I have been struggling to achieve Non-interactive login to Betfair using certificate. I'm using C# and on Windows 10. I'm just testing with sample project: https://github.com/betfair/API-NG-sample-code
- I have app key
- I created certificates with no password following the url: https://www.youtube.com/watch?v=8N-EnnmN59Y&t=51s
Next according to the note from the sample, I created *.pfx for P12. https://github.com/betfair/API-NG-sample-code/blob/master/loginCode/Non-interactive-cSharp/README.md
So I think everything is done in right order but it keeps saying internal error.

Could anyone help me?


everyone. Sorry, there was misunderstanding. The login process asks password during running and I thought it's for the password of certificate. But now I see that it's the password for an account of Betfair. If anyone spent time because of my stupid question, sorry.
I decided to post this as an answer hoping others not misunderstand the flow.
Thanks.
