PowerShell Scripting to Replicate Todoist Data to MySQL

The CData Cmdlets for Todoist offer live access to Todoist data from within PowerShell. Using PowerShell scripts, you can easily automate regular tasks like data replication. This article will walk through using the CData Cmdlets for Todoist and the CData Cmdlets for MySQL in PowerShell to replicate Todoist data to a MySQL database.

After obtaining the needed connection properties, accessing Todoist data in PowerShell and preparing for replication consists of four basic steps.

Start by setting the Profile connection property to the location of the Todoist Profile on disk (e.g. C:\profiles\Todoist.apip). Next, set the ProfileSettings connection property to the connection string for Todoist (see below).

Todoist API Profile Settings

To authenticate to Todoist, and connect to your own data or to allow other users to connect to their data, you can use the OAuth standard.

First, register an OAuth application with Todoist. To do so, go to App Management Console, create a new application and configure a valid OAuth redirect URL. Your Oauth application will be assigned a client id and a client secret.

After setting the following connection properties, you are ready to connect:

• AuthScheme: Set this to OAuth.
• InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
• OAuthClientId: Set this to the client_id that is specified in you app settings.
• OAuthClientSecret: Set this to the client_secret that is specified in you app settings.
• CallbackURL: Set this to the Redirect URI that is specified in your app settings

Collecting Todoist Data

1. Install the module:

   Install-Module APICmdlets

2. Connect to Todoist:

    $api = Connect-API -Profile $Profile -Authscheme $Authscheme -OAuthClientId $OAuthClientId -OAuthClientSecret $OAuthClientSecret -CallbackUrl $CallbackUrl
    

3. Retrieve the data from a specific resource:

    $data = Select-API -Connection $api -Table "Tasks"
    

   You can also use the Invoke-API cmdlet to execute pure SQL-92 statements:

    $data = Invoke-API -Connection $api -Query 'SELECT * FROM Tasks WHERE Completed = @Completed' -Params @{'@Completed'='false'}
    

4. Save a list of the column names from the returned data.

    $columns = ($data | Get-Member -MemberType NoteProperty | Select-Object -Property Name).Name
    

Inserting Todoist Data into the MySQL Database

With the data and column names collected, you are ready to replicate the data into a MySQL database.

1. Install the module:

   Install-Module MySQLCmdlets

2. Connect to MySQL, using the server address and port of the MySQL server, valid user credentials, and a specific database with the table in which the data will be replicated:

    $mysql = Connect-MySQL -User $User -Password $Password -Database $Database -Server $Server -Port $Port
    

3. Loop through the Todoist data, store the values, and use the Add-MySQL cmdlet to insert the data into the MySQL database, one row at a time. In this example, the table will need to have the same name as the Todoist resource (Tasks) and to exist in the database.

    $data | % {
    $row = $_
    $values = @()
    $columns | % {
    $col = $_
    $values += $row.$($col)
    }
    Add-MySQL -Connection $mysql -Table "Tasks" -Columns $columns -Values $values
    }
    

You have now replicated your Todoist data to a MySQL database. This gives you freedom to work with Todoist data in the same way that you work with other MySQL tables, whether that is performing analytics, building reports, or other business functions.

Notes

• Once you have connected to Todoist and MySQL in PowerShell, you can pipe command results to perform the replication in a single line:

   Select-API -Connection $api -Table "Tasks" | % {
   $row = $_
   $values = @()
   $columns | % {
   $col = $_
   $values += $row.$($col)
   }
   Add-MySQL -Connection $mysql -Table "Tasks" -Columns $columns -Values $values
   }
   

• If you wish to replicate the Todoist data to another database using another PowerShell module, you will want to exclude the Columns, Connection, and Table columns from the data returned by the Select-API cmdlet since those columns are used to help pipe data from one CData cmdlet to another:

   $columns = ($data | Get-Member -MemberType NoteProperty | Select-Object -Property Name).Name | ? {$_ -NotIn @('Columns','Connection','Table')}
