Dear colleagues,
We are using XQuery with BaseX for the development of hundreds of validation rules for CDISC Standards ("Open Rules for CDISC Standards").
For some of these rules we need a lookup using a RESTful web server located at CDISC. Until now, that server used basic authentication until now, but they are moving to using an Azure API key.

For the new mechanism, the curl request is:

     curl -X GET https://ngp-apim-dev.azure-api.net/api/mdr/products \
    
     -H "Accept: application/json" \
    
     -H "Ocp-Apim-Subscription-Key: abcdef0123456789abcdef0123456789"
    
     So, based on the documentation at https://docs.basex.org/wiki/HTTP_Client_Module, for XQuery I used:
     
let $response := http:send-request(
     
<http:request method='get' href='https://ngp-apim-dev.azure-api.net/api/mdr/products'>
     
<http:header name="Ocp-Apim-Subscription-Key" value="{$apikey}"/> 
     
</http:request>)
    
     and:
    
     let $response := http:send-request(
     
<http:request method='get'>
     
<http:header name="Ocp-Apim-Subscription-Key" value="{$apikey}"/> 
     
</http:request>,'https://ngp-apim-dev.azure-api.net/api/mdr/products')
    
     where $apikey is my personal key, which works when working with curl or in a Java program.
    
     but I get a "Connection failed".

From a few experiments, it looks as the server is reached, but then refuses to do something with the request. I cannot see however what the details of the failure is.

Any idea what I am doing wrong?

Many thanks in advance,
