Question: How to use the custom API Request to generate an AnonymousLinkWithExpirationDate

[Ironbell]

Hey there!

I'm enjoying the PNP Core SDK very much, it's clean and well documented, so thank you a lot for that.
I understand it is still work in progress, so not all API calls that you can do on sharepoint are already wrapped - but I found that there is a solution for that with the custom API calls.

https://pnp.github.io/pnpcore/using-the-sdk/basics-customapirequests.html

I also found the definition for the API call I want to use:

<FunctionImport Name="SP_Web_CreateAnonymousLinkWithExpiration" ReturnType="Edm.String">
					<Parameter Name="url" Type="Edm.String" />
					<Parameter Name="isEditLink" Type="Edm.Boolean" Nullable="false" />
					<Parameter Name="expirationString" Type="Edm.String" />
</FunctionImport>

Sadly I don't find a lot of information online on how to use this in a call. What I have is now something like

var context = (context factory creates the PnPContext)
var apiRequest = new ApiRequest(ApiRequestType.SPORest, "_api/SP.Web.CreateAnonymousLinkWithExpiration");
var response = context.Web.ExecuteRequest(apiRequest);

How am I supposed to put the parameters url, isEditLink and expiration string in this request? It would be part of the Url I guess? I just can't find any examples of how to use the syntax.

Also I'd love to have this feature wrapped in PnP Core, but I understand that it's going to take a while.

Thank you for your help and work

Found my own answer after trying for quite a bit, just in case anyone needs it :)

private static string GetFileAccessUrl(PnPContext context, string serverRelativeUrl)
{
    var host = context.Uri.Host;
    var scheme = context.Uri.Scheme;
    
    var url = $"{scheme}://{host}{serverRelativeUrl}";
    var expirationString = DateTime.Now.AddDays(1).ToString("s", System.Globalization.CultureInfo.InvariantCulture);
    var isEditLink = false;
    
    var request = new
    {
        url,
        isEditLink,
        expirationString,
    };

    var body = JsonConvert.SerializeObject(request, new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore });

    var apiRequest = new ApiRequest(HttpMethod.Post, ApiRequestType.SPORest, "_api/SP.Web.CreateAnonymousLinkWithExpiration", body);
    var response = context.Web.ExecuteRequest(apiRequest);

    if (response.StatusCode == HttpStatusCode.OK)
    {
        return response.Response;
    }

    return null;
 }
