You're gonna need to upload a sample workbook that shows what you're trying to do.
You can build a string of the dimension values on a sheet and incorporate that into a URL string, and I could show you how to do that if I had an example to work with.
If you need to anonymize your data, follow the steps in the demo video linked here:
Not a terribly difficult thing to do, but you have to be careful about the level of detail you are sending and carefully construct your receiving workbook parameters and filters. As Joe has mentioned, having sample workbooks so we can see your strings that you are sending would be helpful.
Ended up figuring this out. Unfortunately I didn't explain my original problem well enough. Thank you for the help!
