How to use curl within business central (c/AL)

Question

How to post and get data from external url into business central AL codeunit using curl. Any other alternative method/approach is welcomed.

Answer 1

In AL the HttpClient Data Type is what you are looking for when communicating between external systems, see: Call external services with the HttpClient data type

    local procedure GetRequest() ResponseText: Text
    var
        Client: HttpClient;
        IsSuccessful: Boolean;
    begin
        IsSuccessful := Client.Get('https://httpcats.com/418.json', HttpResponseMessage);

        // error handling

        HttpResponseMessage.Content().ReadAs(ResponseText);
    end;

Modify the above example to your own needs. It's also a good practice to save URLs into their own variable with Locked = true and maybe even a placeholder:

var
    httpCatsUrl: Label 'https://httpcats.com/%1.json', Locked = true, Comment = '%1=http status code';
