Dear Matt,
I've solved the problem with the help of a colleague. The correct proxy settings where missing.
Set http = CreateObject("WinHttp.WinHttpRequest.5.1") http.setProxy 2, strProxy
where strProxy contains the proxy string.
Best regards Michael

Hi Michael,
It's been a long time since I used VBA, but this routine works when I run it in Excel - the zip file is downloaded to the local disc:
strDownload = "0211656-200613084148143" Set http = CreateObject("WinHttp.WinHttpRequest.5.1") strURL_Request = "https://api.gbif.org/v1/occurrence/download/"https://api.gbif.org/v1/occurrence/download/ & strDownload http.Open "GET", strURL_Request, False http.Send Debug.Print (http.Status)
' (I have not bothered to parse the JSON output.) strURL_ZIP = "https://api.gbif.org/v1/occurrence/download/request/0211656-200613084148143...."https://smex-ctp.trendmicro.com:443/wis/clicktime/v1/query?url=https%3a%2f%2fapi.gbif.org%2fv1%2foccurrence%2fdownload%2frequest%2f0211656%2d200613084148143.zip&umid=80cb9736-359f-40eb-816d-a014d8f099b4&auth=4456e5223a495a0240a5eada979a61a7fdbe9da6-b4c1e3909bf198573829b11759f8dd7372547122 http.Open "GET", strURL_ZIP, False http.Send Debug.Print (http.Status)
' From https://stackoverflow.com/questions/59598416/vba-download-form-url-with-logi... Set oStream = CreateObject("ADODB.Stream") oStream.Open oStream.Type = 1 oStream.write http.ResponseBody oStream.SaveToFile "C:\Users...\Documents\download.zip", 2 oStream.Close Debug.Print ("Completed")
Our servers don't block this query, so I think it's most likely to be a restriction on your own network / computer. Note there is an HTTP redirect from the API server to the download server, but WinHttpRequest follows this automatically.
Kind regards,
Matt

I'm trying to query and download occurences with some subs written in VBA. While querying works fine, download leads to errors.
At the end oft he query, I have a download link for a ZIP-archive. Putting this into a browser address field lets me download the archive. Giving it to a VBA-Object returns errors.
E.g.,
Set http = CreateObject("WinHttp.WinHttpRequest.5.1") strURL_Request = "https://api.gbif.org/v1/occurrence/download/"https://api.gbif.org/v1/occurrence/download/ & strDownload http.setTimeouts 30000, 30000, 30000, 30000 http.Open "GET", strURL_Request, False http.send
returns a jason file that contains the download link. I extract this link and use it as parameter in the next step:
http.Open "GET", strURL_ZIP, False http.send
This results in a timeout. Using "Microsoft.XMLHTTP" alternativly returns "Access denied"
Is this a problem with our network restrictions or does the GBIF server block the query?
Kind regards Michael
