I simply want to write a script (maybe Groovy, Java or Postman) allowing me to update my own questions and answers, maybe in some cases also other people's. My concrete use case is to update links to AspectJ release notes and documentation, because I posted hundreds of answers about AspectJ, often linking to documentation. But the URLs and the document structure for the AspectJ documentation will soon change completely. I want to keep my posts helpful by automatically updating content linking to old URLs by updating them. I am not an admin on the old website and cannot set up server-side redirects. Finding and changing all links manually would take days, so I want to automate it. It is absolutely no problem to authenticate manually in the browser and copy the token into my script every time it runs. I am also 100% fine with the script doing things in my name, because I am not going to do anything abusive.
