Cmdlets for HubDB

Build 24.0.8963

Establishing a Connection

With the CData Cmdlets users can install a data module, set the connection properties, and start scripting. This section provides examples of using our HubDB Cmdlets with native PowerShell cmdlets, like the CSV import and export cmdlets.

Installing and Connecting

If you have PSGet, installing the cmdlets can be accomplished from the PowerShell Gallery with the following command. You can also obtain a setup from the CData site. 

Install-Module HubDBCmdlets

The following line is then added to your profile, loading the cmdlets on the next session: 

Import-Module HubDBCmdlets;

You can then use the Connect-HubDB cmdlet to create a connection object that can be passed to other cmdlets: 

$conn = Connect-HubDB -AuthScheme "OAuth" -OAuthClientID "MyOAuthClientID" -OAuthClientSecret "MyOAuthClientSecret" -CallbackURL "http://localhost:33333"

Connecting to HubDB

There are two authentication methods available for connecting to HubDB data source: OAuth Authentication with a public HubSpot application and authentication with a Private application token.

OAuth

AuthScheme must be set to OAuth in all OAuth flows. The following OAuth flows assume you have done so.

Desktop Applications

You must create a custom OAuth application to connect. See Creating a Custom OAuth App a procedure.

Get and Refresh the OAuth Access Token

After setting the following, you are ready to connect:

  • OAuthClientId: Set this to the client Id assigned when you registered your application.
  • OAuthClientSecret: Set this to the client secret assigned when you registered your application.
  • CallbackURL: Set this to the redirect URI defined when you registered your application.
When you connect, the cmdlet opens HubDB's OAuth endpoint in your default browser. Log in and grant permissions to the application. The cmdlet refreshes the access token automatically when it expires.

Headless Machines

To configure the driver to use OAuth with a user account on a headless machine, you need to authenticate on another device that has an internet browser.

  1. Choose one of two options:
    • Option 1: Obtain the OAuthVerifier value as described in "Obtain and Exchange a Verifier Code" below.
    • Option 2: Install the cmdlet on a machine with an internet browser and transfer the OAuth authentication values after you authenticate through the usual browser-based flow, as described in "Transfer OAuth Settings" below.
  2. Then configure the cmdlet to automatically refresh the access token on the headless machine.

Option 1: Obtain and Exchange a Verifier Code

To obtain a verifier code, you must authenticate at the OAuth authorization URL.

Follow the steps below to authenticate from the machine with an internet browser and obtain the OAuthVerifier connection property.

  1. Set the following properties:
    • InitiateOAuth: Set to OFF.
    • OAuthClientId: Set to the client Id assigned when you registered your application.
    • OAuthClientSecret: Set to the client secret assigned when you registered your application.
  2. Call the GetOAuthAuthorizationURL stored procedure with the appropriate CallbackURL. Open the URL returned by the stored procedure in a browser.
  3. Log in and grant permissions to the cmdlet. You are then redirected to the redirect URI. There will be a parameter called code appended to the redirect URI. Note the value of this parameter. Later you will set this in the OAuthVerifier connection property.
Next, you need to exchange the OAuth verifier code for OAuth refresh and access tokens.

On the headless machine, set the following connection properties to obtain the OAuth authentication values:

  • InitiateOAuth: Set this to REFRESH.
  • OAuthVerifier: Set this to the noted verifier code (the value of the code parameter in the redirect URI).
  • OAuthClientId: Set this to the client Id in your OAuth application settings.
  • OAuthClientSecret: Set this to the client secret in the OAuth application settings.
  • OAuthSettingsLocation: Set this to persist the encrypted OAuth authentication values to the specified location.

Test the connection to generate the OAuth settings file, then re-set the following properties to connect:

  • InitiateOAuth: Set this to REFRESH.
  • OAuthClientId: Set this to the client Id assigned when you registered your application.
  • OAuthClientSecret: Set this to the client secret assigned when you registered your application.
  • OAuthSettingsLocation: Set this to the location containing the encrypted OAuth authentication values. Make sure this location gives read and write permissions to the cmdlet to enable the automatic refreshing of the access token.

Option 2: Transfer OAuth Settings

Prior to connecting on a headless machine, you need to install and create a connection with the driver on a device that supports an internet browser. Set the connection properties as described in "Desktop Applications" above.

After completing the instructions in "Desktop Applications", the resulting authentication values are encrypted and written to the location specified by OAuthSettingsLocation. The default filename is OAuthSettings.txt.

Test the connection to generate the OAuth settings file, then copy the OAuth settings file to your headless machine.

On the headless machine, set the following connection properties to connect to data:

  • InitiateOAuth: Set this to REFRESH.
  • OAuthClientId: Set this to the client Id assigned when you registered your application.
  • OAuthClientSecret: Set this to the client secret assigned when you registered your application.
  • OAuthSettingsLocation: Set this to the location of the OAuth settings file you copied from the machine with the browser. Make sure this location gives read and write permissions to the cmdlet to enable the automatic refreshing of the access token.

Private App

To connect using a Hubspot private application token, set the AuthScheme property to PrivateApp.

You can generate a private application token by following the steps below:

  1. In your HubDB account, click the settings icon (the gear) in the main navigation bar.
  2. In the left sidebar menu, navigate to Integrations > Private Apps.
  3. Click Create private app.
  4. On the Basic Info tab, configure the details of your application (name, logo, and description).
  5. On the Scopes tab, select Read or Write for each scope you want your private application to be able to access.
    • A minimum of hubdb and crm.objects.owners.read is required to access tables.
  6. After you are done configuring your application, click Create app in the top right.
  7. Review the info about your application's access token, click Continue creating, and then Show token.
  8. Click Copy to copy the private application token.

To connect, set PrivateAppToken to the private application token you retrieved.

Retrieving Data

The Select-HubDB cmdlet provides a native PowerShell interface for retrieving data: 

$results = Select-HubDB -Connection $conn -Table "NorthwindProducts" -Columns @("PartitionKey, Name") -Where "Industry='Floppy Disks'"
The Invoke-HubDB cmdlet provides an SQL interface. This cmdlet can be used to execute an SQL query via the Query parameter.

Piping Cmdlet Output

The cmdlets return row objects to the pipeline one row at a time. The following line exports results to a CSV file: 

Select-HubDB -Connection $conn -Table NorthwindProducts -Where "Industry = 'Floppy Disks'" | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\myNorthwindProductsData.csv -NoTypeInformation

You will notice that we piped the results from Select-HubDB into a Select-Object cmdlet and excluded some properties before piping them into an Export-CSV cmdlet. We do this because the CData Cmdlets append Connection, Table, and Columns information onto each row object in the result set, and we do not necessarily want that information in our CSV file.

However, this makes it easy to pipe the output of one cmdlet to another. The following is an example of converting a result set to JSON: 

 
PS C:\> $conn  = Connect-HubDB -AuthScheme "OAuth" -OAuthClientID "MyOAuthClientID" -OAuthClientSecret "MyOAuthClientSecret" -CallbackURL "http://localhost:33333"
PS C:\> $row = Select-HubDB -Connection $conn -Table "NorthwindProducts" -Columns (PartitionKey, Name) -Where "Industry = 'Floppy Disks'" | select -first 1
PS C:\> $row | ConvertTo-Json
{
  "Connection":  {

  },
  "Table":  "NorthwindProducts",
  "Columns":  [

  ],
  "PartitionKey":  "MyPartitionKey",
  "Name":  "MyName"
}

Deleting Data

The following line deletes any records that match the criteria: 

Select-HubDB -Connection $conn -Table NorthwindProducts -Where "Industry = 'Floppy Disks'" | Remove-HubDB

Modifying Data

The cmdlets make data transformation easy as well as data cleansing. The following example loads data from a CSV file into HubDB, checking first whether a record already exists and needs to be updated instead of inserted. 

Import-Csv -Path C:\MyNorthwindProductsUpdates.csv | %{
  $record = Select-HubDB -Connection $conn -Table NorthwindProducts -Where ("Id = `'"+$_.Id+"`'")
  if($record){
    Update-HubDB -Connection $conn -Table NorthwindProducts -Columns @("PartitionKey","Name") -Values @($_.PartitionKey, $_.Name) -Where "Id  = `'$_.Id`'"
  }else{
    Add-HubDB -Connection $conn -Table NorthwindProducts -Columns @("PartitionKey","Name") -Values @($_.PartitionKey, $_.Name)
  }
}
