converting cURL request to asp.net c#

Question

i try to work around converting this to c# but i cant understand the tags like -H others am familiar with like the BVN and secret key are clear to me, but i'm literally at cross road.

curl https://api.paystack.co/bank/resolve_bvn/:BVN

-H "Authorization: Bearer YOUR_SECRET_KEY"

-X GET

this enlightened me but i'm new to using curl

Answer 1

I only want to explain command flags.

-H means request header. In your case, you need to set header with name Authorization to the secret key Bearer YOUR_SECRET_KEY eg Bearer abcd123566 where abcd123566 is your secret key.

-X GET means your request method (HTTP verb) should be GET

Answer 2

-H means the headers of the request. In C# the code would look something like this:

private static HttpClient httpClient = new HttpClient();

var uri = new Uri("https://api.paystack.co/bank/resolve_bvn/:BVN");
var reqMessage = new HttpRequestMessage(HttpMethod.Get, uri);
reqMessage.Headers.Authorization = new AuthenticationHeaderValue("Bearer", "YOUR_SECRET_KEY")

// Setting the request content (including content-type)
reqMessage.Content = new StringContent("Content of request", Encoding.UTF8, "application/json");

var resp = await httpClient.SendAsync(reqMessage);
