I'm trying to call a REST API which requires the use of a Client Certificate to authenticate using the http action.
I'm base64 encoding the pfx file and are supplying the corresponding password but the flow fails with the error message: "Could not load the certificate private key. Please check the authentication certificate password is correct and try again."
I'm using the same certificate to access the api server programatically with no issues. The error message indicates to me that the action is not able to load and use the certificate/password correctly.
Have anyone gotting this authentication mechanism to work properly? If so, how did you generate the certificate you are using?
In advance, thanks!
Hi @ bangorkeith,
Could you please share a screenshot of the configuration of your flow?
Could you please share more details abou the issue that you meet?
The error message told that the flow could not load the certificate private key.
Please take a try to use base-64 encoding the certificate string refer to link below:
Please check the authentication certificate password is correct and try again,please let me know if your problem could be solved.
I faced same issue and solved.
It seemed like base64 decoding did not work well.
so i stored my pfx file at one drive.
and made flow step to read it.
and set it to pfx parameter.
Have you had an opportunity to apply @ozawako1‘s recommendation to adapt your Flow? If yes, and you find that solution to be satisfactory, please go ahead and click “Accept as Solution” so that this thread will be marked for other users to easily identify!
