), according to this article on REST, it should work if the credentials are being passed correctly:

I can check with our engineering team to see if this has been tested or not.
