I am new here, please let me know is there any certification available for open rpa and where from i can learn open rpa from scratch.
Welcome.
We have some very basic documentation at docs.openiap.io/docs/openrpa/
You can find TONS of videos on YouTube about OpenRPA at youtube/openrpa
I have not seen this myself, but I have talked to multiple people who said they really enjoyed this course made by a 3rd party at robotic-process-automation-rpa-with-openrpa
