Hello,

I am trying to automatically import a PBIX file into my workspace with Power BI Embedded, currently using the code below, but I get the error: 

HTTP Error 400. The request is badly formed.

I really couldn't find the correct syntax to send it via PHP cURL, currently using this:

 

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "https://api.powerbi.com/v1.0/collections/$workspace_collection_name/workspaces/$workspace_id/imports?datasetDisplayName=$display_name&nameConflict=$nameConflict");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);

curl_setopt($ch, CURLOPT_POST, TRUE);
$boundary = "BOUNDARY";

$postdata = "--". $boundary . "\r\n";
$postdata .= "Content-Disposition: form-data;\r\n";
$postdata .= "\r\n";
$postdata .= "{".file_get_contents($file_path)."}";
$postdata .= "--".$boundary . "--\r\n";

curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);

curl_setopt($ch, CURLOPT_HTTPHEADER, array(
  "Authorization: AppKey  $access_key",
  "Content-Type: multipart/form-data; boundary=$boundary"  
)); 

$response = curl_exec($ch);
curl_close($ch);
var_dump($response);

Anyone would spot what I am doing wrong?

Thanks

The error shows nothing on PHP specific I think, it tells that there's something wrong in the request. I don't know PHP, however below C# demo can compose a good request and import a pbix to my workspace. You can reference the demo and tweak the request in PHP accordingly.

using System;
using System.Net;
using System.IO;
namespace PBIGettingStarted
{
    class Program
    {
        //Access key for app token
        private static string accessKey = "yourAccesskey";
        //Power BI app token values
        private static string workspaceCollectionName = "yourworkspacecollectioname";
        private static string workspaceId = "yourworkspaceid";
        private static string pbixFileName = "pbixname.pbix";
        static void Main(string[] args)
        {
            //Imports uri
            var uri = String.Format
("https://api.powerbi.com/v1.0/collections/{0}/workspaces/{1}/imports?datasetDisplayName=SampleImport",
workspaceCollectionName, workspaceId);
            //PBIX file to import
  
            string fileName = @"C:\test\kpi.pbix";

            //Create web request
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
            //Import Request format:

            }
            //Get response
            using (HttpWebResponse response = request.GetResponse() as System.Net.HttpWebResponse)
            {
                //If Import succeeds, StatusCode = Accepted 
                var responseStatusCode = response.StatusCode.ToString();
            }
        }
    }
