Add x-api-key to request HTTP header using web.config

Question

A web service that I'm trying to consume requires that I add x-api-key to the HTTP header of the request. Is it possible to add this new header to the request using the web.config? I've tried to add the header element to the endpoint like the example below, but keep getting 403-Forbidden:

<endpoint address="webserviceurl"
    behaviorConfiguration="myBehavior" binding="customBinding"
    bindingConfiguration="myBinding" contract="myContract"
    name="serviceName">
    <headers>
      <x-api-key xmlns="webserviceurl">"key"</x-api-key>
    </headers>
</endpoint>

@DanielA.White both answers regarding web.config is exactly what I'm doing. — jcs, Mar 03 '20 at 15:36
same thing. I think the problem is that it adds to the SOAP headers, not the HTTP headers. — jcs, Mar 03 '20 at 15:46

Couldn't find a way to do it through web.config, so I developed a solution based on this answer:

WSClient client = new WSClient("endpointName");

using (OperationContextScope scope = new OperationContextScope(client.InnerChannel))
{
    WebOperationContext.Current.OutgoingRequest.Headers.Add("X-API-KEY", "key");
    WSRequest req = new WSRequest();
    WSResponse resp = client.WSMethod(req);
}
