I'm trying to extract data from the website https://www.tax.service.gov.uk/check-council-tax-band/search. After submitting a postcode (e.g. LS26 0AG) it returns a coded URL with results, which I want to extract.
I've got the last part (extracting the results) working well but I can't figure out how to use HTTPCaller to submit a postcode and get the URL that is returned.
The form name is "postcode" but when I set it up and run I get a "HTTP/1.1 400 Bad Request" error.
Can anyone help please?
