Sending a POST Request in AL code for Stripe Checkout API

I'm trying to create a Stripe checkout session in Business Central. but I'm facing an issue with passing the content type as "application/x-www-form-urlencoded". I've tried setting the header header.Add('Content-Type', 'application/x-www-form-urlencoded') but I'm facing this error.

This is my Code..

procedure StripeAPI()
    Var
        client: HttpClient;
        cont: HttpContent;
        header: HttpHeaders;
        response: HttpResponseMessage;
        Jobject: JsonObject;
        tmpString: Text;
        TypeHelper: Codeunit "Type Helper";
        granttype: text;
        clienid: text;
        username: text;
        password: text;
    Begin
        CancelURL1 := 'https://example.com';
        success_url1 := 'https://example.com';
        line_items_currency1 := 'usd';
        line_items_Nam := 'Shirt';
        line_items_unitAmoun := '2000';
        LineAmountQuantit := '1';
        Mode1 := 'payment';
        PaymentMethodType1 := 'card';

        tmpString := 'mode='   TypeHelper.UrlEncode(Mode1)   '&line_items[0][price_data][unit_amount]='   TypeHelper.UrlEncode(line_items_unitAmoun)   '&cancel_url='   TypeHelper.UrlEncode(CancelURL1)   '&success_url='   TypeHelper.UrlEncode(success_url1)   '&line_items[0][price_data][currency]='   TypeHelper.UrlEncode(line_items_currency1)   '&line_items[0][price_data][product_data][name]='   TypeHelper.UrlEncode(line_items_Nam)   '&line_items[0][quantity]='   TypeHelper.UrlEncode(LineAmountQuantit)   '&payment_method_types[0]='   TypeHelper.UrlEncode(PaymentMethodType1);

        Message(tmpString);
        cont.WriteFrom(tmpString);
        cont.ReadAs(tmpString);

        cont.GetHeaders(header);
        header := client.DefaultRequestHeaders;
        header.Add('charset', 'UTF-8');
        header.Remove('Content-Type');
        header.Add('Content-Type', 'application/x-www-form-urlencoded');
        header.Add('Authorization', 'Bearer *********************************************');

        client.Post('**********************', cont, response);
        response.Content.ReadAs(responseText);
    end;

I have also checked that the tmpString a variable that contains the data in the text format url embedded and it is working fine in Postman when selecting "application/x-www-form-urlencoded".
