I am currently working with a set of APIs which require SSL certificates to be referenced in GET requests.
The API documentation provides examples of such requests as they would be executed using cURL.
However, I cannot see a way to execute the same command in KNIME’s GET Request node. Is it possible? I have all the certificates required (three .pem files) but don’t know how to point KNIME to them for this purpose.
FYI, the format of the cURL command is as follows: -
I was not able to do this with native KNIME nodes but, for anyone else who has this issue in future, I was able to do it using KNIME’s ‘R’ integration.
The ‘R’ Package RCurl has syntax that accepts SSL certificates as parameters with getURL requests.
Inside the R to Table node, you can write a script similar to the following: -
You’re welcome! There may be native KNIME solutions as well since others have posted solutions about using SSL with MySQL connectors. But I couldn’t find anything specifically relevant to API requests.
