I would like to download pdfs of different queries from the following site
However as the link does not change with each new query of municipality, I do not know how to download in scale to several municipalities, because the package curl requires input from the download link and if it does not change with each query, I cannot download in scale.
I tried to do it this way
download.file("https://cadprev.previdencia.gov.br/Cadprev/faces/pages/modulos/dair/consultarDemonstrativos.xhtml", destfile = "C:/Users/holiveira/Desktop")
but I couldn’t download, and I can’t create a mechanism to scale.
I would like to have a vector with several names of municipalities and to make the automated download the pdf files of all
The link does not change but the parameter viewstate changes, just pass it in the post request.

Update your question with how you are doing that I show you how you need to do, your question has little information.
