Ask HN: Visual website automation options Axiom, Selenium, or other?

Hello, I'm wondering the best way to do website automation where I have to be logged in. I do not want to give my credentials to a service if I don't have to. The companies website API only lets me do so much and there is a little manual step I have to do with browser. I'm looking to tie this all together. What would be the best solutions for this: I see Axiom as an option but i'm unsure about credentials and how I would trigger it to run the chrome plug-in once a webhook has been processed. Or would I use Selenium some how record what I do and have it mimic that but change input data and it can spit out code I can run on a local server? Basically I have to manually assign a user to a project assign permissions and change the project name. I'm going to be doing it manually but the process might become overwhelming if I get too many requests. Thank you for the advice in advance.
