Integrating RapidAPI with VBA Excel for Domain WhoIs Lookups

I’m facing issues configuring RapidAPI in VBA to fetch domain WhoIs data in Excel. Any advice?

Function FetchWhoisData(domainInput As String) As String
    Dim endpoint As String, httpReq As Object
    Set httpReq = CreateObject("MSXML2.XMLHTTP")
    endpoint = "https://sampleapi.example.com/whois?domain=" & domainInput
    httpReq.Open "GET", endpoint, False
    httpReq.setRequestHeader "API-Key", "your_api_key_here"
    httpReq.send
    FetchWhoisData = httpReq.responseText
End Function

Sub ProcessDomains()
    Dim cellItem As Range
    For Each cellItem In Range("A2:A20")
        If cellItem.Value <> "" Then cellItem.Offset(0, 1).Value = FetchWhoisData(cellItem.Value)
    Next cellItem
End Sub

I encountered similar challenges when integrating RapidAPI with VBA for domain lookups. In my case, ensuring that the exact formatting of the HTTP request headers matched the API documentation was key. I also incorporated a retry mechanism which allowed my script to gracefully handle intermittent network delays. It turned out that using a small sleep between successive requests helped mitigate rate limit issues even though they weren’t documented explicitly. Overcoming these obstacles required some patience and trial, but the final solution proved to be robust in production.

hey hermione, try checking ur api key and endpoint; sometimes msxml2 fails silently. also, adding some errror handling for network issues might help. hopefully that sorts it out!

Integrating RapidAPI with VBA can be quite delicate. In my experience, one important factor is ensuring that the service’s expected response format is consistently met. I discovered that inserting an explicit timeout and checking for error codes after the request can prevent the function from returning incomplete data. Revisiting the API documentation for header specifications and the exact structure for parameter encoding also helped streamline the process. Logging the actual responses during troubleshooting was essential for pinpointing what was causing the mismatch, thus enabling a precise fix for the issue.

hey, i solved a similar glitch by swapping msxml2.xmlhttp for winhttp.winhttprequest.5.1 and adding a slight delay after sending. check that your endpoint encodes correctly too. it might just help with the timeouts you were seeing.
