Vanity URLs are only associated with the default variant of a parameterized report. The variants with different parameter values are available as paths beneath that vanity URL.
For example, if my default variant has the vanity URL /stocks/, my variant with a ticker="AAPL" setting might have the URL /stocks/vuGRxy2Sp/. The variant with ticker="MSFT" might have the URL /stocks/vhTapsdut/.
The final path segment is the variant "key".
You can find this "vanity plus key" path by visiting any of your variants and then using the "Open Solo" link in the RStudio Connect dashboard.
Could you give us some examples of parameterized reports, their variants, and the URLs you would like assigned to each?
We have been talking about ways to use vanity URLs in more places. I will make sure that parameterized report variants are part of that discussion.
