Automating Power BI Gateway administration by using Powershell

Folks,

I have been looking the way of automate gateway data source administration by using Powershell or whatever programming language that allows me to perform the following:

Get Gateways
Create Data Source (gateways)
Get data sources (gateways)
Get data source users (gateways)
Add data source user (gateways)
Delete data source user (gateways)
Delete data source (gateways)
Set Credentials

So far, I know that there is an Power BI REST API available, but the information provided isn´t much. Does anyone have been dealing with this same stuff? The reason why I am asking this is because I am hoping to develop a small application that handle all gateway data source administration.

 

I look forward for your comments.

 

Thanks in advance,

Regards.

One thing unclear is about the "credentials" field when creating a datasource. I capture the network from Power BI Service and it shows some parsed/encrypted string. It seems the credentials(username and password) are encrpted in javascript and the documentation doesn't mention about it. I'm consulting this internally.

Hi all. Here's how to update on-prem datasource credentials using PowerShell:

How to update credentials for an on-prem Power BI data source using PowerShell 

Hope this helps,

This has been asked by previous people, but still no answer that I can see. How can I get the 

gateway.PublicKey.Exponent, gateway.PublicKey.Modulus

values for the above which are needed when calling UpdateDatasourceWithHttpMessagesAsync ? When I call the GetGatewaysWithHttpMessagesAsync  to get a gateway this always returns nothing. 

 

I used to use the PatchDatasource but this is not available in V2 api.

I used the Get Gateways REST Api method to get the gateways. The returned array contains Gateway Entity objects. The Gateway Entity object has public key information.

Hi 

 

I am trying to create a datasource from gateway, below is the request:

 

POST https://api.powerbi.com/v1.0/myorg/gateways/{gateway-id/datasources


{
"dataSourceType": "Oracle",
"connectionDetails": "{\"server\":\"myserver\"}",
"datasourceName": "PostAPI Datasource",
"credentialDetails": {
"credentialType": "Basic",
"credentials": "encryptedvalue",
"encryptedConnection": "Encrypted",
"encryptionAlgorithm": "RSA-OAEP",
"privacyLevel": "None"
}
}

 

I am receiving the following error: 400 bad request 

{
    "error": {
        "code": "DM_GWPipeline_Gateway_DataSourceAccessError",
        "pbi.error": {
            "code": "DM_GWPipeline_Gateway_DataSourceAccessError",
            "parameters": {},
            "details": [],
            "exceptionCulprit": 1
        }
    }
}

Could anyone please help!

One thing unclear is about the "credentials" field when creating a datasource. I capture the network from Power BI Service and it shows some parsed/encrypted string. It seems the credentials(username and password) are encrpted in javascript and the documentation doesn't mention about it. I'm consulting this internally.

@Eric_Zhang Thanks for the C# code. As I understand, this is from Power BI .net SDK from here.

What is the PowerShell equivalent? How can we create a data source in Power BI gateway(s) through PowerShell? 

Thanks
Kaz 

Any solutions here for creating a datasource with Power Shell?

 

I also suggested / asked how to skip the credentials when creating a datasource see here:

https://community.powerbi.com/t5/Developer/Power-BI-REST-API-via-Powershell-Create-Datasource/m-p/13...

@Eric_Zhang

In addition, about the encrypted credentials, if you find an answer please let me know! I will do the same.

I´m gonna start to digging on this.

Thanks!

@Eric_Zhang Thanks so much! This is useful.

Can I ask what is the documentation that you are following? As far as I know, we got this:

Power BI REST API reference

Power BI Documentation - Power BI REST API Reference

But I think that there is not much detail there. Do you have something more?

 

Thanks again, I appreciate your time.

Regards.

I use both above links and actually have no more resource. I'm also new to those APIs and I just test them by myself. Fortunately we could consult internally to the product team, so if we have confusion, we can get confirmation from them.

 

As to the encrypted credential, I've got some clue. I'll share it public once I got more comfirmation.

 

By the way, currently I‘m composing an article on Power BI REST APIs demos. You could see any update here.

Thank you so much! @Eric_Zhang

@jboronat

Got the confirmation. See below class to encrypt a credential

 

public static class AsymmetricKeyEncryptionHelper
    {

        private const int SegmentLength = 85;
        private const int EncryptedLength = 128;


        /// <summary>
        /// 
        /// </summary>

        /// <param name="gatewaypublicKeyModulus"></param> gateway publicKey Modulus field, you can get it from the get gateways api response json
        /// <returns></returns>
        public static string EncodeCredentials(string userName, string password, string gatewaypublicKeyExponent, string gatewaypublicKeyModulus)
        {
            // using json serializer to handle escape characters in username and password
            var plainText = string.Format("{{\"credentialData\":[{{\"value\":{0},\"name\":\"username\"}},{{\"value\":{1},\"name\":\"password\"}}]}}", JsonConvert.SerializeObject(userName), JsonConvert.SerializeObject(password));
            using (RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(EncryptedLength * 8))
            {
                var parameters = rsa.ExportParameters(false);
                parameters.Exponent = Convert.FromBase64String(gatewaypublicKeyExponent);
                parameters.Modulus = Convert.FromBase64String(gatewaypublicKeyModulus);
                rsa.ImportParameters(parameters);
                return Encrypt(plainText, rsa);
            }
        }

        private static string Encrypt(string plainText, RSACryptoServiceProvider rsa)
        {
            byte[] plainTextArray = Encoding.UTF8.GetBytes(plainText);

            // Split the message into different segments, each segment's length is 85. So the result may be 85,85,85,20.
            bool hasIncompleteSegment = plainTextArray.Length % SegmentLength != 0;

            int segmentNumber = (!hasIncompleteSegment) ? (plainTextArray.Length / SegmentLength) : ((plainTextArray.Length / SegmentLength) + 1);

            byte[] encryptedData = new byte[segmentNumber * EncryptedLength];
            int encryptedDataPosition = 0;

            for (var i = 0; i < segmentNumber; i++)
            {
                int lengthToCopy;

                if (i == segmentNumber - 1 && hasIncompleteSegment)
                    lengthToCopy = plainTextArray.Length % SegmentLength;
                else
                    lengthToCopy = SegmentLength;

                var segment = new byte[lengthToCopy];

                Array.Copy(plainTextArray, i * SegmentLength, segment, 0, lengthToCopy);

                var segmentEncryptedResult = rsa.Encrypt(segment, true);

                Array.Copy(segmentEncryptedResult, 0, encryptedData, encryptedDataPosition, segmentEncryptedResult.Length);

                encryptedDataPosition += segmentEncryptedResult.Length;
            }

            return Convert.ToBase64String(encryptedData);
        }
    }

You can use it as

 

var credentials = AsymmetricKeyEncryptionHelper.EncodeCredentials(username, password, gateway.PublicKey.Exponent, gateway.PublicKey.Modulus);

You said in your code snippet that we get the gateway from the 'Get Gateways Api'.  But when I call Gateways.GetGatewaysAsync, it returns an empty set.  I can call GetGatewayDatasourcesInGroupAsync for my dataset and get a gatewayId from that.  However, if I call Gateways.GetGatewayByIdAsync with that gatewayId, it throws an error.

 

Basically, I need help getting the PublicKey.Exponent and PublicKey.Modulus.

 

me too I get the same error, it seems that a getGatewayInGroup is not available. I would really appreciate some docs on the topic, thanks!

Can we get some attention on this please, and a working sample that supports the Power BI Embedded scenario?

 

I think I am confused about the term 'gateway' in Power BI. Generally it seems to mean a gateway to on-prem data sources (via the gateway executable) but it also seems to be thrown about in the context of setting credentials to access cloud data sources... is that correct?

 

E.g. what is the replacement for PowerBIClient.Gateways.PatchDatasource (in its various guises) in the V2 API?

 

A sample that shows setting the credentials for a PBIX that contains multiple data sources; e.g. Azure SQL, Azure Table Storage, would be great! I want to migrate away from Azure Power BI workspaces to Power BI Embedded but until I can get this piece to work... no dice!

 

Various people across this forum have stated they are attempting to update the code in the 'Provisioning' sample to the V2 API, but frankly... we shouldn't have to do this ourselves Microsoft!

me too, in general I would appreciate some docs on how to do that
