I am trying to use the GET Request node (for access to Osisoft PI data). But I always get the same error "Execute failed: Wrong status: 401 Unauthorized". For Authorization my Windows credentials should be fine but it seems that Knime cannot use these.
Do you have any suggestions for me to solve this issue?
You probably need to specify an Authorization header https://pisquare.osisoft.com/thread/11669
thank you for you quick answer. Could you give me a instruction how to create the authorization Header.
Here is what I already tried:
- Add Header parameter
- Header Key: Authorization
- Header value: here I am not sure what to type in, it should be something like Basic 'API key and Passwort in base64' (?)
- Value Kind: Constant
Am I on the right way to solve the Problem?
Thank you very much.
I just found out that my Server is using for authentication negotiate... is there any possibility to include this in the Request Header of the REST node?
Hello, is there any progress on this topic?
I'm having the same issue. I've tried with all authentication options in KNIME 3.5.1: NTLM, Basic, Digest but I haven't been successful.
Hello, same problem here I can get the data through postman perfectly and when replicating to Knime it only returns the error of this forum
Looks like your question in being addressed in this separate thread:
hello, I’m trying to get data from an API that uses header data as an authentication key, but when I enter the information in the GET REQUEST it returns the error below:
obs: I tested it on the postman and it returns the data
I’ve looked on other knime forums but haven’t found anything that can help me
Please don’t revive old threads if you are already discussing the issue elsewhere. Thanks!
