Create Todoist-Connected Business Apps in AppSheet

AppSheet provides a no-code development platform for application software, which allows users to create mobile, tablet, and web applications. When paired with CData Connect Server, you get instant access to Todoist data for business applications. This article shows how to create a virtual database for Todoist in Connect Server and build a simple app from Todoist data in AppSheet.

CData Connect Server provides a pure SQL Server interface for Todoist, allowing you to easily build reports from live Todoist data in AppSheet — without replicating the data to a natively supported database. As you build visualizations, AppSheet generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect Server pushes all supported SQL operations (filters, JOINs, etc) directly to Todoist, leveraging server-side processing to quickly return the requested Todoist data.

Create a Virtual SQL Server Database for Todoist Data

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

1. Login to Connect Server and click Connections.
2. Select "Todoist" from Available Data Sources.
3. Enter the necessary authentication properties to connect to Todoist.

   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, you will need to 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
4. Click Save Changes
5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to Todoist data from AppSheet.

Connect to Todoist in AppSheet

The steps below outline connecting to CData Connect Server from AppSheet to create a new Todoist data source.

1. Log into AppSheet.
2. Click the letter icon in the top-right corner, then select Account Settings.
3. Click the Sources tab and click + New Data Source. Then, select Cloud Database.
4. Set the connection information to the following:
   • Type: SQLServer
   • Server: the endpoint for your instance, including port, for example, CONNECT_SERVER_URL,3306
   • Database: the virtual database, for example, API1
   • Username: a Connect Server user with permissions for the database
   • Password: the password for the above Connect Server user
   • SSL: Require SSL
5. Click Test. Then, click Authorize Access.

Create an App

Once you create the data source for Todoist, you can start building apps on Todoist data.

1. Start by clicking + Create -> App -> Start with existing data.
2. Name the app and select an appropriate category, based on your data. Then, click Choose your data.
3. Select the newly created data source (e.g., API1).
4. Select the table or view with the data you want.

At this point, you can configure the design of your app, selecting which columns from the selected table to display, use as labels, and more. Preview the app in the preview panel and then publish or share it when ready.
